Volatility: Low volatility usually means more frequent, smaller wins; high volatility brings fewer but larger swings. Hit Rate: Indicates how often any win occurs.
Bonus Types and What They Mean
- Welcome Match Bonus: A percentage match on your first deposit; check wagering and eligible games.
- Free Spins: Spin-specific rewards for selected Slots, often with win caps or playthrough rules.
- No-Deposit Credit: Small test credits; typically higher wagering and limited cashout.
- Cashback: A rebate on net losses over a set period, sometimes with lower wagering.
- Tournaments & Drops: Time-limited leaderboards or random prize events across featured Slots.
