The bonus features include Wild and Scatter symbols, Prize Multipliers, and Free Spins.

Gemmer RTP and Volatility

This gem-themed game has a low to medium variance level and an RTP of 97%.

Gemmer is a low-medium volatility slot so you can expect wins to occur frequently. However, the payouts would be on the lower side. The return-to-player percentage is a solid 97%. This parameter gives players an idea of how the game will pay out. In theory, you can receive some €97 for every €100 spent on bets.


Gemmer has a traditional feel and is focused on the precious jewels symbols. The game has a generic dark background so that the faceted gemstones could shine bright against it. As you spin the reels you will hear a pleasant soundtrack and other sound effects which are in tune with the music theme.

On the reels, you will find plenty of brightly colored jewel symbols of different shapes as well as A and K symbols also designed to look like gems. The most valuable icon is the emerald which can grant you between 50x and 2,500x of your stake.

Wild symbols can replace any other symbol except Scatter to complete a winning line. The amber gem is the game’s Scatter symbol that can trigger the Free Spins feature.
