Why Not All Wagers Count Equally
Every deposit bonus comes with wagering requirements attached, but the headline figure rarely tells the full story. Game weighting is the mechanism that decides how much of each stake counts towards clearing those requirements, and it can stretch or shrink the real cost of a bonus dramatically.

Put simply, a wager on a slot might contribute 100% towards the requirement, while the same amount staked on roulette could count for just 10% or 20%. On a £100 bonus with 35x wagering, you would need £3,500 in qualifying stakes. If every bet only counted at 10%, you would actually have to stake £35,000 to clear it.
This is why reading the weighting table before opting in matters far more than the size of the bonus itself. A generous-looking offer with harsh weighting can cost far more than a modest bonus with favourable terms.
The Typical Weighting Bands
Most UK-licensed operators publish a contribution table in their terms. The pattern is fairly consistent, though the exact percentages vary between brands.
| Game Category | Typical Contribution |
|---|---|
| Slots (most titles) | 100% |
| Scratchcards and bingo | 100% |
| Roulette and blackjack | 10%-20% |
| Video poker and live dealer games | 0%-10% |
| Excluded titles | 0% |
Slots dominate because their house edge and volatility suit high-volume wagering. Tables and live games are weighted down heavily, sometimes excluded entirely, because their low house edge makes them a cheap route to clearing bonuses.
A few operators apply reduced weighting even to selected slot titles, often progressive jackpot games or high-RTP releases. Checking the small print for named exclusions takes a minute and can save hours of staking.
Working Out What a Bonus Really Costs
The practical calculation is straightforward. Divide the total wagering requirement by the contribution percentage of the game you intend to play. A £50 bonus at 30x requires £1,500 in qualifying stakes; played on a 100% weighted slot, that is £1,500 of real turnover. Played on a game weighted at 20%, it becomes £7,500.
Free spins packages deserve the same scrutiny. Winnings from spins are usually credited as bonus cash with their own wagering terms, and the weighting rules apply again. A 50-spin offer that looks costless at the door can carry a four-figure clearing target once the maths is done.
Where a site prices its offers honestly, the numbers are laid out plainly. Platforms that publish clear, per-game contribution figures, such as those listing £30 no deposit terms and 100 free spins with transparent weighting, let you compare offers on like-for-like staking totals rather than headline values.
Weighting is not a hidden trap so much as a pricing signal. The clearer the table, the fairer the offer tends to be.
