CASINO GLOSSARY
Twelve terms that decide whether a crypto casino is worth your deposit — defined in plain English, with the real numbers behind them. Every definition is consistent with the data in our casino rankings and reviews.
RTP (RETURN TO PLAYER)
The percentage of all wagers a game returns to players long-run — a 96% RTP slot pays back $96 per $100 wagered.
Read definition →HOUSE EDGE
The casino's built-in margin on every bet: 100% minus RTP. Stake's crash runs 1%; blackjack as low as 0.5%.
Read definition →WAGERING REQUIREMENT
The multiplier of bonus value you must bet before withdrawing — 40x on a $100 bonus means $4,000 in wagers.
Read definition →RAKEBACK
A rebate of the house edge paid on every bet, win or lose, with no wagering requirement attached.
Read definition →SERVER SEED
The casino's secret random string in provably fair games, committed by SHA-256 hash before you bet.
Read definition →NONCE
The counter that rises by one each bet so every result under the same seed pair is unique and verifiable.
Read definition →PROVABLY FAIR
The cryptographic system that lets you recalculate any game result yourself and prove it was never manipulated.
Read definition →MAX BET RULE
The bonus term capping single bets (usually $5) while wagering — exceed it and winnings can be voided.
Read definition →STICKY BONUS
Bonus money you can play with but never withdraw; only winnings above it are cashable.
Read definition →SLOT VOLATILITY
How a slot delivers its RTP: frequent small wins (low) or rare big hits (high) at the same long-run return.
Read definition →KYC
Identity verification with photo ID and proof of address — at crypto casinos usually triggered by withdrawals.
Read definition →CASHOUT
Withdrawing winnings to your own wallet — or the crash-game button that locks in your current multiplier.
