RTP vs volatility in 90 seconds

Two numbers decide how a slot feels to play. RTP is how much it pays back. Volatility is how it pays.

In this guide
  1. RTP: how much
  2. Volatility: how
  3. Putting them together

Quick answer

  • RTP is the average share of stakes a slot pays back over millions of spins.
  • Volatility describes whether wins come small and often, or big and rarely.
  • Two slots with the same RTP can feel completely different to play.

RTP: how much

RTP (return to player) is a long-run average. A 96% RTP slot pays back $96 of every $100 staked, across millions of spins. It tells you the average cost of playing, not what will happen tonight.

Volatility: how

Volatility (also called variance) describes the shape of the wins.

  • Low volatility: frequent small wins. Your balance moves slowly in both directions.
  • Medium volatility: a balance of the two.
  • High volatility: long runs with little or nothing, broken by occasional big wins.

Putting them together

Slot type RTP Volatility What a session feels like
Classic fruit machine 96% low Steady, small wins
Video slot with bonus round 96% medium Quiet base game, bonus does the work
Megaways or “max win” slot 96% high Most sessions lose, a few win big

All three cost the same on average. The difference is how bumpy the ride is.
