Game of Thrones Power Stacks: Slot Overview
‘We are going to leave the world better than we found it.’ Daenerys Targaryen said that before later laying waste to King’s Landing, only to be stabbed by her lover and blood nephew Jon Snow, aka Aegon Targaryen. Depending on where you stand, Dany’s destruction was either the best or the worst possible way to close out the remarkable Game of Thrones saga. Either way, most can agree that, at its peak, the show was a full-blown cultural phenomenon. With that in mind, it’s hardly shocking to find the feuding houses of Westeros splashed across everything from Night’s Watch Boyfriend Pillows to life-size Iron Throne replicas, and naturally – slot games.
The GoT-branded slot under the spotlight comes from Microgaming partner Slingshot Studios. Microgaming has tackled this universe before, having launched the massive hit Game of Thrones 243, plus a 15-payline edition, back in 2014. Slingshot’s newer entry, Game of Thrones Power Stacks, takes the theme and charges ahead with it like a Lannister host fleeing an angry dragon. The action begins at the base of The Wall, where a 5×5, 40-payline reel set sits in front of the enchanted barrier that shields the living from Night Walkers lurking in the far North. Around the reels, you can already spot hints of what’s ahead, including Link&Win, several jackpots, and Power Stacks. Once free spins finish, the scenery shifts – King’s Landing, the heart of Westeros’ rule, becomes the second backdrop to appear.
Fans should enjoy the chance to return to Westeros, made even stronger by the excellent soundtrack lifted from the series. The iconic opening theme, for instance, had us buzzing during free spins, while tracks such as Blood of my Blood from season 6 helped keep the base game feeling charged. As far as branded slots go, this is a very confident use of the license.
‘When you play the game of thrones, you win, or you die‘, Cersei Lannister famously warned. Game of Thrones Power Stacks isn’t quite that ruthless, but it is highly volatile and it also comes with a hefty max win. There are multiple RTP setups available, with the highest offering a theoretical return of 96.20%. Beyond the adjustable RTP, each version also shows tiny variations in hit rate, though they all sit around 29%, or roughly 1 win in 3 spins. You can get your GoT fix on any device, with stakes ranging from 20 p/c to $/€20 per spin.
The paytable keeps the Game of Thrones flavor front and center as well. Four major house sigils serve as the low symbols – Greyjoy, Stark, Lannister, and Targaryen paying 2 to 2.5x the bet for five on a line. Above them are five standout characters from the story: Tormund Giantsbane, the Night King, sharp-eyed Sansa, Dany, and the man who knew nuthin’, Jon Snow. Hitting five matching character symbols delivers 5 to 7.5 times the stake. When premium wins land, players also get a slick series animation as a bonus treat. The game logo acts as the wild and triggers a quick animation whenever it helps form a win. It can do so by replacing other paying symbols or by forming wins made entirely of wilds – paying up to 25x for five of a kind.
Game of Thrones Power Stacks: Slot Features

The Power Stacks indicator appears in the left corner and randomly displays a symbol type. That chosen symbol becomes Super Stacked for the current spin, with stacks applied across all 5 reels. Any symbol other than scatters or wilds is eligible to be Power Stacked.
Scattered among the standard symbols are special coin symbols. When 6 or more appear, they activate the Link&Win feature. The triggering coins lock in place, and every other symbol is cleared from the grid. Then 3 spins begin, with any new coins resetting the counter and also locking into position. The feature finishes when the spins are used up or when the Valyrian prize is collected. Regular coins carry values from 1x to 15x the stake, while special coins stand for the 4 jackpots. These are bronze, silver, gold, and Valyrian paying 20x, 100x, 500x, and 2,500x the bet, respectively.
Hitting 3 Iron Throne scatters in the base game grants 15 free spins. In free spins, all values are boosted by x2 – including Link&Win payouts, since the Link&Win can also trigger during free spins.
Game of Thrones Power Stacks: Slot Verdict
If you’ve been waiting for a reason to return to Westeros, Slingshot Studios offers a pretty convincing one. The developers have used the theme extremely well, not only in the obvious elements like the scenery, but also in smart details such as making Valyrian steel the top jackpot tier. Game of Thrones Power Stacks feels like it was built by dedicated fans for players who’ll appreciate those touches. In short, if you have any affection for the show, you’ll likely feel at home as George R. R. Martin’s world ignites on your screen.
Stepping away from the theme briefly, it’s fair to say the features aren’t wildly groundbreaking. The Link&Win, which also appears in Thunderstruck Wild Lightning, for example, has a more imaginative twist there, and the idea of doubling free spins wins isn’t exactly new. But does that really matter? When a slot lets you revisit one of the best TV series ever made, originality in the mechanics becomes less important. And it’s not as if the rewards are Flea Bottom-tier. The Valyrian prize in free spins, for instance, comes in at a tidy 5,000x, while the overall max win reaches 25,000 times the stake – which tops the earlier GoT slots, if you were curious.
Slingshot has absolutely nailed the branding. Game of Thrones Power Stacks brings a lot of the show’s weight and atmosphere onto the reels, treating the source material with respect while still keeping things fun. The visuals are impressive, the music is outstanding, and while the features may not scream innovation, they can still pay off. Non-fans, or anyone soured by the finale, may feel differently, but as Jon Snow put it, ‘We look up at the same stars and see such different things.’
