What Is a Casino Welcome Bonus?
A welcome bonus — also called a sign-up bonus or first deposit bonus — is an offer made to new players when they register and make their first deposit. The most common format is a deposit match, where the casino adds a percentage of your deposit as bonus funds. For example, a 100% match up to £200 means a £200 deposit gives you £400 total to play with.
Some welcome packages also include free spins on selected slot games. Understanding exactly what you're getting — and what's expected in return — is essential before you claim anything.
The Key Term: Wagering Requirements
Wagering requirements (also called playthrough requirements) are the most important clause in any bonus offer. They specify how many times you must bet the bonus amount (or the bonus plus deposit) before you can withdraw winnings derived from that bonus.
A Practical Example
You deposit £100 and receive a £100 bonus. The bonus carries a 30x wagering requirement on the bonus amount. That means you must wager £100 × 30 = £3,000 before your bonus funds convert to withdrawable cash.
If the requirement applies to the bonus plus deposit, the total becomes £200 × 30 = £6,000 — a meaningful difference.
What Counts as a Good Wagering Requirement?
| Wagering Multiplier | Assessment |
|---|---|
| 10x–20x | Excellent — very achievable |
| 21x–35x | Fair — reasonable for most players |
| 36x–50x | High — requires significant play |
| 50x+ | Very high — bonus may not be worth claiming |
Game Contribution Rates
Not all games contribute equally to clearing your wagering requirement. Casinos typically weight games like this:
- Slots — usually 100% contribution
- Blackjack — often 10%–20% (sometimes excluded entirely)
- Roulette — commonly 10%–20%
- Live casino games — frequently 0%–10%
- Video poker — varies widely, often low
This matters a great deal. If you prefer table games, a bonus that only clears via slots may effectively be worthless to you.
Other Bonus Terms to Watch
Expiry Date
Most bonuses expire within 7–30 days. If you haven't met the wagering requirement in that window, the bonus and any associated winnings are forfeited.
Maximum Bet Restrictions
When playing with active bonus funds, casinos typically cap individual bets at £5–£10. Exceeding this limit — even once — can result in your bonus and winnings being voided. Read this rule carefully.
Maximum Withdrawal Cap
Some bonuses cap the amount you can withdraw from bonus winnings, regardless of how much you've won. A cap of £50–£100 on a £200 bonus can be frustrating if you hit a big win.
Eligible Games
Certain slots — particularly jackpot games — may be excluded from bonus play even if slots generally contribute 100%.
Types of Casino Bonuses Beyond the Welcome Offer
- Reload bonuses — offered on subsequent deposits, usually smaller percentages
- Free spins — no-cash spins on specific slots; wins often carry wagering requirements
- No-deposit bonuses — small bonus or free spins given without a deposit; usually have high wagering requirements
- Cashback offers — a percentage of net losses returned, sometimes without wagering requirements
- Loyalty programmes — points accumulated over time that convert to bonus funds or perks
Should You Always Claim a Bonus?
Not necessarily. If you prefer table games or live casino, bonuses with slot-heavy contribution rules may actively work against you by locking your deposit until wagering is complete. In some cases, playing without a bonus gives you more flexibility. Always weigh the terms against your actual playing habits before opting in.
Final Thoughts
Welcome bonuses can add genuine value — particularly low-wagering deposit matches and cashback offers — but only when you understand the full set of conditions attached. Read the T&Cs, calculate the total wagering required, and check which games contribute before claiming any offer.
