UK Casino Bonuses and Free Spins

For UK players looking to maximise value, starting with a 1 pound deposit casino is a smart way to test a site without risking much. Many platforms also reward new sign-ups with a small batch of 10 free spins on selected slots, giving you a taste of the action. If you prefer a larger commitment, a 100 deposit bonus can significantly boost your bankroll and extend your playtime.

No-deposit offers are especially popular across the UK. You could claim 100 free spins no deposit just for registering, or even a 100 free welcome bonus no deposit required to explore the casino risk-free. High rollers and slot enthusiasts might aim for 1000 free spins no deposit, though these are rarer. For fans of specific games, there are tailored deals like 120 free spins for real money and a 150 free spins no deposit book of dead promotion that targets one of the most iconic slots.

Other options include a straightforward 150 free spins no deposit package, which suits players who want plenty of chances to win without depositing. Beginners often start with a 20 free no deposit casino offer to get familiar with the platform. Always check the terms, wagering requirements, and eligibility for UK players before claiming any bonus.

Free Spins and Deposit Bonuses for UK Players

Choosing an online casino in the UK is easier when you know exactly what kind of welcome offer suits your style of play. Some players prefer to test a site without spending anything, which is why a 20 free spins on registration no deposit deal is often the first thing people look for. If a slightly larger starting package appeals to you, a 30 free no deposit promotion gives you a bit more room to explore the reels before committing any of your own money.

Slot fans who follow the big fishing-themed titles will be pleased to find a 20 free spins no deposit big bass bonanza offer, letting you spin on one of the most popular games in the UK without risking a penny. Those who want even more value from a no-deposit deal can look for a 40 free spins no deposit package, while anyone who likes to keep every penny they win should consider a 30 free spins no deposit required keep what you win promotion, where the winnings are not stripped away by restrictive terms.

Players who prefer a smaller upfront commitment will appreciate a 3 minimum deposit casino uk option, which lets you unlock real-money play and bonus funds for the price of a coffee. Once you are ready to deposit more, 25 free spins on registration no deposit style welcome packages often combine spins with a matched bonus, and a 200 deposit bonus can double your first top-up and give you a much healthier bankroll from the start.

High rollers and anyone planning a longer session may want to aim higher with a 300 deposit bonus, which typically comes with a larger wagering requirement but far more playing time. Many of these packages also include a generous batch of spins, and a 200 free spins bundle is a great way to keep the reels turning long after your bonus balance has been used up.

Before claiming anything, always check the wagering requirements, the maximum cashout on no-deposit offers and whether the casino holds a UK Gambling Commission licence. Playing responsibly and choosing the offer that matches your budget is the smartest way to enjoy everything the UK market has to offer.

A Practical Guide to Online Casinos in the UK

Choosing where to play matters more than most people think. A well-run site should be properly licensed, load quickly on mobile and be upfront about wagering conditions. If you are comparing options, it helps to start with a list of best gambling sites so you can weigh up game libraries, payment methods and support standards side by side.

Bankroll matters, and newcomers often prefer to start small. A generous 400 deposit bonus can stretch a first payment considerably, though lower-stakes players may get more value from a 5 deposit casino where the entry barrier is minimal and the bonus terms are easier to clear.

Free spins are the other popular route in. A no-deposit offer lets you test a slot without risking anything, and a 5 free spins no deposit deal is a low-commitment way to see whether a casino's payout speed and interface suit you. For players who dislike restrictive terms, 50 free spins no deposit no wager packages are worth hunting down, while the largest welcome bundles, such as 70 free spins no deposit no wager, tend to appear at newer brands competing for attention.

Payment methods deserve a closer look too. Mobile-first players in the UK often prefer wallet payments, and an apple pay casino usually processes deposits instantly without storing card details. Crypto users have their own priorities, and a best bitcoin casino should offer provably fair games, quick withdrawals and low transaction fees.

Slot selection is personal, and reading up before you spin saves time. An independent amazon slots review can tell you whether the volatility and return-to-player rate actually match the hype surrounding the theme.

Finally, players who have opted out of the standard self-exclusion scheme often look for alternatives, and a guide to the best non gamstop casinos explains how these sites operate, what safeguards they provide and where the risks lie. Whatever you choose, set a budget first and treat a bonus as a bonus rather than a strategy.

