Power Gems

Developed by Core Gaming and released on the Open Bet platform, Power Gems fits right in with those Starburst-looking, futuristic slots which are all the rage right now. Just like its counterparts, it heavily features gemstone symbols and is not afraid to offer players a limited gaming structure. This makes it ideal for players operating on a budget, costing just 20p per spin. However, those players with a larger wad to spend can splash the cash up to £500 a spin on this slot. Don’t be surprised to find a smaller non-progressive jackpot than you may be looking for, with the one in this game capped at 25x your total bet. It is won when players land 5 of the game’s title logo on a payline.

Special features

There are several types of wild symbols which can appear in this game. First and foremost, there is a wild symbol which can appear on the second, third and fourth reels. This wild can substitute for any other standard paying icons, and dish out wins worth up to 5x your total bet.

At any point in the base game, players may randomly trigger a re-spin. When this occurs, other types of wild appear (colossal wilds, wild reels or random wilds) which can help bolster your wins on that re-spin.

Players should also keep an eye out for the Winspins Wild. This wild can substitute for other icons, but it can also trigger the main bonus feature in the slot if it lands on the first and fifth reels at the same time.

Bonus features

The Winspins Bonus (triggered via those Winspins Wild symbols) offers players a total of 10 winning spins. This means that, in theory, you’ll have unlimited spins until you win at least 10 times. Every losing spin you encounter increases a multiplier by 1x, and when you’ve won it drops back to its base minimum of 1x. You can retrigger the bonus, too.


For such a simple slot, there’s a lot going on in Core Gaming’s Power Gems. This makes it far more prosperous than even NetEnt’s Starburst slot, which until now has set the benchmark for these kinds of games, but no more.
