Gem Rush

Do you remember the peak of the California Gold Rush from 1848 to 1855? So, these events are now taking place in the Gem Rush machine by Slotmill. Avalanche mechanics and a mini-drum, in which you can get additional dynamite or a portion of multipliers, will help you get gold.

In the gold mine, you can forge many valuable artifacts that can be exchanged for real funds. For example, card suits are paying up to 0.60x, miners' inventory is up to 0.60x, and crystals are up to 2x. Bonus symbols will open the game with spins, while Wild symbols substitute for any payout values. Please note that there are 15 empty cells in the grid that can be removed if you catch a winning combo. Also, on the right, you will receive a mini-drum, in which you can get additional achievements.

Well-well-well, the game about gems…No chances for me to pass it! Especially given the slot’s gameplay that includes 7 random features in the base game and free spins with a fully open board.
Honestly, I was very excited once I saw the game in the lobby and checked its rules. Being excited is ok, but not overexcited. The reality can be pretty cruel, as the slot is very volatile and all those features won’t necessarily give you massive wins. My advice – take the game seriously!
