The Symbols

The symbols fall into the space theme. The wild is a swirling vortex and the symbols are all aliens. One-eyed aliens are the low-paying symbols, and two-eyed aliens with horns are the high-paying symbols.


No set amount of paylines, and any cluster of five or more of the same aliens result in a win.

Autoplay Option, Min/Max Bet

You can spin up to 100 times using the autoplay feature. And the turbo mode is activated using the lightning bolt icon. Your betting limits fall between $0.20 and $100.

Reactoonz RTP

Reactoonz has an RTP of 96.51%.


The high volatility of Reactoonz means payouts may be infrequent but sizable.

Gargantoon Quantum Leap

The quantum leap meter fills with each Quantum feature you activate in Reactoonz. Once it’s filled five times, the Gargantoon appears on your reels, first as a 3×3 symbol. With each cascade, the Gargantoon divides into two 2×2 symbols and then nine individual symbols acting like wilds.
