A Guide To Casino Bonus Contributions

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.

Slot Machines: The 100% Contribution Standard

Casinos heavily incentivize slot play because these games operate entirely on luck and possess a significantly higher house edge.


However, players must carefully check the terms, as some specific high-RTP slots (like Blood Suckers) are often explicitly excluded.

Always read the "restricted games list" before spinning with bonus fundsClassic 3-reel slots sometimes have a lower contribution rate than modern video slotsProgressive jackpot slots are almost universally excluded from bonus play entirely
The Mathematical Penalty on Skill Games

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

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.