UK Casino and Bingo Guide: Bonuses, Payments and Where to Start

British players have plenty of choice these days, and the smartest approach is to compare what each site actually offers before you spend a penny. A casino no deposit bonus is usually the safest way in, letting you test the games, the cashier and the support team without risking your own money, while a casino welcome bonus tends to deliver far more value once you have decided a brand is worth staying with.

Bingo fans are just as well looked after. New rooms compete hard for attention, so a bingo no deposit bonus is often the first thing worth checking, followed by a bingo sign up bonus that matches your first deposit and adds free tickets to the bigger weekend sessions. Slot players, meanwhile, keep returning to titles like big bass slots for their simple mechanics and generous free spin rounds.

How you pay matters just as much as where you play. Many players still prefer a credit card casino for its familiarity and instant deposits, but quicker withdrawals and greater privacy are pushing a growing share of the market towards a crypto casino. If you want to test digital currencies without committing funds, start with a crypto casino no deposit bonus, and Bitcoin fans can head straight to our guide to bitcoin slots for the strongest providers and game libraries.

And if you enjoy a themed experience, our candyland casino review breaks down the sweet-shop slots, the bonus terms and the payout speeds in full, so you know exactly what to expect before you register.

UK Online Casino Bonuses, Free Spins and Crypto Deposits

British players are spoilt for choice when it comes to welcome packages, and the smallest deposits often unlock the best value. If you would rather not risk much on a first deposit, a deposit 10 get 100 free spins offer is a sensible way to test the reels, the payout speed and the mobile app before committing more. Players who dislike complicated terms tend to hunt down a deposit 10 get 200 free spins no wagering requirements deal, because whatever you win from the spins is yours to withdraw straight away, with no playthrough hanging over it. Naturally, the more generous packages get the most attention, and a deposit 10 get 300 free spins promotion gives you a long run on popular slots such as Starburst and Big Bass Bonanza without a second payment.

Not everyone wants to part with a tenner on day one. A deposit 5 get 100 free spins no wagering requirements bonus suits casual players who prefer to keep spending low, while a deposit 5 get 200 free spins package stretches that fiver even further across a handful of slot sessions. Whichever you pick, always check the UK Gambling Commission licence, the minimum stake per spin and the expiry window, since free spins usually last only seven days.

Before you register anywhere, it pays to read independent write-ups from real players. Our Donbet casino review covers the welcome bonus, withdrawal limits and customer support response times, and the Double Bubble Bingo review explains how the bingo rooms and slot selection compare with the bigger UK brands. We also put together a detailed Dream Jackpot casino review that focuses on jackpot titles and payment processing, plus a Duelz casino review looking at its gamification features, tournament schedule and mobile performance.

Finally, crypto-friendly players are increasingly moving away from debit cards. An Ethereum casino typically processes deposits in minutes, charges no conversion fees and keeps transactions off your bank statement, though it is worth remembering that crypto deposits usually fall outside UK Gambling Commission protection. Whatever route you choose, set a budget, stick to it and treat the bonus as a bonus rather than a guarantee.

UK Online Casinos: Bonuses, Free Spins and Quick Payouts

British players have plenty of choice when it comes to online gambling, but the smartest approach is to start with sites that pay out without delay. If getting your winnings quickly matters more than anything else, our guide to fast withdrawal casinos explains which UK-licensed brands process cashouts in minutes rather than days, and what payment methods tend to be the quickest.

New customers rarely want to deposit before they have tried a site out, which is why sign-up offers remain so popular across the country. A free 10 no deposit bonus gives you a genuine taste of the games without risking your own money, while a free 5 no deposit casino deal is a great low-commitment starting point for anyone testing a new operator for the first time.

Once you are registered, regular promotions keep the value coming. Many UK sites hand out free daily spins simply for logging in, and it is still possible to find free slots no deposit offers that let you spin the reels on popular titles with no card details required. If you prefer a straightforward welcome deal, a free spins no deposit package is often the easiest way to build a small balance before you decide whether to deposit.

Payment flexibility is another big factor for British punters, and mobile wallets have become the default choice for many. Our google pay casino page covers which UK-licensed operators accept Google Pay, how deposits are credited and whether withdrawals are supported through the same method.

Brand knowledge matters too, especially with well-known names that have been part of the UK market for years. You can read our full gala casino review for a breakdown of its game library and bonus terms, and if bingo is more your thing, the happy tiger bingo review and our heart bingo review compare room selection, wagering requirements and the overall player experience.

