Theme and Graphics

If you played Microgaming’s original Game of Thrones slot, you might have been a little bit disappointed with the overall look. It was just way too simple for such a tremendous theme, but Game of Thrones Power Stacks really changes things up with a much more impressive design.

In Slingshot's Game of Thrones Power Stacks slot, there is much more to look at. In addition to the sigils for the main houses of Westeros, there are also symbols that depict the most popular characters. Sansa Stark, Jon Snow, Daenerys, Tormund and the Night King are the game’s picture symbols, as well as a fiery iron throne.

So, if you’re a fan of the Game of Thrones series, this is the game that is more likely to pique your interest.

How to Win

There are 40 paylines in Game of Thrones Power Stacks and wins are created by landing three or more matching symbols on any line. The game’s logo is the wild and the iron throne is the scatter which pays out a 100x prize.

Power Stacks

The Power Stacks feature is new to slots from Microgaming Studios but you will have seen similar features in games like Mystery Museum and Golden Goddess. Any symbol except the bonus symbols or the wild can appear in stacks to help you land generous prizes.

Link & Win Bonus

The main bonus feature is a Link & Win round – similar to the bonus round you’ll find in the Money Train series. After triggering the bonus with three scatter symbols, you’ll be taken to a new screen with a counter set at 3 and a whole new set of symbols.

The symbols that can land are only jackpot symbols (bronze, silver, gold and valyrian) or coins with cash values on them. Whenever you land a symbol, the counter will reset to 3 – and, the bonus only ends when you’ve filled the reels or the counter hits 0.

Game of Thrones Power Stacks Free Spins

There is also a free spins bonus in that can be triggered by landing three or more scatters. During this round all wins are doubled.

It’s not the most amazing free spins round out there. However, it’s pretty impressive that Slingshot Studios managed to include one alongside all of the other Game of Thrones Power Stacks bonus features.


As we mentioned earlier, there are four jackpots available in this game. You can win them during the bonus round or base game, and it just takes one of the jackpot symbols to trigger its associated prize. The payouts difference in the base game and bonus round:

  • Bronze: 20x in base game, 40x in bonus
  • Silver: 100x in base game, 200x in bonus
  • Gold: 500x in base game, 1000x in bonus
  • Valyrian: 2500x in base game, 5000x in bonus

Game of Thrones Power Stacks Slot Review

We appreciate that there is now a selection of Game of Thrones slots on the market. Even though the series ended in 2019, it’s still a hugely popular show that made a tremendous impact on the world of entertainment.

So, it’s great that players have a couple of options when it comes to slots based on the Game of Thrones. While the original game was more traditional, Game of Thrones Power Stacks brings different features to the table that will appeal to more modern players.

Are Power Stacks Worth a Mention?

The idea of Power Stacks isn’t all that novel, so it’s a bit confusing as to why Slingshot chose to use the feature in the game’s title. Stacked symbols aren’t a new thing in the slots market, and they don’t make all that much difference in the gameplay of this slot.

Other Bonuses Shine

However, the rest of the bonus features in the Game of Thrones Power Stacks demo are top notch. You can never go wrong with a Link & Win-style feature – especially when there are impressive jackpots at stake, as well. All this, on top of a free spins bonus, as well!

The fact that you can trigger the jackpots in the base game is another big selling point of this game. It keeps things interesting even outside of the bonus, so you can something to look forward to.

Is It Worth a Spin?

In this Game of Thrones Power Stacks slot review We highly recommend playing it. The game offers players a fun experience and a design that really stands out from Microgaming’s first Game of Thrones slot. If you prefer a more traditional slots experience, then the original game might be more suited to you, though.
