Gather Up Your Power Gems
Power Gems is a colourful online slot from CORE gaming best suited for mobile play due to its theme and casual play style. CORE has been more quiet than usual recently but they are known for titles like Reels of Fire, Cryptex 7, Rosella: Lucky Fortunes and the classic fruit machine style Bar Star.
Power Gems may not have the most exciting or engaging slot theme but the explosive animations and simple reel symbols do have an appeal to them. The 95.02% RTP on offer here is a bit low but the main jackpot is decent at 250 000. Wagers thankfully start quite low, with the minimum wager possible being 0.20.
A Simple Design
The reels are setup in a 5×3 grid and there are 10 paylines to activate. Technically there are 20 paylines as you get a both-ways-pay feature on your paylines meaning you can form winning combinations left to right and right to left.
The reel symbols in Power Gems are pretty bland. They are shiny and sparkly enough but there isn’t much personality between symbols, other than a colour and shape change. The highest value gems that you’ll see on the reels are the Power Gems game logo.
To keep your wins coming in thick and fast, also look out for the purple wild symbol. This symbol substitutes for any of your other gems. There is also a small bonus amount on offer if you can land 3 of the wilds on an active payline.
A Guaranteed Win Spin
The main way to make some cash in Power Gems slot is with the Winspin bonus feature. To trigger this reel 1 and 5 should each feature a Winspin symbol when your spins end. You get 10 free spins but there is an additional feature that makes this feature much better than a standard free games round.
Each non winning spin you make will increase your win multiplier by 1. This modifier will drop back to 1x after you land a winning spin. If another two Winspin icons land on the corner reels you can retrigger this feature and get another full 10 free spins.
Players can also look forward to the randomly triggering Wild Reel Modifiers. These come in 4 varieties, Wild Reels, Colossal Wilds, Random Wilds and Bonus triggering wilds. These special wilds only show up during the base game.
