Power Gems is a futuristic looking 5 reel, 10 payline slot from Core Gaming. It might not be the flashiest offering you’ll see but it comes with plenty of extras including re-spins with wild reels, colossal symbols or random wilds. There’s also a bonus round that continues until you land 10 winning spins. Each losing spin expands the multiplier. Play from between 20p and £500 per spin.

There’s a space age look to the design in Power Gems – the reels are made up of 5 different gemstone symbols plus the Power Gems logo. Land 3, 4 or 5 of the latter on the same spin and you’ll win an award equal to 5, 20 or 25 times your total stake. There’s also a standard wild which appears on the middle 3 reels only and pays 5 times your stake. There are 2 main extras on offer in Power Gems.

Wild Power Respin feature – these can trigger at random in the base game. A respin is awarded complete with a locked colossal wild, wild reels or random added wild. You could also trigger the main bonus offering from here – more on this below.

Winspins Bonus feature – this round is triggered by landing the Winspins Wild on reels 1 and 5 on the same spin. The free spins continue until you’ve had 10 winning spins. Each losing spin increases a multiplier by 1 until you land a winner which reverts it back to 1x. Re-triggers are possible here too, adding another 10 winning spins to your tally.

The design in Power Gems is simply done but works well enough, especially in combination with the ambient style soundtrack. The range of features isn’t massive but you can expect to land the wild modifiers in the base game regularly.

We found the free spins round much more difficult to come by. The 10 guaranteed winning spins is an intriguing proposition though, especially with the expanding multipliers hitting between the wins.

We found Power Gems to be not a million miles from the NetEnt favourite Starburst. With its simple visuals and repetitive gameplay, there’s much to like here. If you’re after some stripped back, space-themed action then Power Gems is worth closer investigation.
