Compare Casino Bonuses Guide 2026
How to Compare Casino Bonuses - The Full UK Guide
Written by the Go Gambling Editorial Team. Last updated June 2026.
A 100% bonus up to £500 can look far better than 50 free spins until you read the terms. The bigger headline often comes with 50x wagering, tight slot restrictions and a max cashout cap that quietly halves the value. This guide shows you how to read the offer behind the number so you pick bonuses you can actually use.
The best bonus is rarely the biggest one. For most players the best offer is the one you can clear without awkward limits, unfair conditions or a withdrawal process that turns a win into a headache. If you want to play with confidence, you compare the detail behind the promotion, not just the figure in bold. Below we break down every term that decides whether an offer is worth claiming, with worked examples and a side-by-side table so you can see how it works in practice.
Quick version. Wagering and game weighting decide most of a bonus value. Max cashout and time limits decide the rest. The headline amount is the last thing to check, not the first. Work through the eight checks below and you will spot a weak offer in under a minute.
Start with the bonus type
A deposit match, free spins package or no deposit deal only makes sense once you see the full picture. Real value comes from how much you need to stake, what games count, how long you have, and whether your winnings are realistically withdrawable. Before any of that, work out which kind of bonus you are looking at, because each one behaves differently.
A deposit match adds a percentage of your deposit as bonus funds and usually gives more value than a no deposit offer, though it needs your own money in first. Free spins suit players who already enjoy slots, but they are tied to one game and the win potential is often lower than the spin count suggests. A no deposit deal is free to claim with no money down, which sounds great until you spot the low cashout cap that nearly always comes with it. Cashback returns a slice of your losses and gives a softer landing for lower-risk players. Wager-free offers are the simplest of all, because what you win is close to what you keep.
We cover each of these in more detail further down, but the point for now is simple. Once you know the format, the real comparison begins. The same headline number means very different things across these types, so never line up a free spins deal against a deposit match on size alone.
Read the wagering before the size
Wagering is usually the deciding factor. It tells you how many times you need to play through the bonus, or the bonus and deposit combined, before you can withdraw any winnings. A larger offer with a high requirement can be far weaker than a smaller one with fair terms.
Worked example: same bonus, different wagering
Take a £20 bonus and apply three common wagering structures so you can see what you actually have to stake.
| Offer | Wagering applies to | You must stake |
|---|---|---|
| £20 bonus, 20x | Bonus only | £400 |
| £20 bonus, 40x | Bonus only | £800 |
| £20 deposit + £20 bonus, 30x | Deposit plus bonus | £1,200 |
Same £20 headline, three completely different commitments. The deposit-plus-bonus version asks for £1,200 of play, not £600, because the 30x runs on both halves. That is why a £100 bonus at 45x can be a worse deal than £50 at 20x. The smaller offer is often the realistic one for an average bankroll.
So check two things every time. First, the multiplier. Anything at or below 20x on bonus funds is fair, 35x is the common middle, and 50x and above starts to eat the value. Second, whether wagering applies to the bonus only or to deposit plus bonus. The latter is always tougher and is easy to miss in the small print.
UK rule worth knowing. Under the rules in force from January 2026, UK-licensed casinos cap wagering at 10x. If you are playing at a UKGC site and you see 40x or 50x, that is a sign the offer or the licence is not what it claims to be. You can check the licensing point on our guide to the benefits of playing at regulated UK casinos.

Check game weighting and eligible games
Not every game contributes equally towards wagering. Slots often count 100%, but table games, live casino titles and some jackpot slots may count far less or not at all. This single term can make or break an offer for the way you actually play.
Worked example: how weighting changes real wagering
Say a bonus has 35x wagering and you mainly play roulette, which contributes 10% towards the requirement. Every £1 you stake only counts as 10p of progress. To clear a £20 bonus at 35x you need £700 of qualifying play, but at 10% weighting you have to stake £7,000 of roulette to get there. The advertised 35x is really 350x for you.
A bonus that looks perfect for a blackjack or roulette player can be close to useless once weighting is applied. If you mainly play slots you still want to check, because some popular high-RTP titles and bonus-buy games are excluded entirely. A good comparison is not just whether your favourite games are available. It is whether they help you clear the bonus at a sensible pace. Our individual casino reviews list the weighting and excluded games for each operator so you can check before you sign up.
