KISS slot review

Theme and Storyline

This slot is themed on the infamous ‘70s band KISS.

With splattered face paint, extended tongues and plenty of attitude, this game leans into the spirit of rock ‘n’ roll.

The unmistakable style of KISS is stamped on this game with the animalistic expressions of rockstars. The glamorously anguished aesthetic will give fans a pang of nostalgia.

Players are presented with a stage-like set of reels framed in industrial metal. Instead of just watching though, they’ll take part in the performance with each spin.

Graphics, Sounds and Animations

The game’s rock soundtrack only plays upon spins which keeps it from becoming tiresome. Wins are celebrated with a cheerful mini guitar solo. However, the music is sometimes out of sync with particular actions which takes away from the drama.

The sound doesn’t quite capture the immersive intensity of KISS, but it adds some upbeat dimension to the gameplay.

The symbols range from glowing letters to the band members’ iconically painted faces. This contributes to the feeling that the reels are a stage and the band is performing as symbols.

The darkened backdrop has the atmosphere of a concert and nicely sets off the neon glowing signage.

This slot has two sets of reels. The Main Reel Set has five reels and four rows. The Colossal Reel Set has five reels and eleven rows.

There are a total of 100 win lines between both reel sets. Players receive wins on multiple paylines added together.

The players’ total bet is equally split among every active payline.

Win lines are awarded left to right and must occur on adjacent reels. Players cannot apply win lines from reel set to the next.

Players will only collect the highest winner paid per winning combination on each set of reels.

Wilds, Bonuses and Free Spins

The Wild symbol substitutes for all symbols except the Feature symbol.

Players can only land the Feature symbol on the Main reels 1, 3, and 5, as well as the Colossal reels 1, 3, and 5.

The Free Spin Feature is awarded when players land three or more scattered Feature symbols across both reels.

  • 3 Feature symbols - 8 free spins + x2 total bet.
  • 4 Feature symbols - 12 free spins + x5 total bet.
  • 5 (or more) Feature symbols - 20 free spins + x20 total bet.

While in the Free Spins Feature, one or more Wild symbols from a stack appearing on a reel of the Main Reel Set will trigger the rest of the stack to fall into place. This will make all four reel positions on that reel Wild. Then, the Wild will transition to the Colossal Reel Set. This will make that corresponding reel Wild.

Throughout the Free Spins Feature, an alternate pair of reel sets is used.

Bet Sizes, RTP and Variance

The return to player of this game is 95.94%, nearly exactly our yardstick for average of roughly 96%.

The range of bets on the site we tested ran from a minimum bet per spin of $/£/€0.10 up to a maximum of $/£/€500 per spin. Adjusting the bet size can be tedious as it must be done at small intervals manually. High rollers may find this especially irritating.

The volatility of this game is high, which makes it a good match for our preferred slot machine strategies. Our slot strategies target the highest possible volatility.


We do not recommend this average RTP, high volatility rock-themed slot.

With a nostalgic rock’n’roll theme, and reasonable strategy stats, most players will find this WMS game worth the stop.

A few design issues such as bet-setting and music timing also take away from what could have been a very engaging slot.
