Game of Thrones Power Stacks Slot Review

HBO’s Game of Thrones series was such a big hit that it easily branched out in other media. Comics, upcoming TV show spin-offs, and action figures were all part of the huge deal signed between HBO and the books’ creator George R.R. Martin. It didn’t take a long time after the first series premiered for the world of Game of Thrones to arrive in the slot industry.

The first Game of Thrones slot was released in 2014. As a matter of fact, the Isle of Man studio released 2 versions of it. One came with 15 lines, while the other had 243 ways to win. They were both a huge hit, leaving fans wanting more. It may have taken Microgaming nearly a decade, but the studio came back to the world of Westeros with a bang releasing Game of Thrones Power Stacks. It became part of the Games Global portfolio in 2022 after a huge acquisition deal.

As the name obviously explains, this is a slot that uses the Link &Win mechanic. It has 40 paylines, unlike its predecessors, and an RTP of 96.2%. The winning potential has been upped as well. With the right symbols and multipliers, you can win up to 25,000 times your bet in the Game of Thrones Power Stacks slot.

Game of Thrones Power Stacks Slot Setup and Paytable

The Game of Thrones Power Stacks slot has a rather familiar 5x4 reel set. It’s set against the icy areas North of Winterfell. That’s an ominous setting on its own, so you should be ready for an undead wild attack.

In terms of symbols, you can expect to see the full character cast. The show’s logo is the Wild and the highest-paying symbol as well. Five Wilds on a payline can deliver a win of 25x your bet. You’ll also see each house’s sigils, as well as special coins that trigger the Link&Win feature.

The controls are situated to the right, while the left side is reserved for the Power Stacks symbol. Whichever symbol appears in the lower-left corner is chosen as the Stacked symbol that can land on all 5 reels on the next spin.

The game’s imagery and audio, and sound effects are on par with the HBO show, so this slot offers the full package.

Game of Thrones Power Stacks Slot Gameplay

To start your fantasy adventure, you should place a bet between $0.2 and $20 per spin. The main game plays just like you expect it to. This is a highly volatile slot game where you link 3+ symbols for winning combinations. All wins pay from left to right, so when it comes to the base game gameplay, it’s pretty straightforward.

That’s before the Power Stacks and Link&Win features come into play. As mentioned, there’s a carousel with different symbols in the lower-left corner. The symbol that appears on it is chosen to appear as Power Stacks. All symbols can be chosen to expect for the Wild or Scatter. If you’re lucky for the fully stacked symbol to fill the screen, you’re in for a massive payout.

Six or more golden coins on the screen will trigger the Link&Win feature. Once active, you get 3 respins with the coins held in place. The new reels used in this feature only hold blanks and coins. Land a new coin, and the respins will be reset to 3.

Every coin during this feature has a cash value attached to it. In the base game, the maximum payout is 15x your stake, but it can double during the free spins round.
