No expense is usually spared by Yggdrasil Gaming when it comes to the design of their games and Power Plant is another fine-looking offering. That's especially the case when you opt for Golden Bet mode where the 8 rows make for impressive viewing.
Stacked wilds are the key to the action in Power Plant. Every time you land a full stack of wilds, you'll be awarded a respin. These respins come with added modifier extras. Each stack of wilds will bring 1 of the following into play. Land 2, 3 or 4 stacked wilds on the triggering spin and you can look forward to 2, 3 or 4 extras:
Swapping Symbols feature - on the respin, between 3 and 8 randomly chosen symbols will morph into the same matching symbol. The payout calculation is made with the matching symbols in play.
Nudge Reels feature - reels can shift between 2 and 4 places up or down and in the process create the optimal combination. Full stacks of wilds will remain locked in place. Partial stacks of wilds can be moved to create full stacks though which can lead to some impressive possibilities.
Super Stack feature - 1 symbol will spin in a super stacked formation during the respin.
Acting Wild feature – 1 randomly chosen symbol will become a second wild. This will spin alongside the standard wild.
Extra feature - this adds an extra modifier into the mix. For example, if you triggered with 1 modifier, the +1 would give you a second.
Power Plant offers a nice combination of classic, mechanical design and a futuristic game engine that offers plenty of extras. The volatility here isn't nuclear though - in fact, it's in medium range with top payouts of 275 times your stake on each spin/respin.
Yggdrasil Gaming has built another impressive slot game here. The variance may not be quite high enough for real action hounds but the combination of classy design and modifier extra respins make Power Plant a very interesting proposition. I also recommend you try some of their other games including Super Heroes and Vikings Go Wild.
