What Are Game Contribution Percentages?
Game contribution percentages determine how much of your bets count toward meeting bonus wagering requirements. Not all games contribute equally - some count 100% while others may contribute only 10% or even 0%. Understanding these percentages is crucial for efficiently meeting wagering requirements and avoiding games that don't help you progress. In 2025, contribution percentages remain one of the most misunderstood aspects of casino bonuses.
💡 Key Insight
Playing a game with 10% contribution means you need to wager 10 times more than if you played a 100% contribution game. Always check contribution percentages before playing.
How Contribution Percentages Work
Basic Calculation
Contribution percentages determine how much of your bet counts toward wagering:
| Contribution % | Bet Amount | Counts Toward Wagering | Effective Multiplier |
|---|---|---|---|
| 100% | $10 | $10 | 1x (standard) |
| 50% | $10 | $5 | 2x (need to bet twice as much) |
| 20% | $10 | $2 | 5x (need to bet 5 times as much) |
| 10% | $10 | $1 | 10x (need to bet 10 times as much) |
| 0% | $10 | $0 | ∞ (doesn't count at all) |

Why Contribution Percentages Vary
House Edge Considerations
Games with lower house edges often have lower contribution:
- Blackjack: Low house edge (0.5-1%) = Low contribution (10-20%)
- Slots: Higher house edge (3-5%) = High contribution (100%)
- Reason: Casinos protect their profit margins
Game Strategy Impact
Games where skill can reduce house edge get lower contribution:
- Blackjack: Basic strategy reduces edge
- Video Poker: Optimal play reduces edge
- Result: Lower contribution to protect casino
Calculating Effective Wagering with Contribution
The Formula
To calculate how much you need to bet with different contributions:
Effective Wagering = Required Wagering ÷ Contribution %

| Slots | 100% | $6,000 ÷ 100% | $6,000 |
| Video Poker | 50% | $6,000 ÷ 50% | $12,000 |
| Blackjack | 20% | $6,000 ÷ 20% | $30,000 |
| Roulette | 10% | $6,000 ÷ 10% | $60,000 |
