WMS is famous for their innovative approach to slot making, and some of their games include truly unique and revolutionary features never used before by other software developers. One of these features that is much loved by slot fans is known as the Colossal Reels engine implemented in this reviewed game. The long and short about this feature is that there is the main reel set with 5 reels and 4 rows, and the Colossal reel set with 5 reels and 12 rows, both are integrated into and visible on the gaming screen.

The Kiss slot is inspired by the legendary hard rock band of the same name that was founded back in 1973 and still gathers thousands of adoring fans with their live performances. The slot has 100 paylines, the number of which is changed in increments of 20. The minimum and maximum bets in the game are $0.5 and $250, which makes it very appealing to both low-limit players and high-rollers.

Bonus features

There are two key features in Kiss that can improve your odds of winning greatly. Wild Transfer is the first highly rewarding feature that can pay immensely when active. To launch the bonus, you need to hit four wild symbols stacked on any of the five reels on the main reel set. Should this happen, the corresponding Colossal reel will become fully wild, too.

The Kiss logo acts as a scatter that appears on reels 1, 3 and 5 across both reel sets and unlocks a certain number of free spins. Hitting three, four or five scatters awards 8, 12 or 20 free spins respectively. If during the feature a partial stack of wild symbols lands on the main reel set, it will automatically nudge up or down to appear fully and then transfer itself to the Colossal reel set.
