Maximum Win, RTP and Volatility

The maximum win in this game is capped at 500x your total bet, which is considered very low compared to many modern online slots. However, a lower maxwin cap often goes hand-in-hand with more frequent smaller payouts, giving players a steadier and more predictable gameplay experience. This makes the slot suitable for those who prefer consistent wins over high-risk, high-reward volatility. This value is calculated on a very large number of spins, often a billion spins.

The standard RTP for King Colossus is 96.6% (Can be lower on some sites). This is good and above 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 €9.66. However, the RTP value is calculated over millions of spins which means the outcome of every spin will be totally random.
