Not all slots are equal. Two metrics tell you what to expect before you stake a single coin.

RTP (Return to Player)

The long-run percentage paid back to players. A slot with 96% RTP returns $96 for every $100 wagered over millions of spins — the casino keeps 4%. Look for 96%+; avoid anything below 94%.

Volatility (Variance)

  • Low — frequent small wins, good for stretching a small bankroll
  • Medium — balanced mix
  • High — rare but large wins, high bust risk
  • Very high (Buy Feature slots) — Gates of Olympus, Dead or Alive 2 — can pay 5,000x+ but dry spells are brutal

Which to Pick

Small bankroll or just want entertainment? → Low or medium volatility slots like Book of Dead or Starburst. Chasing a big win and willing to risk busting fast? → High volatility like Gates of Olympus or Mental.

Where to Find RTP

Check the game's info/paytable screen. Reputable providers like Nolimit City and BGaming publish RTP openly.
