Crystal Mine tells yet another story of dwarf miners who tirelessly search for gems day and night in deep dark mines. Everyone knows about the passionate love of these hardworking creatures for wealth. Mancala Gaming could not ignore such an interesting theme, since all slot machine players do about the same in search of their benefit. The slot is filled with the following features: 3 special symbols, Bonus Game and Free Spins.

RTP & Volatility

Surely finding precious metals in the mine of this lot is not easy, since the theoretical return to the player is 95%, which is much lower than the market average and the volatility tends to be high. But if you gather your strength into a fist, you can win up to 10,500x the stake!

Free Spins Feature

After any spin that fails to bring a winning combo, you move one space on the free spins progress counter. Once you reach the 3rd space you will get a free spin. Reaching the 4th space gives 3 free spins. If you get a winning combo the slot will reset the number of free spins that you have collected. Fill the counter to the end and you can get up to 250 free spins!
