What Is a Casino Wagering Contribution Table?
A wagering contribution table is the document that tells you how much each game counts towards a playthrough requirement. It looks unglamorous, usually a small grid tucked into the bonus terms, yet it decides whether a welcome offer is genuinely generous or quietly impossible to clear. In the United Kingdom, where the Gambling Commission requires promotions to be “significant” and clearly explained, that table is one of the most important things you can read before opting in.

The concept is simple. A bonus of £100 with a 30x wagering requirement means you must stake £3,000 before withdrawing. But not every £1 you stake counts as £1. A slot may contribute 100%, a roulette table 20%, and blackjack perhaps 10% or nothing at all. The contribution table sets those percentages out, line by line.
Understanding it changes how you value a bonus entirely. A 35x requirement on a 100% slot is often easier to clear than a 20x requirement on a game that contributes 10%. The headline figure flatters; the contribution table tells the truth. This guide explains how these tables work, why the figures vary so widely, and how to read one properly before you deposit a single pound.
How Wagering Contributions Work in Practice
The table usually assigns a percentage to each game category. Slots almost always sit at 100%, because their house edge is high and predictable. Live casino games and table games tend to sit lower, typically between 10% and 50%, while some excluded games contribute 0%. That means a £10 spin on a 100% slot adds £10 to your playthrough progress, whereas a £10 hand of blackjack at 10% adds just £1.
Most UK-licensed operators apply a weighting structure similar to the following:
| Game category | Typical contribution |
|---|---|
| Slots (excluding progressive jackpots) | 100% |
| Roulette, baccarat, and card games | 10% – 20% |
| Blackjack and video poker | 0% – 10% |
| Live dealer games | 10% – 50% |
| Progressive jackpot slots | Often excluded (0%) |
There is a reason for the spread. Operators weight contributions roughly in line with each game’s house edge. Slots return less to the player per pound staked, so they count in full; a low-margin game like blackjack would let a savvy player grind through thousands in wagering with minimal expected loss. The table exists to prevent that.
Some tables go further and name individual titles. Certain high-volatility slots are excluded outright, and you will often find a capped list of games that qualify for free spins winnings. Always check whether the table applies to the bonus balance, the winnings derived from it, or both.
Why the Small Print Matters Before You Opt In
Time limits sit alongside contributions as the two most common reasons a bonus expires uncleared. A 30-day window sounds ample until you calculate the real staking volume. At 30x on a £100 bonus, you need £3,000 in qualifying stakes. At £1 per spin on a 100% slot that is 3,000 spins; drop to a 20% contribution game and the same effort clears only £600 of progress.
Look out for maximum bet rules too. Most UK operators cap qualifying stakes at £5 per spin or bet while a bonus is active, and breaching that cap can void the bonus and any associated winnings. The contribution table and the max bet clause work together, so read them as a pair rather than in isolation.
The Gambling Commission’s advertising rules require that significant conditions, including wagering requirements and game weightings, are given equal prominence to the headline offer. That is why you should expect the table to appear near the bonus description, not buried three clicks deep. If it is hard to find, treat that as a warning sign.
Reading a Contribution Table Like a Regular
Start with the headline ratio: requirement multiplied by bonus, adjusted for contribution. A £50 bonus at 40x on a 100% slot needs £2,000 staked. Check the excluded games list next, then confirm the time limit and maximum bet. Three minutes of reading saves hours of frustration.
Compare offers on effective cost rather than headline percentage. Two 100% match bonuses can carry wildly different real values once weighting is applied. A 50% contribution on live roulette, for example, can make a modest bonus far more playable for a table-game specialist than a larger slot-only offer.
Finally, remember that wagering contributions vary between operators even for identical games, and terms can change. Confirm the current table on the operator’s promotions page before depositing, and set a budget you can afford regardless of whether the bonus clears. Wagering tables reward the informed player; they punish the impatient one.
