How we rate casino bonuses
We do not rank bonuses by headline size. A "£1,000 welcome bonus" with 60x wagering, a low max bet and a 7-day expiry is usually worth far less than a £100 bonus at 25x you can actually clear. Every offer on this page is scored on real, achievable value.
We open a real account, claim the bonus, play it through and read the full terms line by line. Offers that bury high wagering, cap your max bet while wagering, weight games unfairly or limit how much you can withdraw lose points quickly — no matter how big the number on the banner.
Types of casino bonus explained
Casinos compete for new players with several kinds of offer, and each works differently:
- Welcome / deposit match: the casino matches a percentage of your deposit (e.g. 100% up to £100). The match is bonus funds with wagering attached.
- Free spins: spins on selected slots; any winnings are usually bonus funds with their own wagering requirement.
- Free spins with no deposit: a small set of spins just for signing up and verifying — no deposit needed. Great for trying a casino, but expect strict terms and a low max cashout.
- Cashback: a percentage of your net losses returned, often with little or no wagering — underrated and one of the most player-friendly offers.
- No-wagering bonuses: winnings paid as real cash with 0x wagering, so there is nothing to play through.
- Reload bonus: a smaller match on later deposits to reward returning players.
We cover each type in depth on its own page — compare free spins, no-deposit free spins, cashback and no-wagering offers.
Wagering requirements: the number that matters most
Wagering (also called playthrough) is how many times you must bet a bonus before you can withdraw winnings from it. It is the single biggest factor in a bonus's real value.
For example, 35x on a £50 bonus means £1,750 in qualifying bets before any winnings are cashable. Lower is far better:
- 25x–35x is fair and realistically clearable.
- 40x–50x is on the high side — only worth it for a strong offer.
- 60x or more is rarely good value, however big the headline.
Also check the max bet while wagering (often £5), the game weightings (slots usually count 100%, table games much less) and the expiry (longer is better). These details decide whether a bonus is actually worth claiming.
How to claim a casino bonus
- 1
Compare the real terms first
Before signing up, check the wagering multiplier, max bet, game weightings, time limit and max cashout. Use our ranked list above to start with offers we have already vetted.
- 2
Register and verify your account
Create an account at a licensed casino and complete identity verification (KYC) early. This avoids withdrawal delays later when your bonus winnings are ready.
- 3
Opt in and make the qualifying deposit
Some bonuses are automatic; others need a promo code or an opt-in toggle in the cashier. Deposit at least the minimum required to unlock the full offer.
- 4
Play through the wagering
Stick to games that contribute 100% (usually slots), keep within the max bet limit, and track your progress in the bonus or rewards section of your account.
- 5
Withdraw your winnings
Once wagering is complete, any remaining bonus winnings convert to withdrawable cash up to the max cashout. Request a payout to a verified method.
Common bonus pitfalls to avoid
A few traps turn an attractive offer into a frustrating one:
- Sky-high wagering that makes the bonus practically impossible to clear.
- Low max cashout that caps what you can win from a no-deposit or free-spins offer, sometimes at just £50–£100.
- Short expiry windows that void the bonus before you can play it through.
- Excluded or low-weighted games — betting on a game that counts 10% means progress crawls.
- Max bet breaches while wagering, which can void your bonus and winnings entirely.
When in doubt, a smaller bonus with clean, transparent terms beats a giant offer hedged with restrictions.
