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.

Why Casinos Want You to Play Slots

In almost every single online casino, standard video slot machines contribute exactly 100% toward your wagering requirements.

Because the mathematical edge favors the house so heavily, the casino is confident they will slowly drain your balance.

• The high house edge of slots balances the casino's risk of giving away free money
• Some casinos offer bonuses that can *only* be used on specific slot titles
• Playing a 0% contributing game by mistake will waste your time and bankroll

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.

Protecting Your Bonus Funds

Within this dense legal document, there will always be a detailed table explicitly outlining the exact contribution percentage for every game.

Furthermore, if you accidentally play a restricted 0% game with active bonus funds, the casino may confiscate your entire balance.

If you want to clear a bonus quickly and efficiently, you must temporarily embrace the high volatility of the slot machines.