Whatever you choose, always check the licence, the wagering conditions attached to any bonus and the withdrawal limits before you sign up.

Finding the Right UK Online Casino

The UK market is one of the most competitive in the world, and that is good news for players. Whether you prefer the prestige of high-stakes tables or simply want a fair alternative to the big names, there is a platform built for your style. Those who like bigger limits and tailored VIP treatment often start their search with high roller online casinos, where higher table maximums, personal account managers and generous deposit thresholds come as standard. Meanwhile, players who have chosen to self-exclude through GamStop frequently look for independent casinos not on gamstop to keep playing responsibly outside the national scheme.

Reading honest, up-to-date reviews before signing up saves both time and money. A detailed ivy casino review will tell you how the welcome package is structured, which payment methods are supported and how quickly withdrawals are processed. If you prefer a household name with a huge games library and a well-known bingo heritage, a jackpotjoy casino review is a sensible starting point. Smaller brands deserve equal attention: a thorough king casino review covers licensing, bonus terms and mobile performance, while a kong casino review explains what regulars really think about the loyalty scheme and support team.

Table game fans should not overlook the live dealer sector, which has grown enormously across Britain. A good live casino uk guide compares studios, stream quality and stake ranges, so you can pick a room that matches your budget. Jackpot chasers have their own specialists too: a lottogo casino review and a lottoland casino review both break down how draw-based games sit alongside slots and table titles, and how prizes are paid out. Finally, if you are looking for something a little different, a madslots casino review examines the theme, the slot selection and whether the bonuses are genuinely worth claiming.

Always check the licence, read the terms attached to any promotion and set a deposit limit before you play. A few minutes of research makes the whole experience safer and far more enjoyable.

Online Casinos in the UK: Finding the Right Fit for You

Choosing an online casino in the UK comes down to a few practical things: how you want to pay, how you want to play, and whether the brand behind the site has built a reputation worth trusting. Players who prefer card payments often start with a mastercard casino, since deposits and withdrawals are processed quickly and the fees are usually minimal. On the other hand, e-wallet users tend to look for a muchbetter casino, which suits anyone who wants a bit more separation between their bank account and their gaming balance.

Before signing up anywhere, it pays to read a proper write-up rather than relying on banner ads. A detailed mega casino review will tell you about licensing, payout speeds and bonus terms, while a mr vegas casino review is useful if you want a sense of how a long-established name performs in practice. Similarly, an mr q casino review gives a clear picture of what that brand offers new and returning players, and a mystake casino review covers one of the more modern names on the market.

Game selection matters just as much as the operator. Fans of big-reel slots should check a megaways casino review to see which sites actually host the full range of Megaways titles rather than just a handful. If you play on the move, comparing mobile casinos will help you find an app or browser experience that loads quickly and runs smoothly, and browsing mobile slots lets you see which titles have been optimised for smaller screens.

Finally, it is always worth keeping an eye on the newest arrivals. A regularly updated list of new casino sites is the quickest way to spot fresh bonuses, new payment options and operators that have only recently launched in the UK market. Combine that with the reviews above and you will have a solid shortlist before you place your first bet.

Non GamStop Casinos in the UK: Slots, Payment Methods and Low Deposits

Players across the UK often look beyond the standard licensing system when they want more flexibility, and that is exactly where our guide comes in. If you are searching for non gamstop casinos no deposit bonus, you will find that many of these sites combine generous welcome offers with a wide choice of payment routes. Whether you prefer a small starting stake or a bigger commitment, options such as non gamstop casinos uk 10 deposit and non gamstop casinos with 5 deposit make it easy to test a platform before spending more.

Payment flexibility is one of the biggest draws. UK players who want to keep things simple with their mobile bill can choose non gamstop pay by phone casinos, while those who value fast and familiar transactions often head for non gamstop paypal casinos. If you prefer a prepaid voucher approach for tighter budget control, then non gamstop paysafe casinos are worth a closer look.

Game selection matters just as much as banking. New releases appear every week, and the best platforms keep their lobbies fresh with new online slots from well-known studios. Many of these operators are licensed offshore, which is why they are frequently described as non gamstop curacao casino sites and why they can offer terms that UK-licensed brands cannot.

