Slot Details

Game of Thrones Power Stacks is a video slot with 5 reels and 4 rows with 40 fixed pay lines. Wins are awarded for matching three or more symbols on adjacent reels, starting with reel one, from left to right. You can find your favourite series characters from 0.20 credits to 20 credits per spin. Game of Thrones Power Stacks is a game with very high volatility and a default RTP setting of 96.20%. Be aware that Microgaming produces variable RTP versions of their slots and this game will also be found at 94.20% and 92.20%.

Visually this game is outstanding, as you would expect when images, animations and music are plucked straight from the hit TV show. Various landscape stills of Westeros and Essos switch for the background and the music is atmospheric, captures the drama nicely, plus the gameplay is smooth. Theme music from the tv series makes the transition to free spins and cut-scenes grace the wins; a neat addition seen before on Microgaming slots Terminator 2 and Battlestar Galactica. Game of Thrones Power Stacks carries the feel of a premium blockbuster to match HBO’s award-winning series.

Working in ascending order of value, the pay symbols begin with four house sigils from the story; Houses Greyjoy, Stark, Lannister and Targaryen pay up to 2.5x your stake for five of a kind. Five main story characters, Tormund, the Night King, Sansa Stark, Jon Snow and Daenerys Targaryen, captured in portraits from the series, complete the line-up paying up to 7.5x your bet for five of a kind.

Wilds are the GOT emblem and pay 25x your stake for five of a kind and also substitute for all symbols except for the scatter and coin symbols. The throne acts as the scatter symbol and landing three will trigger the free spins. Scatters also pay x1, x10 and x100 for landing 3, 4 or 5, respectively. Coin symbols carry House Targaryen sigils with instant cash prizes from x1 – x30 awarded through the Link&Win feature triggered by landing six or more.

Game of Thrones Power Stacks Slot Features

Slingshot Studios may not be the most frequent name on the tip of players tongues, but one thing demonstrated well in releases such as Banana Odyssey and A Dark Matter is superior graphics and effects. Fitting then, that they should be trusted with a slot conversion for the epic TV phenomenon of Game of Thrones which impressed with its imagery, story and sound. Let’s delve deeper to see if House Slingshot is worthy enough for the Iron Throne.

All symbols except for the scatter and wild symbols can appear on the reels in matching symbol stacks called Power Stacks. For each spin through the base game and free spins bonus, a Power Stack Indicator randomly selects a symbol with a chance to be stacked on the reels.

Landing three or more scatter symbols will trigger the Free Spins Bonus, during which all wins are doubled in value. This round does not retrigger and plays out automatically, only interrupting should you be lucky enough to trigger the Link&Win feature. At the end of the bonus, the sum of all wins is paid.

Game of Thrones Power Stacks Free Spins

Land six or more coin symbols during the base game or free spins round to trigger the Link&Win Bonus Game. This bonus uses a new reel set with only coin and blank positions and begins with a count of 3 respins shown on the counter. The bonus begins by locking the triggering coins in place and using a respin. Any coins landing will lock and hold in place for the remainder of the bonus and reset the respin counter to 3. Should no coins land, the respin counter loses one life. Coin symbols come with cash prizes and one of four fixed jackpot coins:

  • Base Game Coin Symbols – x1, x2, x3, x4, x5, x8, x10, x12 and 15x your bet.
  • Free Spin Coin Symbols – x2, x4, x6, x8, x10, x20, x24 and 30x your bet.
  • Bronze Coin – x20 base game/x40 free spins.
  • Silver Coin – x100 base game/x200 free spins.
  • Gold Coin – x500 base game/x1000 free spins.
  • Valyrian Coin – x2500 base game/x5000 free spins.

The round continues until all 3 respins are spent and will award the sum of all coin values and jackpot coins. Alternatively, filling all 20 grid positions will end the round and award the Valyrian jackpot prize in addition to your accumulated coin wins.

Final Verdict

Game of Thrones Power Stacks is probably the best yet from Slingshot Studios and a great addition to the series, ten years on from the TV pilot and 15 years since the original book. Visually and audibly stunning with just enough features to keep the gameplay exciting. Although nothing extraordinary feature-wise, the combination of free spins, stacked symbols and the hit ‘n’ miss respin bonus is a popular and effective one when executed well and Game of Thrones Power Stacks might just cut the grade in that respect.
