Visually, Gem Machine is a little odd – it looks like a land-based slot so graphically isn’t the sharpest you’ll find. Set within a gem machine, you can choose to play with 1, 2, 3, 4 or 5 reels active – each reel costs you 5 coins so enabling all 5 will set you back 25 coins (or 25p at minimum stakes). On the reels you’ll see blanks and 3 gems – each gem appearing will give you a cash prize:

  • Green gems give you 1, 2 or 5 times your stake
  • Blue gems give you 10, 20 or 50 times your stake
  • Amber gems give you 100, 500 or 1,000 times your stake

If you like multiple gems on the reels, all their cash totals are combined – in theory, you could see 15 amber gems which would give you a whopping 15,000 times your stake.

You’ll also see Free Spins symbols appearing – they will have a value of 1, 3 or 5. When you get 1 or more, you’ll trigger the Free Spins Bonus feature with the total of the Free Spins symbols. You can also see them during the feature to win more free spins.

On the reels you’ll also hopefully see 5 Jackpot symbols – you have the Mini, Minor, Major, Mega and Grand Jackpots which are worth 20, 40, 200, 400 or 1,000 times your stake respectively.

Above the reels you’ll see Mini, Minor, Major, Mega or Grand Jackpot prizes. These are triggered by landing the associated gemstone on the reels below. These offer instant prizes of some 20, 40, 200, 400 or even 1,000 times your total stake.

Gem Machine is rather odd but I quite like it – it’s all about the Grand Jackpot and Amber gem symbols which can give you huge prizes. The key to winning big is to get as many gems on the reels as possible. I found it a medium variance title with the bigger payouts in the Free Spins Bonus feature. If you want something more conventional, Bally’s Monopoly Millionaire and Michael Jackson King of Pop are worth playing.
