Casino Wagering Requirements Explained
Wagering requirements are the single most important thing to understand before claiming any casino bonus. A £100 bonus with 40x wagering isn't worth £100 — it requires £4,000 in bets before you can withdraw. Understanding the maths helps you decide which bonuses are worth taking and which to skip.

What Are Wagering Requirements?
Wagering requirements (also called playthrough requirements) specify how many times you must bet a bonus amount before you can withdraw winnings from it.
Example: You receive a £100 bonus with 40x wagering.
40 × £100 = £4,000 you must wager before withdrawing.
Some casinos apply the requirement to bonus + deposit combined:
40 × (£100 deposit + £100 bonus) = £8,000 required.
Always check whether the multiplier applies to the bonus only or to the bonus + deposit amount.
How to Calculate Real Bonus Value
The real value of a bonus accounts for the house edge you'll lose during wagering:
| Wagering Requirement | Total to Wager | Expected Loss (at 4% edge) | Real Bonus Value |
|---|---|---|---|
| 10x | £1,000 | £40 | £60 |
| 20x | £2,000 | £80 | £20 |
| 30x | £3,000 | £120 | -£20 (negative value) |
| 40x | £4,000 | £160 | -£60 (negative value) |
| 50x | £5,000 | £200 | -£100 (effectively worthless) |
Which Games Count Towards Wagering?
Most casinos restrict which games count towards clearing wagering requirements:
Typically 100% contribution: Video slots
Typically 10–20% contribution: Blackjack, roulette, baccarat, video poker
Typically 0% contribution: Live dealer games (some casinos), certain table games
This is important: if you want to complete wagering with table games, you may need to wager 5–10 times more than the stated requirement. Always read the game contribution table in the bonus terms.

Common Bonus Traps to Avoid
Maximum bet restrictions: Most bonuses limit bets to £5–£10 while wagering. Exceeding this can void the bonus. Always check the max bet rule.
Game restrictions: Some games are excluded entirely during bonus play. Playing excluded games can void your bonus.
Expiry time: Bonuses typically expire in 7–30 days. If you can't realistically complete wagering in time, don't claim the bonus.
Maximum withdrawal cap: Many bonuses cap withdrawals at a multiple of the bonus amount (e.g., 3x bonus). A £100 bonus with 3x max cashout means maximum withdrawal of £300 regardless of how much you've won.
What Makes a Bonus Worth Taking?
Based on the mathematics, bonuses worth taking have:
✓ 30x wagering or less (on bonus only, not deposit + bonus)
✓ Slots contributing 100% to wagering
✓ No maximum bet restriction below £5
✓ Expiry of 14+ days
✓ No maximum cashout cap (or a generous cap)
✓ Reasonable maximum withdrawal (5x bonus or higher)
No-deposit bonuses and free spins often have more restrictive terms (higher wagering, lower max withdrawal) but require no real-money deposit — they can provide value even with tighter terms.
Frequently Asked Questions
What is a good wagering requirement for a casino bonus?
30x or lower on the bonus amount only is considered favourable. 40x and above is high. Some casinos offer 10–20x requirements on select promotions — these represent genuine value.
Can I withdraw my deposit while bonus wagering is active?
Typically no — most casinos lock your deposit until bonus wagering is complete or the bonus is forfeited. Check the specific terms before claiming.
Should I always claim casino bonuses?
Not always. High-wagering bonuses (40x+) often have negative expected value. Sometimes playing without a bonus (and therefore without restrictions) gives you more flexibility and equal or better expected returns.
What does 'bonus + deposit' wagering mean?
The wagering multiplier applies to the combined deposit and bonus amount, not just the bonus. A 30x requirement on £100 deposit + £100 bonus = £6,000 to wager — double what '30x bonus only' would require.
Do free spins have wagering requirements?
Almost always — winnings from free spins are typically subject to 20–40x wagering before withdrawal. The real value of free spins is small, but since they require no deposit, even low-value spins are usually worth claiming.
