RTP is a theoretical long-run average, not a forecast for your next session. This tool cannot tell you whether a particular game is fair or whether you should play it.

Long-run math

RTP and the house edge

Per $100 wagered

96% RTP4% house edge
$96 expected return
$4 edge
94% RTP6% house edge
$94 expected return
$6 edge
90% RTP10% house edge
$90 expected return
$10 edge

These are theoretical long-run averages, not a promise about a single session. The lower the RTP, the more the same volume costs over time.

RTP is not a session forecast

Return to Player is calculated over a very large number of spins or hands. It does not say what will happen in your next session, and it does not turn a game into a safe or profitable activity.

Why the gap matters

A few percentage points can represent a meaningful difference in long-run expected cost when the amount wagered is large. Compare the published RTP with the game rules and the operator’s own disclosures. For the underlying explanation, read Why RTP Actually Matters.

What is house edge?

House edge is the theoretical percentage the operator retains over a large number of wagers. A 96% RTP corresponds to a 4% house edge.

Can a high RTP guarantee a win?

No. RTP is a long-run average. It does not guarantee a result for an individual player, session, or game sequence.
