The Game of Thrones Power Stacks slot is played using 5 reels, 4 rows and 40 fixed paylines. Winning combinations are created in the usual manner by landing 3, 4 or 5 matching symbols or wilds from left to right across a payline, starting from reel 1 (the leftmost reel).

Theme – Audio and Design features – join Jon Snow and the Night King in this official game
Theme: Game of Thrones TV Series
High Value Symbol: Wild
Compatibility: Mobile, Tablet, Desktop
The design in the Game of Thrones Power Stacks slot will be instantly recognizable to anyone who has seen the Game of Thrones television series. This is an official branded game created by Microgaming with permission from HBO. This is the second slot based on the hit TV series as Microgaming released Game of Thrones way back in 2015.
Graphically, Game of Thrones Power Stacks is much better than the original game. The first thing you will notice is the sweeping orchestral soundtrack from the show itself. For Game of Thrones fans, it’s the Blood of My Blood song composed by Ramin Djawadi and used in 6th episode of Series 6. As you’d expect from a high-profile TV adaptation, the design here is excellent.
With the Wall in the background, the lower value symbols feature the banner emblems for Houses Greyjoy, Stark, Lannister and Targaryen. They’re joined by 5 higher-paying character symbols. You have the Wildling, Tormund Giantsbane, the Night King, Sansa Stark, Daenerys Targaryen and Jon Snow. Jon Snow is the highest value symbol paying 1.25, 2.5 or 7.5 x your total stake for 3, 4 or 5 across a payline.
The Game of Thrones Power Stacks logo is the wild symbol. This can appear on all 5 reels and substitute for all the standard symbols in a winning combination. Land 3, 4 or 5 wilds on a payline for a payout of 2.5, 5 or 25 x your total stake. Rounding out the symbols is the Iron Throne which is the scatter. Here is a table showing the payouts per symbol:
|House Greyjoy Emblem||3, 4 or 5 = 0.35, 1 or 2 x stake|
|House Stark Emblem||3, 4 or 5 = 0.35, 1 or 2.2 x stake|
|House Lannister Emblem||3, 4 or 5 = 0.5, 1.2 or 2.4 x stake|
|House Targaryen Emblem||3, 4 or 5 = 0.5, 1.25 or 2.5 x stake|
|Tormund Giantsbane||3, 4 or 5 = 0.6, 2 or 5 x stake|
|Night King||3, 4 or 5 = 0.75, 2.1 or 5.5 x stake|
|Sansa Stark||3, 4 or 5 = 0.9, 2.2 or 6 x stake|
|Daenerys Targaryen||3, 4 or 5 = 1, 2.25 or 7 x stake|
|Jon Snow||3, 4 or 5 = 1.25, 2.5 or 7.5 x stake|
|Logo Wild||Substitutes for all symbols above|
|Iron Throne Scatter||3+ triggers Free Spins feature|

Game of Thrones Power Stacks Bonus Features
There was no shortage of action in the Game of Thrones TV series and the same is true of this high-octane slot adaptation. With 4 bonus features, extras on offer here include super stacked symbols and free spins with a 2x multiplier. There’s also the streak re-spin-style Link&Win feature where you could scoop a bumper jackpot prize of up to 5,000 x stake.
Power Stacks feature
To the left of the reels, you’ll see a carousel. This spins on each spin to reveal a symbol. The revealed symbol will be the Power Stack which will appear in fully stacked formation for that spin. Known as the Power Stacks feature, ny symbols apart from the wild and scatter can be selected to be the Power Stack.
The Link&Win feature is triggered when you land 6 or more coin symbols on the same spin. Those coins are held and 3 respins are awarded on a new set of reels made up solely of blanks and coins. If a new coin lands, it too is held and the respins reset to 3.
The features ends when you’ve used up all your respins. You’ll notice that each coin comes with a cash value attached. In the base game, these values vary from between 1 and 15 x your total stake. Trigger during the free spins and the prizes can get as high as 30 x stake. Finally, the value of the coins is added together to give you an overall prize.
Also joining the action here are Bronze, Silver and Gold coins which award an associated fixed jackpot. Known as the Jackpots feature, this is what they pay:
|Jackpot||Base Game||Free Spins|
|Bronze||20 x stake||40 x stake|
|Silver||100 x stake||200 x stake|
|Gold||500 x stake||1,000 x stake|
|Valyrian||2,500 x stake||5,000 x stake|
To trigger the big Valyrian Jackpot, you’ll need to fill all the positions on the grid with coins. Manage this from a base game trigger and you’ll win a 2,500 x stake payday. Get the full house from a trigger during the free spins and the payouts is a massive 5,000 x stake. Lastly, these jackpots come on top of any standard coin wins.
Free Spins feature
The Game of Thrones Power Stacks slot also comes with a Free Spins feature. To trigger it, land 3, 4 or 5 Iron Throne scatter symbols on the same spin. This will reward you with a payout of 1, 10 or 100 x your total stake. You will also receive 15 free spins with a 2x multiplier. As a result, you will hear the Game of Thrones theme song.
More importantly, wild symbols will be stacked during the free spins. This is crucial as the wild is the highest paying symbol. Lastly, you can trigger the Link&Win feature during the free spins which double the payouts offered in the base game (see table above).
Game of Thrones Power Stacks Review Summary – a feature-filled trip to the Wall
The Game of Thrones Power Stacks slot may not be Microgaming’s first game from the iconic TV series. The features stack up really well, offering some cracking variety. The super high volatility means that it can pack a real punch too.
Compared to the original Game of Thrones slot, the design is much, much better. It actually features characters from the series like Jon Snow, Sansa Stark, Daenerys Targaryen and the Night King. The RTP is higher. Furthermore, the max win of 25,000 x stake is also higher (20,250 x stake max win in the original).
When it comes to payouts, a screen full of wild symbols will result in a 1,000 x stake win. With the doubling multiplier in the free spins, the max win would be 2,000 x your total stake. However, it’s the Link&Win feature where the biggest wins will come from as you can win fixed jackpots up to 5,000 x stake (in the free spins). This extra is also used in Thunderstruck Wild Lightning (also by Microgaming).
Overall, it’s a good game which is visually superb. The soundtrack is as epic as the TV series (can you tell I’m a huge fan?). If you’re a fan of the series, Game of Thrones: Power Stacks is a must-play slot.
- Superb visuals/audio including characters + music from TV series
- Big 25,000 x stake max wins possible
- Good variety of bonus features
- Bonus features offer nothing we haven't seen before
