The Joker Stacks slots game can be found at casinos offering iSoftBet software. iSoftBet are one of the newer casino software providers on the market but they have managed to tie down some impressive branded slots game contracts. As a standard iSoftBet do not publish the RTP/House Edge information for their slots games within the game help file or paytables. However as part of the UKGC license requirements many UKGC licensed operators have started to publish this information for all of their games. As such we can tell from Trada’s site that the House Edge of Joker Stacks is 3.40% when playing maximum paylines/coins.
Stack those Jokers high!
Joker Stacks is a 5 reel slots game that does not use standard reel layout. Reels 1, 3 and 5 are three symbols high while reels 2 and 4 are four symbols high. This game has 15 paylines and you can bet 1 coin on each payline.
The ‘Jester’ symbol is Wild.
There are two bonus features when playing Joker Stacks. The first bonus feature is activated randomly at the start of any spin and turns either reel 1, 3 or 5 into a Wild reel for the spin.
The second bonus feature is triggered when you receive the ‘Bonus Star’ bonus symbol anywhere on reels 1, 3 and 5. When this happens you will be awarded 15 free spins. During the free spins any Jester Wild symbols will be banked at the bottom of the reels. If you manage to collect 6 Jester Wild symbols reel 1 will be turned into a Wild reel that will remain locked in place for the remainder of the free spins and you will be awarded 2 additional free spins. If you manage to collect another 10 Jester Wild symbols reel 3 will be turned into a Wild reel that will remain locked in place for the remainder of the free spins and you will be awarded another additional 2 free spins. Finally if you collect another 10 Jester Wild symbols reel 5 will be turned into a Wild reel that will remain locked in place for the remainder of the free spins and you will be awarded an additional free spins.
Joker Stacks has an unusual reel layout, a bonus feature that is interesting, though nothing even a moderately experienced slots player will not have seen before and a House Edge is reasonably attractive. Not the best game but not the worst.
