'Return To Player' is the theoretical percentage of a game’s long-term payout. If a casino game had an RTP of 95%, for every pound that is wagered, the player should get 95% of that wager over the lifetime of the game. This doesn’t, however, mean that for every spin, the player is guaranteed to get a 95% of their wager back. With Live RTP, the percentage of the ‘Return to Player’ can fluctuate in real time according to how well players are doing at the current time.
