When you eagerly claim a massive casino bonus, the required playthrough or wagering requirement is usually heavily advertised.
Casinos do not treat all of their games equally when it comes to clearing these massive bonus requirements.
The Safest Bet for Clearing Bonuses
This means that if you wager $1.00 on a spin, exactly $1.00 is subtracted from your remaining playthrough total.

Because the mathematical edge favors the house so heavily, the casino is confident they will slowly drain your balance.
- Video slots are the absolute fastest way to clear any standard casino bonus
- A $5 bet on a 100% contributing game removes $5 from the requirement
- Casinos prefer slot players because the games rely entirely on pure chance
Why Blackjack Barely Contributes
Because these games feature an incredibly low house edge (often under 1%), casinos heavily penalize them regarding bonus contributions.
If Blackjack contributes 10%, a $10.00 wager only removes a tiny $1.00 from your remaining playthrough total.
Where to Find the Contribution Table
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.
| Wager Amount | Contribution Rate | Amount Deducted from Goal |
|---|---|---|
| $20 on Slots | 100% | $20.00 |
| $20 on Baccarat | 10% | $2.00 |
Wagering contributions are the casino’s mathematical safety net, carefully designed to protect them from skilled table game players.
