Understanding RTP (Return to Player) and volatility helps you choose games that match how you like to play — and how well they count toward wagering requirements.
RTP: Return to Player
RTP is the percentage of all bets a game pays back to players over time. It's a long-term theoretical average, not a guarantee for each session.
- 96% RTP — For every $100 wagered, the game is designed to return $96 to players over millions of spins. The casino keeps about $4.
- 97% RTP — Slightly better odds; $97 returned per $100 wagered.
- Online slots typically range from 94% to 99%+. Licensed games display RTP in the paytable or info section.
Volatility (Variance)
Volatility describes how often and how big wins tend to be. It does not change RTP — a high-volatility slot still has the same long-term return; wins just come less often and can be larger.
| Type | Wins | Bankroll impact | Typical games |
|---|
| Low volatility | Frequent, smaller wins | Balance fluctuates less | Classic slots, some jackpot games |
| Medium volatility | Mix of small and occasional big wins | Moderate swings | Many video slots |
| High volatility | Rare but potentially large wins | Long dry spells; big hits possible | Megaways, high-variance slots |
Why This Matters for Bonuses
When completing wagering, low-volatility slots can stretch your bonus longer (more spins, smaller swings). High-volatility slots may drain your balance faster or deliver big wins — both affect how easily you reach the playthrough target. Slots almost always contribute 100% to wagering; check each game if unsure.
