RTP stands for Return to Player—it is the percentage of all wagered funds that a slot game statistically returns to players over a very long cycle (often millions of spins). For example, an means the game theoretically returns our welcome offer for every our welcome offer wagered across an infinite sample. Our slot games (Aviator, Sweet Bonanza, Gates of Olympus, Fortune Tiger, Mahjong Ways) display their RTP in the game information menu.
