Dr Toonz Review

Those cheerful little critters are back, and it’s time to meet the guy who created them in the Dr Toonz slot from the team at Play’n GO.

The sci-fi theme creates the perfect bonkers backdrop for another outing of the now-familiar Reactoonz characters. This time, the key differences come in the game’s bonus features and stats with the potential to boost the ways to win up to an impressive 262,144 during the free spins round. Will this latest slot in the series be a scientific marvel or an alien nightmare? Read our full review now to find out!

Dr Toonz Bonus Features

Although Dr Toonz isn’t quite as packed to the rafters with bonus features as the other slots in the Reactoonz series, there’s still plenty going on here. The cascade feature can provide multiple wins on every spin, while charging up the Quantumeter will trigger 1 of 3 modifiers to give the base game an extra boost. You can also trigger the game’s main bonus feature with up to 25 free spins, plus land x2 Payway symbols above all the reels for an epic 262,144 ways to win.


Look out for the wild symbols, which feature valuable slot features and will substitute for any paying symbols to give your spins a little boost. Plus, if you can land 6 on a payline you’ll get a 2x your stake reward.


A DNA like structure represents the scatter, and landing 3, 4, 5, or 6 of them will reward you with 10, 15, 20, or 25 free spins and trigger the feature.

Cascade Feature

Landing 3 to 6 matching symbols or wilds from the leftmost reel creates a win, and any symbols involved will disappear from view. This allows new symbols to cascade down from above to fill in the gaps, potentially forming multiple wins from just 1 paid spin.

Quantumeter Charge Modifiers

The Quantumeter makes a welcome return and contains between 0 and 2 charges at the start of each base game spin, with winning cascades charging the meter by +1 each time. Once it’s full with 3 charges, it activates after the current cascade ends to give you one of the following modifiers: Quantum Wilds – up to 6 wilds appear in random positions. Metamorphosis – up to 8 regular symbols transform into another type. Disintegration – all one-eyed alien symbols are removed and 2 wilds are added.

Free Spins

Once you’ve landed enough scatters, the free spins round triggers and the Quantumeter kicks off with up to 2 charges on every spin. Unfortunately, there is no way to retrigger the free spins round. At the top of each tube, x2 Payway symbols can randomly appear during the feature to double the number of winning ways on that chosen reel. Should these land above all the 6 reels, you’d be playing that spin with a mighty 262,144 Payways.

Dr Toonz Jackpot

The Doc hasn’t engineered any jackpots in his amazing looking lab, but you could still create a max win of up to 22,000x your bet by triggering all the right features.

RTP and Volatility

The significantly higher max win potential when compared to the previous Reactoonz slots gives it a higher volatility rating too. In terms of the RTP, the best you’ll experience is 96.25%, but it can be lower as it’s a variable rate, so always check before you play.
