In most jurisdictions you can also select the Autoplay option when playing Three Gems. 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 2500x your total bet, which places it slightly below the average max‑win potential found in many modern online slots. Even so, it still offers the chance for solid payouts, especially during the game’s stronger features. With a bit of luck, players can secure a meaningful boost to their bankroll, making the slot appealing to those who prefer moderate win potential without extreme volatility. This value is calculated on a very large number of spins, often a billion spins.

The standard RTP for Three Gems 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.
