Maximum Win, RTP and Volatility
The maximum win in this game is capped at 61720x 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 Castle of Terror is 96.72% (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 €9.672. However, the RTP value is calculated over millions of spins which means the outcome of every spin will be totally random.
Castle of Terror is a high-volatility slot, with Big Time Gaming rating its volatility at (5/5). In slot terminology, volatility describes how frequently a game pays out and the size of those payouts.
This means Castle of Terror delivers fewer wins overall, but the payouts it can produce are significantly larger compared to low-volatility titles. It’s built for players who enjoy high-risk gameplay, sharp adrenaline spikes, and the potential for substantial rewards in exchange for longer dry spells.
