A wagering requirement (also called a rollover or playthrough requirement) is the number of times you must bet through a bonus before you can withdraw the resulting funds as cash. It is the most important number to check on any bonus offer. Here is a plain-English explanation with real calculations.
How Wagering Requirements Work
When you receive a bonus with a wagering requirement attached, the bonus funds (or the bonus winnings, depending on the offer type) must be bet a specified number of times before they become “real” withdrawable cash. The requirement is expressed as a multiplier: 5x, 20x, 40x, etc.
Formula: Total wagering required = Bonus amount × Wagering multiplier
- €50 bonus × 5x = €250 total bets required
- €50 bonus × 20x = €1,000 total bets required
- €50 bonus × 40x = €2,000 total bets required
The Real Cost of Higher Wagering Requirements
Every time you place a bet, the operator has an edge (the margin). On football, this is typically 4–6%. On slots, it can be 3–10% or more. The higher the wagering requirement and the higher the margin, the more of your bonus you are expected to lose clearing it.
| Bonus | Wagering | Total bets needed | Expected loss at 5% margin | Net value |
|---|---|---|---|---|
| €50 free bet (SNR) | 5x | €250 | €12.50 | ~€12–€15 |
| €50 casino bonus | 20x | €1,000 | €50+ (at slot margins) | Near zero |
| €50 casino bonus | 40x | €2,000 | €100+ (at slot margins) | Negative expected value |
Sports free bets at 5–10x are genuinely valuable for Irish punters. Casino bonuses at 35–40x with slot wagering have near-zero expected value.
Qualified Contributions: Not All Bets Count Equally
Many bonuses specify that bets on certain markets contribute less than 100% to wagering. For example, football accumulator bets might count 100% but each-way horse racing bets might count 50%. Casino slot play might count 100% but live casino bets count 10%. Check the contributions table in the bonus T&Cs.
GRAI Requirements for Transparency
Under GRAI inducements regulations, wagering requirements must be displayed clearly alongside any bonus headline figure. “Hidden” wagering requirements buried in terms pages are a potential compliance breach you can report to the GRAI at grai.ie.

Wagering Requirement vs No-Wagering: Comparison
| Bonus Type | Wagering | Real Value on 100 euro Bonus |
|---|---|---|
| Standard 35x bonus | 35x = 3500 euro to wager | Approximately 40-60 euro expected value with 2% slots loss |
| No-wagering cashback 20% | None | 20 euro real cash on 100 euro losses |
| 10x low-wager match | 10x = 1000 euro to wager | Approximately 80 euro expected value |
| SNR free bet | No wager - stake not returned | Odds minus 1 divided by odds times bet |
Simple formula: Bonus Value = Bonus Amount minus (Wagering Requirement times House Edge). For a 100 euro bonus at 35x wagering, with a 3% average house edge: 100 minus (3500 times 0.03) = minus 5 euro. This means you are statistically expected to lose more than the bonus gives you. Bonuses become positive-value when: wagering is 20x or under, house edge is 2% or under, or no wagering. 18+.
The number of times you must bet through the bonus amount before winnings are withdrawable. A 5x wagering on a €50 bonus means placing €250 in total bets that qualify before the bonus converts to cash.
5x is considered low and very achievable. The expected cost of clearing it at typical sports margins is €12–€15 on a €50 bonus. Bonuses above 20x for sports are poor value.
Casino bonuses with 35–40x wagering played primarily on slots. At typical slot margins, the expected losses to clear the wagering exceed the bonus value — these bonuses have negative expected value.
Not always. Many bonuses have contribution rates: sports bets typically 100%, live casino bets often 10–20%, some markets excluded. Check the contributions table in the bonus T&Cs.
Yes — bonus wagering requirements are legal. GRAI rules require them to be clearly disclosed. The GRAI does not cap wagering requirements but enforces transparency obligations.
