Maximum Win, RTP and Volatility
The maximum win in this game is capped at 12500x your total bet, giving players the chance to land really large payouts during the most rewarding features. This is considered a high maxwin potential and can result in substantial prizes when high-value symbols or strong bonus combinations align. While hitting the cap is rare, the possibility of such a payout adds extra excitement to every spin. This value is calculated on a very large number of spins, often a billion spins.
The standard RTP for Second Thunder is 94.2% (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 €9.42. However, the RTP value is calculated over millions of spins which means the outcome of every spin will be totally random.
Second Thunder is a high-volatility slot, with Thunderkick rating its volatility at (4/5). In slot terminology, volatility describes how frequently a game pays out and the size of those payouts.
This means Second Thunder 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.
