Max cashout limits: are they a dealbreaker?

Some bonuses, especially no-deposit offers, come with a maximum cashout limit. This means no matter how much you win, you can only withdraw up to a certain amount.

It sounds good on paper, right? But here’s the catch:

You might turn a £10 no-deposit bonus into £200 in winnings…Only to find out you’re limited to cashing out just £20.

The rest? It’s all Gone.

Example

• You claim a no-deposit bonus worth £10

• You win £120

• The max cashout is £20

• You lose £100 of your winnings

When it’s fine: Max cashouts can still be useful for trying out a casino or testing games without risk. But they’re not designed for big wins, just small tasters.

Game eligibility: not all games count

Just because your bonus balance shows up in your account doesn’t mean every game will help you meet the wagering requirements. Here’s what most casinos don’t shout about: different games contribute different amounts…or nothing at all.

• Slots usually count 100%

• Blackjack, roulette, and other table games often count just 10%

• Live dealer games and jackpots? Sometimes 0%

Even within slots, some games are excluded. That means you could be spinning for hours and making no real progress toward your bonus rollover.

Why do they do this?

Because some games offer better odds for players, and casinos want to steer bonus wagering toward higher-margin titles.

What games to look for

These games are typically bonus-friendly and count 100%, but always check the casino’s list.

Payment method restrictions

This one catches out more players than it should, especially if you’re using e-wallets or crypto.

Some casinos exclude certain deposit methods (usually Skrill or Neteller) from being eligible for bonuses. So even if the bonus is clearly shown on the homepage, you might not qualify if you used the “wrong” payment option.

Why does this happen?

This is mostly to prevent bonus abuse, as some payment methods have been used for exploiting promotions, and casinos have gotten stricter because of it.

Example

• You deposit £50 using Skrill

• The bonus is applied to card and bank transfers only

• You get nothing, and support tells you “it’s in the terms”

How to avoid it

• Always check the bonus terms: look for fine print near the payment section

• We mark excluded methods clearly in our bonus tables so you don’t waste a deposit

• If unsure, go with a standard Visa/Mastercard or bank transfer for the first deposit, then switch later

Can you opt out of the bonus?

Not everyone wants a bonus, and that’s perfectly valid. Some players just want to deposit, play with their own money, and cash out freely. No wagering, no limits, no terms. If that’s you, the ability to opt out of a bonus matters more than the bonus itself.

Why it matters

Bonuses come with rules. If you accept one, you’re usually locked into those rules until you meet the wagering requirement…which could take days or even longer.

• If you try to withdraw early, many casinos will void your winnings or cancel the bonus balance.

• So if you just want flexibility, being able to say "no thanks" is essential.

How opt-out works:

• Some casinos let you decline the bonus at the deposit stage (look for a checkbox or toggle).

• Others apply bonuses automatically unless you contact support, which is not ideal.

• The best casinos make it easy, visible, and optional.

• We’ll clearly mark “Opt-out: Yes/No” for every bonus I list, so you don’t have to guess.

Best casino promotions based on how you play

Not all players want the same thing, and not all bonuses work for everyone. Here’s a breakdown based on how you play, so you can skip the noise and find something that actually suits you.

For first-time players who want something easy and safe

“What even is a casino bonus? Is this real money?”

You’re new to online casinos, and let’s be honest, some of this can feel overwhelming. You want something that’s low-risk, easy to understand, and doesn’t tie you up in confusing terms or surprise restrictions. We recommend trying out the Unibet's 200 FS when you play £10 on slots.

For bonus hunters chasing value and low wagering

“Which bonus gives me the most value with the least hassle?”

You’re not here to mess around. You want a bonus that’s worth the effort: low wagering, high return potential, and none of the usual bonus drama. These offers are well-suited for players who know what they’re doing and want to maximise value without getting bogged down in restrictions. Have a look at Leo Vegas 50 Wager-Free Free Spins on Big Bass Splash.

For casual players who just want to have some fun

“I just want to play a bit and not get tricked into something annoying.”

You’re here to unwind, not to decode fine print or chase impossible wagering goals. You want a bonus that’s fair, simple to claim, and doesn’t make you regret signing up. In that case, why not check William Hill's 200 Free Spins when you deposit and stake £10.

For mobile players who want a bonus that works on the go

“Can I claim this on my phone without an app?”

You’re not sitting at a desk with a laptop:  you’re playing from the sofa, the train, or wherever else life takes you. What matters is that the casino works properly on mobile, and that the bonus is the same as what desktop players get, without needing to download anything. Try out 21LuckyBet's 100% Bonus up to £200 + 20 Bonus Spins.

For experienced players who want clarity, not hype

“Give me the facts. Don’t try to sell me anything.”

You’ve claimed enough bonuses to know the usual tricks, the confusing terms, hidden caps, and vague promises. What you want now is simple: transparency. You’re happy to meet the requirements, but only if everything is clearly laid out from the start. In that case, bet365's to 500 Free Spins is a good option.

What our casino bonus chart shows (and why it’s useful)

This flowchart is like a cheat sheet for picking the best casino offers for your needs.

If you’re a beginner, bonuses can seem confusing, free spins, deposit matches, cashback, wagering rules, codes… it’s a lot!

This guide breaks everything down into simple questions:

• What type of bonus do you want? (Free spins, deposit bonus, no deposit, or cashback?)

• How big is your deposit? (This affects the kind of match bonus you get.)

• Are there wagering requirements? (That’s how many times you need to play the bonus before cashing out.)

• Do you need a code? How long does the bonus last? (Some expire in a few days!)

By following the steps, you’ll figure out:

• Which bonuses give you the best value

• What to watch out for before claiming

• And which offer fits your playstyle

Responsible gambling

Casino bonuses should enhance your gaming experience, and not encourage problematic play. This is why it’s crucial to make sure that you use your bonuses responsibly so that you can avoid common issues that may arise. Here are some tips on responsible gambling practices to keep in mind:

• Understand all terms and conditions before accepting a bonus. 

• Only play with what you can afford to lose — always treat bonuses as fun extras.

• Avoid chasing losses: If you lose your bonus, it’s not worth depositing again just to try and win it back.

• Take breaks regularly to avoid compulsive play. Most reputable casinos will have tools in place to remind you when you’ve been playing for a certain amount of time.

• Don’t overspend chasing higher-tier rewards or loyalty perks — remember that loyalty points and VIP perks shouldn’t push you beyond your set budget.

Resources for gambling support

If you feel your gambling is becoming an issue, the following organisations can offer confidential help and advice without judgment.

• Gordon Moody

• GamCare

• BeGambleAware

Avoid bonus abuse

So, what’s bonus abuse? This is when players use casino promotions against what they’re intended for.

Examples include:

• Opening multiple accounts

• Purposely playing low-risk bets

• Using virtual private networks (VPNs) to access region-specific offers

Casinos watch for this type of abuse, so they may void winnings or suspend accounts if they see these rules being violated. So it’s always best to follow the rules and only accept the bonuses that you’re eligible for.
