Play'n Go's Reactoonz slot machine is an entertaining space journey with seven rows and seven reels. Eight Reactoonz characters are available in standard form: pink, green, orange, blue, purple, brown, dark green, and yellow. Smaller, one-eyed aliens give out smaller prizes; higher value aliens stick out with two eyes and various horns.
Each of these creatures is somewhat active, moving back and forth, blinking, and glancing at the aliens nearby on a blue background. Both sides of the reels have some sort of extraterrestrial gear, including what appears to be a transporter apparatus.
One 2x2 Giantoonz symbol is created when four occurrences of the same symbol appear next to one another in a square shape. Giantoonz symbols also get a 2x multiplier value, which doubles the value of combinations that contain them.
There is actually a lot to discuss regarding the Reactoonz slot's features. The game features four distinct random modifiers that activate when enough winning symbols are collected in a spin, multipliers, mega Gargantoon Wilds, extra Wilds added from winnings, and random Wilds on non-winning rounds.
A random low, one-eyed symbol is designated as a fluctuating symbol at the start of each spin. Two Wild symbols will be added to the reels prior to a cascade if marked symbols are involved in a victory.
In the event that a spin ends without a win, a random number between 4 and 8 of Wild symbols may be added to the reels in an attempt to produce a win.
Every winning symbol adds to a unique metre. The Quantum Leap progress bar charges by one point for each symbol; one segment of the bar requires 25 symbols to fill. A random Quantum feature is added to the queue once a segment has been filled.
A guaranteed Gargantoon feature is added once the metre is charged five times. Up to four Quantum features can be queued up and kept. When there are no more wins to be had, the features start to activate one after the other.
