RTP, or return to player, is the percentage of total stakes a game returns to players over a very large number of rounds.
RTP is the published figure that lets you compare the long-run cost of two games. The remainder is the house edge.
A 96 percent RTP game returns 96 euro per 100 euro staked across millions of spins. The house edge is the remaining 4 percent.
No. RTP is measured across millions of rounds and all players. A single session can return anything from zero to many times the amount staked.
Some games ship with more than one RTP setting and the operator selects one at deployment. The setting in use is shown in the game information panel.