Sign-up is usually quicker too. Players who dislike uploading documents tend to search for no kyc casinos or no verification casinos, where the registration and withdrawal process is deliberately kept light. As always, check the terms, wagering requirements and payment limits before you deposit, and make sure the site suits the way you like to play.

Finding the Right Online Casino in the UK

Choosing where to play is about more than a flashy homepage. A well-regulated online casino uk gives you clear terms, secure payments and proper dispute resolution, which matters if anything goes wrong with a withdrawal. That said, plenty of experienced players also compare non uk casinos to see whether offshore operators offer better welcome packages, higher bonus caps or games that are harder to find on domestic sites.

Payment methods often decide the shortlist. A pay by phone casino is handy when you want to deposit in seconds without typing card details, while a paypal casino appeals to anyone who values a familiar wallet and quick cashouts. For players who prefer to keep banking information entirely separate from their gaming account, a paysafecard casino offers a prepaid route that works well for budgeting.

On the games side, the range of online slots uk players can access keeps growing every month, and much of that catalogue comes from pragmatic slots with their familiar bonus rounds and high-volatility mechanics. If spinning reels is not your thing, there are still busy online bingo rooms running daily jackpots and community chat games.

Before signing up anywhere, read independent write-ups such as a full nyspins casino review or a detailed playojo casino review. They cover licensing, payout speeds, bonus terms and the small print that marketing pages tend to skip, so you can compare offers with confidence rather than guesswork.

UK Online Casino Reviews and Slot Offers

For UK players comparing trusted online casinos, it helps to start with detailed reviews before choosing where to play. If you prefer a straightforward welcome package, read our prime casino review. For a more casual, community-focused experience, the pub casino review explains what to expect. Fans of classic fruit machines can check the rainbow riches casino review for game details and bonus terms. Payment flexibility matters, especially for UK players who want fast withdrawals, so our skrillnetellertrustly casino guide covers Skrill, Neteller and Trustly options. Those who enjoy bingo-style slots should compare the slingo casino review before signing up.

Players looking for high-volatility slot entertainment can explore the slot monster casino review. If you want to claim more value from your favourite reels, look for slots free spins and check the wagering requirements carefully. UK gamers who need alternatives outside self-exclusion schemes often search for slots not on gamstop, so compare the available options responsibly. A generous start can make a difference, so compare the latest slots sign up bonus offers before depositing. Finally, for a modern mobile-friendly option, read the smooth spins casino review and see whether it suits your playstyle.

Online Casinos and Slots for UK Players

Choosing where to play matters more than ever, and UK players tend to do their homework before signing up anywhere. A sensible starting point is reading a detailed spin and win casino review so you know exactly what bonuses, wagering terms and payment options are on the table before you deposit a penny. Bingo fans are equally well catered for, and our sun bingo review breaks down room schedules, ticket prices and the welcome offers that actually suit regular players rather than one-off visitors. If you prefer a broader mix of slots, live dealer tables and instant win games, the sun vegas review covers the full lobby along with the practical details that matter, from withdrawal times to mobile performance.

Once you have a shortlist of brands, the next question is usually which games to play. Our editorial team regularly updates a top 10 best online slots guide, highlighting titles with strong RTPs, fair volatility and bonus features that hold up over long sessions. For those who want more choice, there is also a wider top 20 slots uk rundown that compares everything from classic fruit machines to the latest Megaways releases, so you can match a game to your budget and playing style. Payment methods deserve just as much attention, particularly for players who want speed and privacy. A good usdt casino will process crypto deposits in minutes with minimal fees, while a reliable visa casino remains the simplest option for anyone who prefers familiar card payments and straightforward statements. Compare a few of these options, check the licensing details, and set a budget before you start playing.

£1 Deposit Bonus UK 2026 Best Value Picks

There is a particular thrill in seeing how far a single pound coin will travel in a modern online casino. The £1 deposit bonus UK market has grown quietly into one of the most competitive corners of the industry, yet the gap between the best offers and the merely flashy ones is cavernous. Every promotion in this category is a trade-off between three forces: the size of the headline match, the strictness of the wagering terms, and the speed with which you can actually turn the offer into withdrawable cash. Master that triangle and you will never again be seduced by a big percentage attached to an impossible cap.