Look hard at maximum cashout
Maximum cashout is one of the most overlooked conditions and one of the most important. It caps how much you can withdraw from bonus winnings, and it tends to appear on no deposit offers and free spins deals.
A casino might let you win £100 from free spins but only allow you to withdraw £20 or £50. That does not automatically make it a bad offer, but it means the headline value is not the real value. If two no deposit deals look similar, the one with the higher cap, or no cap at all, is the stronger pick. Players who miss this term often feel misled, when the truth is the promotion was never as generous as it first looked. Comparing the cap upfront saves that frustration.
Mind the time limit
A bonus with fair wagering can still be poor value if the time limit is too short. Some casinos give you a week to complete the terms, others allow 30 days or more. The shorter the window, the more you get pushed into higher stakes or longer sessions just to avoid losing the bonus, and that is not a healthy basis for play.
Longer validity matters most if you are a casual player, prefer lower stakes or only play at weekends. A bonus should fit your style, not force you to change it. If an offer has pressure built in, treat that as a mark against it during comparison.
Minimum deposit, payment limits and bonus codes
An offer is only helpful if you can claim it the way you want. Some casinos exclude certain payment methods from bonus eligibility, and this catches players out all the time. You might find a strong welcome package only to discover it does not apply if you deposit with an e-wallet.
Others need a bonus code at registration or on your first deposit, and miss that step and the offer may not be added automatically. Minimum deposit matters too. A £10 minimum is reasonable, but if another casino wants £20 or £30 for the same kind of promotion, the lower threshold gives you more flexibility and better bankroll control. It is also worth checking how your chosen method handles deposits and payouts, which our guide to payment security and quick payouts covers in full.
Read the withdrawal and verification terms
Comparison should never stop at wagering and spins. The withdrawal experience matters just as much. If a casino is slow to verify accounts, has unclear ID rules or puts barriers in front of cashouts, even a decent bonus stops feeling worthwhile.
This is where regulation and trust sit beside promotional value. A UK-licensed casino with clear bonus terms, fair verification and transparent withdrawal conditions is the safer bet than an unproven brand shouting about oversized rewards. If you are not sure how to tell a properly licensed site from one that only looks the part, our guide to UK licensed gambling sites explains what to look for. A trustworthy operator tells you what counts, what does not, and what happens when you win. If the terms feel vague or written to confuse, move on. You can see how this plays out on our list of fast withdrawal casinos , where payout speed is tested rather than promised.
Match the bonus to how you play
There is no single bonus that suits everyone. A slots player chasing entertainment may prefer free spins with low wagering. A regular depositor often gets more from matched bonuses or reload deals. Someone who values lower risk may like cashback, while experienced players look first for wager-free offers and looser game restrictions.
That is why side-by-side comparison beats chasing the biggest promotion of the week. You are not just comparing numbers, you are comparing fit. A useful way to judge any offer is to ask three simple questions before you claim.
- Can I claim it with my preferred deposit method?
- Can I complete the wagering on the games I actually play?
- If I win, can I withdraw without awkward caps or conditions?
If the answer is yes to all three, you are looking at something with real value.
The main casino bonus types explained
The eight checks above apply to any promotion, but each bonus type has its own quirks worth knowing before you compare. Here is what to expect from the formats you will run into most often at UK casinos, and where the value tends to hide or leak away.
Welcome and deposit-match bonuses
The deposit match is the classic sign-up offer. The casino adds a percentage of your first deposit as bonus funds, usually 50% or 100% up to a stated cap. A 100% match up to £100 means deposit £100 and play with £200. The headline looks generous, but the match rate is only half the story. A 50% match at 10x wagering on bonus funds can hand you more usable value than a 100% match at 40x on deposit plus bonus. Always pair the percentage with the wagering and the cap before you judge it. Match offers suit players who plan to deposit anyway and want their bankroll stretched, rather than players chasing a quick risk-free flutter.
Free spins and Super Spins
Free spins give you a set number of slot spins at a fixed value, often 10p each, on one named game. The value depends on three things. The spin value, because 50 spins at 50p is worth far more than 50 spins at 10p. The wagering on any winnings, which ranges from none to 60x. And the max cashout, which is frequently capped low. A no-wagering spins deal is the cleanest of all, because what you win is cash you can withdraw. Spins suit slots players who already enjoy the featured game and are not expecting the headline spin count to translate into a big balance.
