If you have ever been wondering how the interior of a power plant looks, now you have a chance of visiting the core of one with the brand new video slot of the same title launched by Yggdrasil Gaming. Get ready to embark on a journey to an electrified industrial world with the futuristic game Power Plant featuring an innovative layout with staggering 82 paylines and the maximum 32,800 coin payout you can win in a single spin.

The game features a 5×8 grid which resembles the concept of Colossal Reels. In contrast to such games where Colossal Reels are an addition to the main set of the reels, the Power Plant slot is played at the grid consisting of 5 reels and 8 rows which provides players with multiple opportunities to win. The game looks great, especially on mobile devices as it is played in portrait mode.

Stacked Wilds

The minimalistic soundtrack and the interior lit by neon lights along with bonus features contribute to the dynamic gameplay. Throughout the game you will benefit from stacked symbols including Wilds which have also the superpower of triggering respins with random bonus features which can boost your winning chances substantially.

Game Symbols

All the symbols appearing on the reels are theme-related and we can admit that they are rendered very carefully. They are represented as a set of symbols associated with electricity generation such as the ionising radiation, fire and voltage symbols. We appreciate that such an innovative game is not impaired by the use of playing card symbols and other generic stuff.

The only special symbol in the game is Wild which can be easily recognised by the W letter on it. It appears on all the reels in stacks.


The innovation in this Yggdrasil Gaming release is not limited only to its appearance but the way the game is played also differs from the rest of the Malta-based developer’s production. In their effort to make the game affordable to all kinds of players, Yggdrasil allows you to choose a coin value from a range stating at only $0.005 and going up to $5. As the bet is configured to 50 coins, a wager can be anywhere between $0.25 and $250, which is a quite wide betting range allowing both penny punters and high rollers to take their chance on the Power Plant slot.

Adjusting the bet according to your bankroll is all you have to do before you start spinning the reels. You can hit the Spin button or push the Max Bet button and set the stake to the maximum immediately. The Autoplay option is also available allowing you to activate up to 1,000 automatic spins or spin the reels until you stop them.

Bonus Features

As we have already mentioned, the biggest attraction of the Power Plant slot besides its reel structure is Wild. It will replace all other symbols to help you create more winning combinations and win bigger. When it appears in a stack on the reels, not only that it will complete multiple winning combinations but it will also trigger a respin during which you will get additional bonus features boosting your winning chances.

There is a total of 5 bonus features you can benefit from during respins. Between 3 and 8 winning symbols can be added to your reels during a respin and increase your line wins. One symbol can be selected to be superstacked or up to 4 reel nudges can be applied to maximise your win. Besides, one symbol can be selected to be turned into Wild while the last feature activates one of the listed features.

The number of active bonus features depends on the number of stacked Wilds appearing on the reels. If you land only one stack of Wilds, you will get a respin with two bonus features active. Two stacks of Wilds trigger one respin with 3 bonus features whereas 3 and more stacked Wilds activate a respin with 4 bonus features. Bonus features are randomly selected before a respin starts.


Power Plant is a low variance slot with a RTP of 96.1%. The maximum payout is delivered by a five radiation symbols and it stands at 200 coins or 4x your total stake, which is a quite impressive amount taking into account that multiple winning combinations can be created at once. The game is a home to six symbols and the lowest value payout stands at 50.


Power Plant is a perfect fit for the players who are looking for more excitement and it wil surely provide them with an electrifying gaming experience thanks to its impressive graphics and animations. As soon as a possible winning combination is on its way, the winning symbols will be connected with lightnings thus increasing a player’s anticipation. High rollers can enjoy some hefty payouts, but beginners should not avoid the game either as prizes are delivered quite frequently. At least, it is a game developed by Yggdrasil Gaming which is widely recognised for the creativity and excellence when it comes to both visuals and innovative bonus features implemented in the games. This one is really groundbreaking.