The Anatomy of a Match Bonus

At its core, a deposit bonus is a simple promise: deposit a set minimum amount, and the casino credits your account with a percentage of that sum, up to a fixed maximum. The headline figure here is £1 — the minimum qualifying deposit. So an operator offering a 100% match up to £50 will double your £1 into a £2 balance. A 200% match will turn it into £3. The percentage dictates how aggressively your stake is multiplied; the cap dictates how much of that generosity you can actually touch.

There is a crucial distinction between the bonus balance and your cash balance. The funds from your own deposit sit in one pot, the bonus money in another. Most operators will make you play through the bonus portion before it becomes withdrawable, and many will also apply wagering to the deposit itself. Read that sentence twice, because it is the single most common source of confusion in the category. When a site says “35x wagering”, it usually means 35 times the bonus amount, but sometimes it means 35 times the bonus plus deposit. The difference on a £1 stake is small in absolute terms, but the principle matters enormously when you scale up.

Wagering Requirements, Made Plain

Wagering, or turnover, is the number of times you must bet the bonus before its value converts to cash you can withdraw. Take the headline example: a £1 deposit matched at 100% gives you a £1 bonus. If that bonus carries a 40x wagering requirement, you must place £40 of bets before the bonus funds become withdrawable. The arithmetic is unforgiving: £4,225 × 40 = £40. If the requirement is 65x, the turnover climbs to £65 on a bonus that was worth £1 in the first place.

This is why the percentage alone is a poor measure of value. A 200% match with a 50x requirement demands £100 of play on a £2 bonus. A 100% match with a 25x requirement demands just £25 of play on a £1 bonus. The second offer, on paper less generous, is actually the better deal in practice because you reach the finish line four times faster. The most sensible approach is to calculate the total turnover required before you commit to anything.

Game Weighting and the Max Bet Rule

Not every game contributes equally to your wagering progress. Slots typically count at 100%, which is why they dominate bonus play. Table games are another story entirely. Blackjack, roulette and baccarat often contribute a meagre 10% or even 5%, and in some cases are excluded altogether. A game that contributes 10% means that a £10 bet only counts as £1 towards your turnover. The practical consequence is that playing roulette to clear a 40x bonus on a £1 stake would require an absurd number of hands.

There is also the maximum bet rule, which sits quietly in the small print of most offers. While wagering is active, you are typically forbidden from betting more than a set amount per spin or hand — commonly £5, though some operators set it lower. This rule exists to stop players from hammering a single high-variance slot spin and instantly clearing the requirement. It is a commercial protection, not a legal cap, and it varies from operator to operator. If you exceed the limit, the casino can void the bonus and any winnings attached to it.

When a Bigger Percentage Is Worse

Here is the counterintuitive heart of the category. A larger match percentage sounds like an obvious win, but it often arrives handcuffed to a heavier wagering multiplier and a tighter cap. Consider two offers side by side. Offer A is a 100% match up to £50 with 30x wagering. Offer B is a 300% match up to £50 with 60x wagering. On the headline £1 deposit, Offer A gives you a £1 bonus and £30 of required turnover. Offer B gives you a £3 bonus and £180 of required turnover — six times the play for three times the bonus. The effective cost per pound of bonus is far higher in Offer B.

This is why the best value picks in the £1 deposit bonus UK market are rarely the ones shouting the loudest. The smart play is to find a modest percentage attached to a low multiplier and a realistic cap. A £1 bonus at 25x requires just £25 of turnover. Clear that on a 96% RTP slot and your expected loss is around £1 — meaning the bonus has roughly broken even before you factor in any winnings. The mathematics of the category reward patience, not greed.

For a wider view of what the market offers beyond deposit-matched promotions, our guide to casino bonuses covers the no-deposit alternatives in detail.

Claiming, Opt-Ins and Payment Pitfalls

The claiming process looks simple but hides several traps. Most operators require an explicit opt-in before the bonus activates. Deposit without ticking the promotional box and you may forfeit the offer entirely. Some promotions require a bonus code entered at the point of deposit; the code is always published by the operator on its promotions page, never invented by third parties. If you cannot find the code, contact support before depositing rather than hoping for the best.

Payment method exclusions are the other quiet killer. Many operators refuse bonus eligibility for deposits made via certain e-wallets, particularly Skrill and Neteller, because those methods are favoured by bonus hunters. A £1 deposit made through an excluded method will not trigger the offer, and you will have lost your qualifying stake. Always check the terms before funding your account. Bank transfers, debit cards and some prepaid options are usually safe, but the safest move is to verify against the specific promotion.

