Maximum Win, RTP and Volatility

The maximum win in this game is capped at 50000x your total bet, giving players the chance to land exceptionally large payouts during the most powerful bonus features. This max win value is based on long-term simulated gameplay—often billions of spins—and represents the highest possible outcome the game can produce under ideal conditions. While hitting the cap is extremely rare, the potential for big wins adds excitement to every spin. This value is calculated on a very large number of spins, often a billion spins.

The standard RTP for Sinful 7s is 95.36% (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 €9.536. However, the RTP value is calculated over millions of spins which means the outcome of every spin will be totally random.
