WHAT IS GAME WEIGHTING?
Game weighting, also called game contribution, is the percentage of each bet that counts toward a bonus wagering requirement, set per game category. Slots usually contribute 100%, table games 5% to 20%, and live dealer or provably fair originals frequently 0%. A $10 bet on a 10% game clears only $1 of playthrough.
How contribution percentages work
Every bonus comes with a contribution table buried in its terms. The casino multiplies each stake by the game's percentage and adds the result to your cleared turnover. Low-edge games get low percentages precisely because they are cheap to grind through: the operator wants your wagering done on games where it keeps 3% to 6% of every bet, not 0.5%. Games with an RTP above about 97%, bonus-buy features, and anything where you can bet both sides (roulette red and black, baccarat player and banker) are often excluded outright at 0%.
Reading a contribution table
Look for headings like "game contribution", "counts towards wagering", "weighting table" or "excluded games". A typical crypto casino table reads:
- Slots — 100%, minus a list of restricted high-RTP, jackpot and bonus-buy titles.
- Video poker — 10%.
- Blackjack and baccarat — 5% to 10%.
- Roulette — 10% to 20%.
- Live casino — 0% to 10%.
- In-house originals (dice, crash, plinko, mines) — 0%.
Some operators invert this for crypto-native players and allow originals at 100% but then apply the max bet rule harder. The contribution table interacts with the wagering requirement, so always read the two together.
Choosing the game that actually clears the bonus
Weighting decides which game you are really being asked to play. If originals are at 0% and you only play crash, the bonus can never be cleared, and the funds sit locked until they expire. If a 98% RTP slot is excluded, you are pushed toward 94% to 96% titles, which raises the expected cost of a $4,000 playthrough from $80 to between $160 and $240. Before accepting a bonus, find the highest-RTP game that still carries 100% weighting and check it against the max bet cap. The wagering requirement calculator lets you enter the contribution percentage directly, and the bonus EV guide walks through the full cost model.
Game Weighting FAQ
What does game contribution mean in a casino bonus?
It is the share of each bet that counts toward clearing the bonus. A 100% game credits the full stake, a 10% game credits a tenth, and a 0% game credits nothing, so the same $1,000 of play can clear $1,000, $100 or $0 of the requirement.
Do table games count towards wagering?
Usually only partially. Blackjack, baccarat and roulette are commonly weighted 5% to 20%, and some casinos exclude them entirely because low house edge and even-money bets make the requirement too cheap to grind.
Why is blackjack only 10% weighting?
Because its house edge is around 0.5% with sound play. At 100% weighting a player could clear a 40x requirement at a fraction of the cost of slots, so operators scale the contribution down until the expected cost is similar or higher.
Which games count 100% towards wagering?
Most standard video slots, excluding titles the casino lists as restricted, which is often the highest-RTP games, jackpot slots and anything with a bonus-buy option. The exact list is in the bonus terms and changes between operators.
