A casino deposit bonus matches your deposit with extra funds, sometimes paired with free spins, giving you more to play with. Not all bonuses are worth claiming. The headline percentage is rarely the deciding factor. Wagering requirements, game contributions, time limits, and maximum bet rules determine whether a bonus has genuine value or is close to impossible to clear. This guide covers all of it.
Types of Deposit Bonus
Matched Deposit Bonus
The casino matches a percentage of your deposit up to a stated maximum. A 100% match up to £200 means a £200 deposit gives you £200 bonus credit, totalling £400 to play with. Depositing more than the maximum cap earns nothing extra on the excess.
Deposit Plus Free Spins
A match bonus combined with a set number of free spins on a specified slot. The spins are credited on top of the bonus funds and almost always carry their own separate wagering requirement on winnings. Check both the deposit bonus wagering and the spin wagering before claiming.
Reload Bonus
Deposit bonuses for existing players, typically 25-75% match rather than 100%. Lower percentage but often with better wagering terms than welcome offers. Regular players at a casino usually see these weekly or monthly. VIP tiers tend to have higher reload percentages.
High-Roller Bonus
Larger minimum deposit required (typically £500+) with a higher maximum bonus cap. Percentage is similar to standard welcome offers but the total bonus amount is larger. Terms are occasionally more favourable, though not always. Check the same criteria regardless of the deposit size.
How Deposit Bonuses Actually Work
Match Percentage and Cap
The percentage applies to your deposit up to the stated cap. A 200% match up to £300 on a £100 deposit gives you £200 bonus, not £300. To hit the £300 cap you need to deposit £150. Always calculate the exact bonus you will receive for your planned deposit amount rather than assuming the cap is what you get.
Wagering Requirements
The total amount you must bet before bonus-derived winnings become withdrawable. Expressed as a multiplier: 30x means 30 times the bonus amount wagered. A £100 bonus with 30x wagering requires £3,000 in total bets before you can withdraw.
Two versions exist and they are very different in practice:
- Bonus-only (30x bonus): £100 bonus = £3,000 to wager
- Deposit plus bonus (30x D+B): £100 deposit + £100 bonus = £6,000 to wager
Always check which applies. D+B wagering at the same multiplier is twice as hard to clear as bonus-only. Under 35x bonus-only or under 20x D+B is generally considered fair. Above 50x in either format is very difficult to clear without depleting the bonus before the requirement is met.
Game Contributions
Not every game counts equally toward wagering. Slots typically contribute 100%: every £1 bet counts as £1 toward the requirement. Table games including blackjack, roulette, and video poker often contribute 10% or less, and some bonuses exclude them entirely. Playing a game at 10% contribution means £10 wagered counts as £1 toward your requirement, effectively multiplying your required play by 10.
If you prefer table games and the bonus excludes them, the bonus is not well-suited to your playing style. Factor contributions into your decision before claiming, not after. Our wagering requirements guide has the full breakdown with worked examples.
Maximum Bet While Wagering
Almost every bonus imposes a maximum bet per spin or hand while bonus funds are active, typically £5. Exceeding this limit can result in the bonus and all associated winnings being voided immediately. This applies even if you were not aware of the rule. The maximum bet restriction is one of the most common reasons bonuses are forfeited. Check it in the terms before your first spin.
Time Limits
The window to meet the wagering requirement before the bonus expires. Standard range is 7 to 30 days. Under 7 days is restrictive for casual players. If the requirement is large and the time window is short, calculate whether it is realistically achievable at your typical session length before claiming.
Sticky vs Non-Sticky Bonuses
Non-sticky bonuses can be withdrawn alongside winnings once wagering is complete. Sticky bonuses are for play only and are removed when you withdraw. Most modern bonuses are non-sticky but always confirm. A sticky bonus does not change the expected value calculation meaningfully for most players, but it affects how you account for bonus funds in your balance.
Calculating Whether a Bonus Is Worth Claiming
A basic expected value check: multiply the wagering requirement total by the house edge of the game you plan to clear it on. The result is your expected loss from clearing the bonus. If that expected loss is less than the bonus amount, the bonus has positive expected value.
Example: £100 bonus, 30x bonus-only wagering (£3,000 total), clearing on a 96% RTP slot (4% house edge).
- Expected loss: £3,000 x 0.04 = £120
- Bonus received: £100
- Net expected value: £100 minus £120 = -£20
This specific bonus has negative expected value at 30x on a 4% house edge game. The same bonus on a 97% RTP slot (3% house edge): £3,000 x 0.03 = £90 expected loss, so net +£10 EV. RTP selection matters when clearing bonuses, as long as the game contributes at 100%.

Red Flags to Check Before Claiming
- Wagering above 50x on any format makes the bonus difficult to clear profitably
- Maximum bet under £2 per spin severely limits which games you can play and at what pace
- Time limit under 7 days on a high wagering requirement is almost impossible to clear for casual players
- Withdrawal cap on free spins winnings such as a £10 maximum win from 50 free spins, regardless of what you actually win
- Game list so short that only two or three specific slots qualify
- E-wallet exclusion from qualifying, especially Skrill and Neteller which are common deposit methods

Frequently Asked Questions
Can I withdraw a deposit bonus immediately?
No. The wagering requirement must be completed in full before any bonus-derived winnings become withdrawable. Attempting to withdraw before completing wagering will result in the bonus being removed along with any winnings generated from it. Only funds from your original deposit (if any remain) would be withdrawable.
What is a good wagering requirement?
Under 35x on the bonus amount alone is fair. Under 20x on deposit plus bonus is fair. The lower the multiplier, the less you need to wager before accessing winnings. No-wagering bonuses exist but are rare and typically carry lower caps or smaller amounts to compensate.
Does using an e-wallet affect my bonus eligibility?
Frequently yes. Skrill and Neteller deposits are excluded from welcome bonus eligibility at many major casinos. This is stated in the payment method section of the bonus terms, not always in the main headline. Check before depositing via e-wallet if you intend to claim a welcome offer.
What happens if I exceed the maximum bet limit?
Most casinos will void the bonus and all associated winnings. Some do this automatically, some do it during a manual review at withdrawal. Either way, exceeding the max bet is one of the fastest ways to lose a bonus. The limit applies per spin, per hand, or per round depending on the game type.
Are no-wagering bonuses actually better?
For most players, yes. No-wagering bonuses convert winnings to real cash immediately. The trade-off is they are usually smaller in headline amount. A no-wagering £20 bonus is often worth more in practice than a £100 bonus with 40x wagering, depending on your playing style and session length.