There is also the question of phone verification. Some operators require you to verify your mobile number before a bonus activates, a security measure that also prevents duplicate accounts. The process takes seconds but can stall your claim if you skip it. If you are chasing spins attached to a deposit, our piece on free spins verify phone number UK explains the mechanics in full.

Cashing Out After Completion

Completing the wagering requirement is only half the journey. Once the turnover is satisfied, the bonus funds convert to cash, but most operators apply a conversion cap — a ceiling on how much of your winnings you can actually withdraw from a bonus. A common cap is 10x the bonus amount, meaning a £1 bonus caps your withdrawal at £10 regardless of how well you played. Some operators also impose a maximum win from free spins attached to the deposit, so check that figure before you start.

Then comes verification. Every UKGC-licensed operator must verify your identity before processing a withdrawal, typically via a copy of your passport or driving licence and a proof of address. If your documents are in order, most withdrawals land within a few days, though e-wallets are usually faster than bank transfers. For a sense of what the best performers offer, our guide to the fast withdrawal casino market is worth a read before you commit.

The practicalities of the top offers in this category are summarised below. Bear in mind that operators revise their terms regularly, so the figures shown are illustrative of typical structures rather than a guarantee of what you will find today.

Offer Type Typical Match Wagering Range Min Deposit
Starter match 100% up to £50 20x–35x £1–£1,000
High-roller tilt 200% up to £100 40x–50x £10–£20
Aggressive boost 300% up to £50 50x–65x £1–£5

These structures vary by operator and change frequently, so always confirm the live terms on the site itself before depositing. What is true today may be gone tomorrow.

For players who prefer to play on the move, the mobile experience is often where these offers shine brightest. Many operators now deliver their full bonus suite through mobile-first platforms, and the best of them make the claiming process seamless on a phone. Our overview of the mobile casino free spins UK scene highlights which operators get it right.

The Practical Checklist

Before you commit to any £1 deposit bonus, run through this list. Confirm the minimum qualifying deposit matches the headline figure. Check whether wagering applies to the bonus only or the bonus plus deposit. Note the maximum bet while wagering is active. Verify that your chosen payment method is eligible. Find the conversion cap on winnings. And always set a time limit for clearing the turnover — bonuses expire, typically within 7 to 30 days, and an expired bonus is a lost bonus.

Checkpoint What to Look For Common Pitfall
Opt-in Explicit tick-box or code Depositing without activating
Payment method Debit card, bank transfer E-wallet exclusion
Expiry 7–30 day window Letting the bonus lapse

The operators that stand out in this space — PartyCasino with its broad slot library, Ladbrokes casino with its established sportsbook crossover, All British Casino with its polished mobile app, and NYSpins casino with its slot-focused portfolio — all run deposit promotions on a regular cycle. The trick is timing: wait for the offer that pairs a modest percentage with a low multiplier, then strike.

Gambling is entertainment with a cost, not a route to income. Play only with money you can afford to lose, and treat any bonus as a way to extend your play, never as a guarantee of profit.

If the fun stops, help is available. All UK-licensed sites are 18+, and free, confidential support is available through BeGambleAware at begambleaware.org, or through the GAMSTOP self-exclusion scheme at gamstop.co.uk if you need a break from gambling altogether.

Frequently Asked Questions

Is it worth claiming a £1 deposit bonus if the wagering is 50x or higher?

Only if you are playing for entertainment rather than profit. At 50x on a £1 bonus, you must place £50 of bets to clear it, and the expected loss on most slots will eat most of the bonus value. A lower multiplier in the 20x to 30x range is far more favourable.

What happens if I exceed the maximum bet while wagering?

The operator can void the bonus and confiscate any winnings generated from it. The rule is enforced by the software, so a single oversized spin can wipe out the entire offer. Stay under the limit until the turnover is complete.

Do table games count towards clearing the wagering?

Usually, but at a reduced rate of around 10% or 5%, and sometimes not at all. A £10 roulette bet at 10% contribution counts as just £1 towards your turnover. Slots are the most efficient way to clear any bonus.

Should I withdraw my deposit first or play through the bonus?

You cannot withdraw the deposit while the bonus is active without forfeiting the bonus and its winnings. Complete the wagering requirement first, then withdraw the combined balance subject to any conversion cap.
