In most jurisdictions you can also select the Autoplay option when playing Zero Day. You can choose from 10, 25, 50, 100 or even more spins. You can opt to stop Autoplay on a win, if a single win exceeds a certain amount, or if your balance increases or decreases by a chosen amount. This is a great way to stay in control and to play more responsibly.

Maximum Win, RTP and Volatility

The maximum win in this game is capped at 270x 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 Zero Day is 95% (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 €9.5. However, the RTP value is calculated over millions of spins which means the outcome of every spin will be totally random.

Zero Day is a high-volatility slot, with Mancala Gaming rating its volatility at Very (1/5). In slot terminology, volatility describes how frequently a game pays out and the size of those payouts. This means Zero Day 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.
