Game Contribution & Wagering Requirements
Why a 10%, 25% or 50% game-contribution rule can multiply the actual betting needed to clear a casino bonus.
Contribution determines how much of each dollar wagered counts toward the promotion requirement. Actual action required equals credited wagering divided by the contribution rate.
100% contribution
Every $1 wagered creates $1 of credited turnover.
25% contribution
Every $1 wagered creates $0.25 of credited turnover, so four dollars of actual action are required for each credited dollar.
10% contribution
Ten dollars of actual action are needed for each credited dollar.
Why low-edge games are often restricted
A promotion may reduce or exclude contribution from games with lower house edges, which changes the cost of using those games to clear the promotion.
Always use the actual terms
Contribution tables are promotion-specific and can change. Do not assume a game contributes merely because it is available on the site.
