Gem Blast Slot Design, Features & How It Works

Gem Blast is designed with themes like Bars, Gems, Sevens, Sky, in mind. The layout of this game is pretty standard and consists of 5 reels with 10 possible paylines. In most jurisdictions you can also select the Autoplay option when playing Gem Blast. 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 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 Gem Blast is 96% (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 €9.6. However, the RTP value is calculated over millions of spins which means the outcome of every spin will be totally random.

Game Features

Who doesn't like plenty of action and great features in a slot! Some of the most popular features available in Gem Blast is Expanding Wilds, Gamble, Respins, Sticky Wilds, Win Both Ways, It also has a bonus game, the most liked free spins bonus rounds and if you are lucky this is usually where you can win the big bucks.