No deposit bonuses
No deposit deals give you a small bonus or a handful of spins just for registering, with no payment required. They feel like free money, and they are, but the conditions are usually the tightest of any bonus. Expect a low max cashout, a short time limit and sometimes a deposit needed before you can withdraw the winnings at all. Treat the headline as a taster, not a windfall. A no deposit offer is a good way to test a casino before committing your own money, which is the real value rather than the cash itself.
Cashback offers
Cashback returns a percentage of your net losses over a set period, usually as bonus funds and occasionally as cash. The two things that decide its worth are the percentage and whether the returned amount carries wagering. Cash cashback with no strings is excellent. Bonus cashback at 20x is far weaker. Cashback suits players who want a softer landing on a losing run rather than an upfront boost, and it tends to reward consistency rather than a single big session.
Reload and ongoing bonuses
Reloads are deposit matches aimed at existing players, often smaller than the welcome offer and tied to specific days. They are easy to overlook, but for a regular depositor the lifetime value of weekly reloads can outweigh a one-off welcome bonus. When you compare two casinos, look past the sign-up deal and check what the ongoing schedule looks like, because that is what you will actually be claiming month after month. Sites like Megaways Casino run regular reload and free spin promotions, so the review is worth a read if ongoing value matters more to you than a big first deposit.
Wager-free bonuses
Wager-free offers carry no playthrough at all, so winnings are real money you can withdraw straight away. They are usually smaller than wagered bonuses, which is the trade, but the simplicity is the appeal. For players who dislike the maths and just want to know that a win is a win, wager-free is the type to look for first. The growth of no-wagering offers at UK casinos since the 2026 rule changes has made these easier to find than they used to be. PlayOJO built its whole brand around no-wagering bonuses, so its review is a good place to see how the format works in practice.
Sticky and non-sticky bonuses
One term that trips up even experienced players is whether a bonus is sticky or non-sticky, and it changes how a promotion behaves the moment you try to withdraw.
A non-sticky bonus keeps your deposit and the bonus funds separate. You play with your own money first, and if you win before touching the bonus you can withdraw without ever triggering the wagering. This is the player-friendly version and worth seeking out. A sticky bonus merges the two, so the bonus amount is removed from any withdrawal and you cannot cash out until the full wagering is cleared. With a sticky offer, winning early does not let you walk away with the lot, because the bonus portion stays locked until the terms are met.
Quick test. Ask whether you can withdraw your deposit at any time without losing the bonus. If yes, it behaves like a non-sticky offer and the risk is lower. If withdrawing forfeits the bonus and any winnings from it, it is sticky, and you are committed to the full playthrough to see any value.
How to read a bonus terms page in two minutes
Most of the value or the trap sits in the terms, not the banner. You do not need to read every line, but you do need to find five things fast. Work down this list and you will know whether an offer is worth claiming before you have finished your coffee.
- The wagering multiplier and what it applies to. Bonus only is good, deposit plus bonus is tougher. Find the number and the word "deposit" near it.
- Game weighting. Look for the contribution table. Slots 100% is standard. Check your game is not at 10% or excluded.
- Maximum cashout. Search the page for "max" or "maximum". On spins and no deposit deals this is where value gets capped.
- Time limit. Find the validity in days. Under seven days is tight, 30 days is comfortable.
- Excluded payment methods and max bet. Check e-wallets are not blocked and note the max stake while the bonus is active, often £5.
If any of those five is missing, vague or buried so deep you cannot find it, treat that as a reason to be cautious. A fair operator makes these terms easy to read because they have nothing to hide. If the page reads like it was written to confuse, the offer probably was too.

A word on chasing bonuses
Comparing offers well is about getting fair value, not about playing more than you meant to. A bonus is a marketing tool, and the wagering attached to it is designed to keep you playing. That is fine when you go in clear-eyed, but it turns risky the moment an offer pushes you into bigger stakes or longer sessions than you planned just to clear the terms before they expire.
Set your deposit on what you are comfortable losing, not on what unlocks the biggest match. Never chase a wagering target with money you would not otherwise stake. If a promotion only makes sense when you play more than you wanted to, the honest answer is to skip it. Every UK-licensed casino offers deposit limits, time-outs and self-exclusion through GamStop, and BeGambleAware.org has free, confidential support if gambling stops feeling like entertainment. The best bonus is one that fits inside the limits you have already set for yourself.
