You can form winning combinations when you match 3, 4, 5 or 6 symbols across the multiple ways to win. The extra horizontal reel is found at the top of the middle reels. With reels 2 to 5 expanding to 4 symbols per reel, if a symbol on the horizontal reel matches a symbol on the vertical reel below, it will split into 2. This means you can benefit from up to 7 symbols on the extended reels which gives you more ways to win. At most, it can reach 21,609!

Perfect Gems comes with a Win Multiplier feature – each win will see the multiplier increase by 1 with the winning symbols disappearing to be replaced by new ones. This gives you the chance to win again and again from each spin. The multiplier resets when you don’t get a winning outcome.

There’s also a Perfect Spins feature which is played when you get 3 Perfect Gem scatters – this will give you 9 free spins. If you trigger the feature with 4, 5 or 6 scatters, you will begin the feature with 15, 21 or 27 free spins respectively.

During the feature, the Perfect Gem scatter is replaced by the Spin scatter – each one you land will give you 2 more free spins with no limits to how many you can win. The Win Multiplier value you had to trigger the Perfect Spins feature is carried through to the free spins – it can only increase with each win. Again, there are no limits to how high the multiplier can go!

Perfect Gems is a nice-looking slot – the gameplay is quite simple and it has some elements from Big Time Gaming’s MegaWays game engine in there. I love the unlimited multiplier in both the base game and Perfect Spins feature which can result in payouts of 5,000 times your stake. As you can assume, it’s high variance. If you like unlimited multipliers, NextGen Gaming’s Medusa MegaWays would be my suggestion.
