The graphics have a noticeable upgrade, especially the background. This US slot now feels more cosmic and galactic. The multiplier trail is visible on the left side, tracking your cluster wins.
Despite the changes, the appeal of the adorable, big-eyed Toonz remains. This slot keeps the original unique charm.

Reactoonz 100 Symbols & Payouts
The symbol pays are split between four low-pay one-eyed Toonz and four high-pay two-eyed Toonz. Clusters of 15+ high-pay symbols can net up to 100x the bet. Wilds substitute for all symbols. The key addition is the win multiplier, applied to clusters containing an Energized Toon. One-eyed wins add 1x to the multiplier; two-eyed wins add 3x.

Reactoonz 100 Bonuses & Features
Winning symbols fill the Quantum Charger meter. Every 25 symbols charge a queued feature, up to four random ones. The fifth charge is always the Gargantoon.
Quantum Features trigger when cascades end. They include Implosion, Incision, Demolition, and Alteration. These can transform symbols, add wilds, or destroy low-pays.
The Gargantoon is the grand finale, appearing as a 3×3 wild block. It merges from smaller 1×1 wilds into 2×2, then finally the large 3×3 wild.
Also, look out for Instability on non-winning spins, which can drop 4 to 8 wilds. The Fluctuation feature makes a random one-eyed symbol add two wilds to the grid if it’s part of a win.

This is one of the titles that Play’n GO is shuffling out in its special 100 series, as an homage to vintage slot titles. Veteran players will like seeing these games reworked, but it’s still fresh for new players.
Keeping it “100”: Reactoonz is Worth a Look
I love the reworking of the background screen: it’s updated, brighter, and entertaining. I like to play a 7×7 grid, which isn’t as common in slot games these days.
My favorite part of this title from Play’n GO is the Gargantoon feature, which can boost wilds quickly, just like that. It keeps you on your toes while playing this online casino game.