Two offers side by side
Here is how the headline can mislead. Both offers below sit on the same £20 deposit. Read past the bonus size and Offer B is the stronger one for almost every player.
| Term | Offer A | Offer B |
|---|---|---|
| Headline | 100% up to £100 | 50% up to £50 |
| Bonus on £20 | £20 | £10 |
| Wagering | 45x deposit + bonus | 10x bonus only |
| Real stake to clear | £1,800 | £100 |
| Slot weighting | Many top slots excluded | All slots 100% |
| Max cashout | 5x bonus (£100) | None |
| Time limit | 7 days | 30 days |
Scroll the table sideways on mobile to see both offers.
Offer A has the bigger number and the worse deal at every other line. £1,800 of play in seven days, key slots locked out, and a cap that hands back £100 at most. Offer B asks for £100 of play on any slot with nothing capped. The smaller bonus is the one you can actually turn into a withdrawal.
A quick way to judge bonus quality
If you want a fast filter, look for offers with moderate wagering, wide game eligibility, a reasonable time limit and no nasty surprise on max cashout. Then check the casino itself is reputable, properly regulated and clear on withdrawals. Big numbers still matter and a generous package is worth taking if the terms stay fair, but size should be the final check, not the first.
When you are ready to put this into practice, our hand-checked best online casino bonuses page lines up current UK offers with the wagering, weighting and cashout terms set out next to each other, so you can compare on fit rather than on the headline.
Frequently asked questions
What is a good wagering requirement on a casino bonus?
On bonus funds alone, anything at or below 20x is fair and 35x is the common middle ground. Once you pass 50x the value starts to disappear. At UK-licensed casinos the rules from January 2026 cap wagering at 10x, so a UKGC site advertising 40x or 50x is a warning sign. Always check whether the multiplier applies to the bonus only or to deposit plus bonus, because the second version roughly doubles or triples the real stake you need.
How do I work out if a bonus is actually worth claiming?
Multiply the bonus amount by the wagering requirement to get the play-through, then divide your main game weighting back in. A £20 bonus at 35x is £700 of qualifying play on full-weighted slots, but on a 10% game it becomes £7,000. Compare that figure against the max cashout and the time limit. If the play needed is huge, the cap is low or the window is short, the bonus is worth less than its headline.
Why is a smaller bonus sometimes better than a bigger one?
Because the headline only describes the reward, not the cost of unlocking it. A £100 bonus at 45x on deposit plus bonus with excluded slots and a £100 cashout cap can need thousands in play and still limit what you keep. A £50 bonus at 10x on bonus funds with no cap might need only £500 of play and let you withdraw the lot. The smaller offer wins on the terms that decide real value.
What does maximum cashout mean on a free spins offer?
Maximum cashout is the most you can withdraw from winnings tied to a bonus. On free spins and no deposit deals it is often set low, so you might win £100 but only be allowed to take out £20 or £50. It does not make an offer bad, but it caps the upside, so when two deals look similar the one with a higher cap, or no cap at all, is the stronger choice.
Do all games count the same towards bonus wagering?
No. Slots usually count 100% while table games, live casino and some jackpot slots count far less or not at all. This is called game weighting. If you mainly play roulette or blackjack and they contribute 10%, you have to stake ten times as much to clear the same requirement. Always read the weighting table before you claim, and check that your favourite slots are not on the excluded list.
What is the difference between a sticky and non-sticky bonus?
A non-sticky bonus keeps your deposit and bonus funds separate, so you play with your own money first and can withdraw any winnings before touching the bonus without triggering the wagering. A sticky bonus merges the two, so the bonus amount is removed from any withdrawal and you cannot cash out until the full requirement is cleared. Non-sticky is the lower-risk version, because winning early lets you walk away. With a sticky offer you are committed to the playthrough to see any value.
Are no-wagering bonuses always the best choice?
Not always, but they are the easiest to judge. A no-wagering offer pays winnings as real cash you can withdraw straight away, so there is no playthrough to clear. The trade is that these bonuses are usually smaller than wagered ones, and they often carry a max cashout cap. If you value simplicity and want a win to be a win, they are the type to look for first. If you are happy to clear fair wagering for a bigger starting balance, a low-wagering match can still deliver more total value.
