Where to play?

iSoftBet’s Joker Stacks is an upbeat 5 reel, 15 payline online video slot that’s laced with colourful HD (High Definition) visual animations. Regrettably it’s not in the same league as NetEnt‘s Jackpot 6,000, basically it’s a classic slots with a modern look.

Essentially it’s the ideal game for low rollers while high-limit players might ply their trade elsewhere. Why? Because the maximum bet per spin is only £15. The smiling joker is responsible for all the action as it turns reels into wilds during the main game and there’s a free spins feature that awards 15 free spins.

”Joker Stacks has 5 reels that are 3x4x3x4x3 rows high, it’s an entertaining slots with an upbeat soundtrack and a fresh glossy look.”

Symbols on the reels are cherries, watermelons, lemons, jester wilds, horseshoes, blue and red 7s, gold star (bonus) and bells. A couple of lemons pays 40x your stake and if you’re lucky enough to collect 5 red or blue sevens at the maximum stake the rewards can be a spectacular 150 coins. The RTP or average return to player percentage of Joker Stacks is 96.7% which is quite high up on the payout scale – expect loads of low paying spins.

Bonus Modes


The smiling joker is the wild symbol, it substitutes symbols adjacent to it to form a winning combination bar the scatter. It also turns any of reels 1, 3 and 5 into a stacked wild bonus known as the ‘Sticky Stacked Wild Jokers’ feature.

Free Spins

The scatter symbol or bonus symbol is the yellow star, 3 of them triggers the free spins feature which awards 15 free spins. They only appear on reels 1, 3 and 5. Once you’ve accumulated 6 jester symbols (wilds) it transforms reel 1 into a fully stacked wild plus an extra 2 free spins will be added making it 17 in total. It’s a progressive free spins feature meaning that 2 extra free spins will be added should you notch up another 10 jesters – the fifth reel becomes a fully wild reel too.

To Recap, the free spins with a normal wild are awarded in this manner:

  • Collect 16 wilds, 2 free spins will be added, reels 1 and 3 becomes wild until the conclusion of the free spins.
  • If you’re lucky enough to collect 26 wilds not only will you receive an extra 2 free spins but reels 1, 3, and 5 will become wild. Believe us when we tell you collecting 6 wilds is a feat in itself.



Joker Stacks is a generous slots during the base game and even more so during the free spins with the potential of transforming the third reel into a fully wild reel. In theory the slots looks great but it kinda sucks (pardon our French) in reality. Only play it when you really have nothing else to play.
