The main action in the game is focused on the Gemmed! bonus round. This is a hold & respin style feature that triggers whenever players land six gems of any kind on the grid. Gem symbols always display a multiplier. Blue diamond gems are the highest paying, with a maximum prize of up to 2,000x, followed by the pink, magic, red, and diamond, which can have a maximum of 250x, 100x, 50x, and 10x, respectively.
Players are given three respins, with the triggering symbols locked in position. Any new gems that land during these spins will also lock, and the respin count resets. When the spins have run out, the total of the diamonds is added together and paid out.
The only other feature in the game is the Gem Sack symbol. If this lands on the top horizontal reel, then three gem symbols are added to random positions on the reel. This can be a great way of getting a boost to trigger the Gemmed! bonus.
