When you eagerly claim a massive casino bonus, the required playthrough or wagering requirement is usually heavily advertised.
Because different games have vastly different house edges, the casino assigns a specific "contribution percentage" to each game category.
The Safest Bet for Clearing Bonuses
Casinos heavily incentivize slot play because these games operate entirely on luck and possess a significantly higher house edge.
By offering a 100% contribution rate, they actively push bonus users away from the more player-friendly table games.
- Always read the "restricted games list" before spinning with bonus funds
- Classic 3-reel slots sometimes have a lower contribution rate than modern video slots
- Progressive jackpot slots are almost universally excluded from bonus play entirely
Why Blackjack Barely Contributes
If you prefer table games like Blackjack, Baccarat, or Video Poker, clearing a bonus becomes an agonizingly slow grind.
If Blackjack contributes 10%, a $10.00 wager only removes a tiny $1.00 from your remaining playthrough total.

Protecting Your Bonus Funds
You must study this table carefully to ensure your favorite games are actually eligible for bonus play.
Furthermore, if you accidentally play a restricted 0% game with active bonus funds, the casino may confiscate your entire balance.
| Game Category | Typical Contribution % | Speed of Clearing |
|---|---|---|
| Video Slots | 100% | Very Fast |
| Blackjack | 5% - 10% | Agonizingly Slow |
If you want to clear a bonus quickly and efficiently, you must temporarily embrace the high volatility of the slot machines.
