Some say the Game of Thrones show is overrated, some that it’s immersive and fun, while others say that books are still superior. No matter which side you’re on, it is still hard to deny that Game of Thrones made a huge impact on our culture and especially the media. So it's no surprise we have a prequel coming up, and a bunch of games: from table ones to PC and of course, slots! One of them is Game of Thrones Power Stacks, released on 10/08/2022. Here in addition to enjoying the fantasy atmosphere from the beloved show, you can also enjoy other goodies: Free Spins, Special Symbols, Multiplier and even the Link&Win feature with 4 available jackpots!

How to Play

The first thing you need to keep in mind is that Game of Thrones Power Stacks has a Link&Win feature, and some newbie players may be on alert hearing that, thinking that this feature may be something complicated. But in reality, it is very simple to understand, and we will cover it in more detail below. But briefly, this feature is sort of like a re-spin mode, meaning that the feature will reset itself once you land a certain number of symbols. And during the Link&Win feature, you get a shot at 4 available jackpots.

Other than that, Game of Thrones Power Stacks is rather simple to learn how to play, especially if you played similar slots with the same game set of 5 reels, 4 rows and 40 paylines.

  • To get started, find the casino you are going to play in and launch Game of Thrones Power Stacks
  • Press the triple bar and then plus/minus symbol to adjust the value of coins per line and coin size. overall the minimal total bet is €0.20 and the maximum value is €20
  • Without leaving the menu next click on the “i” button, where you need to familiarize yourself with the rules of the game and the value of symbols
  • To begin the game click on the middle, spin button on your right next to the reels!

Game of Thrones Power Stacks RTP and Volatility

7.8 

Game of Thrones Power Stacks is a video slot with very high volatility and a 96.20% RTP.

The first thing we need to address is that this is a slot with very high volatility. so expect that getting a winning symbol combo will be rather tricky, but that also means that you will get a much bigger payoff for the said combo. This is the volatility we recommend mostly to experienced players that prefer a high stake playstyle. Other than that, Game of Thrones Power Stacks also has a very decent Return to Player rate - 96.20% - and this is just about average for many video slots!

Theme

8 

Game of Thrones Power Stacks slot is directly inspired by HBO’s phenomenal TV show, adapted from George R.R Martin’s amazing series - A Song of Ice and Fire. So here you will not only see the main characters from Game of Thrones but will also see the design and even hear the same music as in the show.

Specifically, in the background, you will see the Wall, where no doubt Jon Snow keeps his watch while contemplating how much he doesn’t want to be king. The reels are well-made and their design is apparently influenced by the iron throne. Oh, and there is also an official Game of Thrones score, playing in the background, specifically the Targaryen theme, which is very epic.

Now as for the symbols, all of them display some Game of Thrones-related imagery. You have 11 symbols (plus 4 types of coins) - 2 special and 9 regulars. The regular symbols are the crest of Greyjoys, Starks, Lannisters and Targaryens and these are the lowest paying symbols in the game. Then there are symbols with Tormund, the Night King, Sansa, Daenerys and finally Jon. Special symbols are Scatter, Wild and coins. The Wild symbol is the Game of Thrones logo and it can substitute for all other symbols except Scatter and coin symbols. Wilds are also stacked in the Free Spins feature and have the value of 2.50x, 5x and 25x if you collect 3, 4, or 5 symbols. The Scatter is the iron throne symbol and if you collect three of them it will trigger 15 free spins. other than that scatter has a value of 1x, 10x and 100x for the 3-5 symbol combo.

There are also additional symbols aka coin prizes. You have bronze, silver, gold and valyrian coins, that have various multiplier awards, which you can get in both the base game and Free Spins round.
