What the RTP actually means

RTP is a long-run theoretical average across millions of spins — not a promise for your session. At 96.55%, the built-in house edge is 3.45%. Use the estimator to see the expected theoretical cost of play — variance means real results swing far around it.

Total wagered
Expected theoretical loss

Expected loss = wagered × (1 − RTP/100). A model, not a prediction — you can lose far more or win on any given session. Set a budget with 55LL.
