The Gem Machine Review

This online video slot might be made from all classic gem symbols, but it is an innovation from the first spin to the last. Provider Scientific gaming has built Gem Machine so that you can select the number of reels to spin, from one to five. At first, all the positions of the grid are gray. As they spin, colourful gems set on it or even Free Spins symbols.

A win line is considered any combination during which you land at leas one colourful gem. To spin the reels and succeed with that, you must first place a starting bet of at least €0.05 bet per reel.

Be on the lookout for gem multipliers. Each coloured gem comes with its own:

  • Yellow Gem offers up to x1000
  • Blue Gem can award as much as 50x
  • Green Gem can grant up to 5x

Triggering the Free Spins bonus round is achieved by landing a Free Spins symbol. One symbol can award anywhere between 1 and 5 freebies. And, since there are 15 positions on the grid, you could theoretically land 75 Free Spins in one spin.

Landing any of the Jackpot symbols instantly grants you the corresponding Jackpot. The total amount of a jackpot is dependent on the bet per spin.

The Gem Machine Slot Game Features

Bonus Rounds: Grand Jackpot, Major Jackpot, Mega Jackpot, Minor Jackpot, Mini Jackpot, Free Spins

Symbols: Green Jem, Blue Jem, Yellow Jem, Free Spins, White Grand Gem, Purple Grand Gem, Red Grand Gem, Turquoise Grand Gem, Green Gem,

Free Spins: Yes

Why play it: The Gem Machine is an unique slot, where you can select the number of reels you want active per spin. Another one of a kind feature is the absence of paylines and the fact that a win is whenever you land a gem on the reels.
