The famous Iron Throne serves as the scatter symbol. Find two to trigger a random cash prize. Find more than that and it will activate the Free Spins feature. You'll then be given the choice of 4 features, each based on one of the famous Houses of Westeros and each offering something a little different.
The Baratheon Bonus offers 8 free spins and a 5x multiplier. The yellow Baratheon banner will also become a three stack symbol for the duration of the bonus. Opt for the Lannisters and you'll be awarded 10 free spins and a 4x multiplier plus a four stack symbol. The House Stark bonus offers 14 free spins and a 3x multiplier in combination with a five stack symbol. Finally there's House Targaryen which will give you a whopping 18 free spins with a 2x multiplier and a six stack symbol.
The goodies can keep on coming as extra free spins are on offer if three Wild Game of Thrones symbols appear during the feature. If you're lucky enough to hit the trifecta of free spins, wilds and big multiplier the results can be pretty spectacular. It's possible to win up to 20,250 times your stake on a single spin in the 243 ways to win version!
Game of Thrones also comes with a standard gamble feature which is available after any win. It's a simple heads or tails choice which offers you the chance to double your win. You'll also get to see clips from the show during this round. Both the 15-payline and 243 ways to win versions of Game of Thrones are in the medium range in variance. You're more likely to find bigger wins in the base game in the 15-payline version. The 243 ways to win version comes into its own more in the free spins. It's a case of horses for courses really.
As you'd expect from a collaboration with HBO, Game of Thrones looks and sounds great. The intricate banners of each House of Westeros are superbly detailed and all the action on the reels plays out to the famous Game of Thrones theme (which is brilliant).
The slot version may not lack the X-rated sex and violence of its television predecessor. There's still plenty to enjoy though, especially thanks to the free spins. And with a maximum payout of 20,250 times your stake, there's more than enough treasure on offer to keep the Iron Bank happy! If you like branded slots, Microgaming also offer Jurassic Park which is also superb. However, if you like slots based on television series, The Sopranos by Playtech is pretty good.
