How Casino Welcome Bonuses Work — Wagering Requirements Explained

What Is a Welcome Bonus?

A welcome bonus (also called a sign-up bonus or first deposit bonus) is a promotional offer given to new players when they make their first deposit at an online casino. The most common type is a match bonus — the casino matches your deposit by a percentage up to a maximum amount.

Example: A "100% up to £200" bonus means if you deposit £200, you receive £200 in bonus funds, giving you £400 total to play with.

Understanding Wagering Requirements

Wagering requirements (also called playthrough requirements) are the most important — and most misunderstood — part of any bonus. They specify how many times you must bet the bonus (or bonus + deposit) before you can withdraw winnings.

Example calculation:
Bonus: £100 | Wagering: 35x bonus
You must bet: £100 × 35 = £3,500 before withdrawing.

What counts as a "good" wagering requirement?

• Under 20x — Excellent (rare)
• 20–30x — Good
• 30–40x — Average
• 40–60x — High — the bonus value is very limited
• Over 60x — Not worth claiming for most players

Deposit + Bonus vs. Bonus Only Wagering

Some casinos require you to wager the deposit + bonus combined, which is significantly harder. A 20x (deposit + bonus) requirement on a £100 deposit with a £100 bonus means wagering £100 + £100 × 20 = £4,000 — the same as a 40x bonus-only requirement.

Always check whether the wagering applies to the bonus only or to the deposit + bonus total.

Game Contribution Percentages

Not all games contribute equally toward wagering requirements. Typical weightings:

• Slots — 100% (most slots)
• Live casino — 10–20% or excluded
• Blackjack/Roulette — 5–20% or excluded
• Video Poker — often excluded
• Jackpot Slots — sometimes excluded

If you prefer table games, a bonus that excludes them is essentially worthless. Always read the "excluded games" list.

Time Limits

Most bonuses expire after 7–30 days. You must complete the wagering requirement within that window or the bonus (and any winnings from it) is forfeited. A 30x wagering requirement on a tight timeline can be very challenging for casual players.

Maximum Win Limits

Many casinos cap how much you can win from a bonus — often 5–10x the bonus amount. A £100 bonus with a 5x max win means regardless of how well you play, you cannot withdraw more than £500 in bonus winnings.

No-Deposit Bonuses

No-deposit bonuses give you free cash or spins without requiring a deposit. They typically come with even higher wagering requirements (40–60x), strict game restrictions, and very low max win caps (often £50–100). They are useful for trying a casino with zero risk, but converting them to real cash is difficult.

Free Spins Bonuses

Free spins are awarded on specific slots. Each spin has a set value (usually £0.10–£0.20). Winnings from free spins are credited as bonus funds subject to wagering. Key facts:

• Wagering on free spins winnings is typically 20–40x
• Often restricted to the promotional slot
• May expire within 24–72 hours if not used
