Game of Thrones™ Power Stacks™ Online Slot

Yes it’s true! We’re coming back to the world of Westeros and the battle for the Iron Throne in the stunning online and mobile casino slot – Game of Thrones™ Power Stacks™. Available at Spin Casino Online Casino, this epic video slot based on the much-loved HBO series, Game of Thrones℠ is an action-charged online slot that celebrates the show and some of its dazzling locations and favourite characters.


What’s more, it introduces the exciting new Power Stacks™, while also featuring the Link&Win™ Bonus, Coin Prizes and Free Spins. Stunning graphics and soundscapes compliment the theme – no surprise as it’s powered by Microgaming, in collaboration with Slingshot Studios: two of the most acclaimed software providers around. Additionally, the riveting Game of Thrones™ Power Stacks™ is optimised for all compatible devices, so it looks and sounds great whether one is playing on a PC, laptop, tablet or smartphone.  


Let’s take a closer look at what this online and mobile slot has to offer players.

Design, Theme and Basics

Played across 5 reels, 4 rows and 40 paylines, Game of Thrones™ Power Stacks™ is infused with characters, visuals, and music from the landmark series Game of Thrones℠. The result of a collaboration between legendary game developer Microgaming and exclusive provider Slingshot Studios, this online slot is emblematic of their attention to detail and quality products.


A high volatility video slot, Game of Thrones™ Power Stacks™ has an RTP of 96% and a total hit frequency of 29.63%, while its minimum bet is 0.20 and maximum bet is 20.00. Features include Power Stacks™, Link&Win™, Coin Prizes, and Free Spins. Adapted for all compatible desktop, tablet and mobile devices, this online slot can be played with either credits or coins.


Taking place in Westeros, the design of the game is instantly recognizable – with the iconic Wall and its snow-covered locale serving as the backdrop. Familiarity should resonate even further with the appearance of some of the most popular characters from the show on the reels.


An exceptional game, this 2021 release is certainly a welcome addition to Spin Casino.

Epic Symbols

The low-yielding symbols in Game of Thrones™ Power Stacks™ are represented by the banners of the Great Houses – House Stark, House Targaryen, House Lannister, and House Greyjoy. They’re joined by the high-value symbols, represented by characters like Jon Snow, Daenerys Targaryen, Sansa Stark, and Tormund Giantsbane.


Then we have the Wild and Scatter symbols, signified by the game logo and Iron Throne, respectively. The Wild has the power of substitution, meaning it can replace other standard symbols to complete possible winning combinations. The only symbols it cannot replace are the Scatter and Coin symbols. The Wild can also appear stacked during the Free Spins feature, while the Scatter and Coin symbols are integral in activating some of the coveted features.

Exciting Features

There was no shortage of thrilling moments in the HBO series, Game of Thrones℠, and the same is true of this enthralling online and mobile casino slot.


On the left-hand side of the reels, players will notice a carousel – referred to as the Power Stacks™ indicator. Here, a standard symbol is randomly selected per spin to display. This symbol can become a Super Stacked symbol for the related spin, which also means that players can potentially land a fully stacked version of that symbol on all 5 reels simultaneously. Notably, the only symbols that cannot be selected are the Wild and Scatter symbols.


The Link&Win™ Bonus feature is activated when one lands 6 or more Coin symbols on one spin. The Coins are then held in position while the player receives 3 Respins on a fresh set of reels comprised only of Coins and blank spaces. If a new Coin symbol appears, it’s also held and a reset of 3 Respins occurs. Each Coin symbol has an attached value – during the base game, the values range from 1x up to 15x, however, during Free Spins the values can go even higher: up to 30x. The coin values are then added up to give the player a Bronze, Silver or Gold Prize – 20x, 100x, or 500x the player’s stake, respectively. If the player attains a full screen’s worth of coins, they can potentially win the Valyrian Prize, which is 2 500x the player’s stake. If this feature activates during Free Spins, the prizes are worth more, which we’ll discuss further below.


The Free Spins feature is activated by landing 3 Iron Throne Scatter symbols on reels 3, 4 or 5, resulting in 15 Free Spins being awarded. All potential wins during this feature are subject to a Multiplier of 2x. This means that the Coin Prizes in Link&Win™ are also doubled – so the Valyrian Prize becomes 5 000x.
