This value is calculated on a very large number of spins, often a billion spins.

The standard RTP for 777 Rainbow Respins is 96.1% (Can be lower on some sites). This is quite low and considered to be below average for an online slot. RTP stands for Return to Player and is the percentage of stakes the game returns to the players. For example, if a player bets €10 the expected return for this game would then be €9.61. However, the RTP value is calculated over millions of spins which means the outcome of every spin will be totally random.
