Dr Toonz Slot

Play’n GO’s Reactoonz series gets its third instalment by way of a prequel that shines a light on the origins of the provider’s wacky creations. Dr. Toonz shows how one mad scientist’s ideas gave rise to a new form of life along with two immensely popular online slots – is the origin story as good as what came after? You’ll have to read on to find out!

From the outset, you’ll notice Play’n GO has opted for a change of layout. Instead of the grid-based slots we’re used to, Dr. Toonz plays out across 6 reels, 4 rows and an initial 4,096 ways to win, which can eventually increase up to a staggering 262,114. There’s also an alteration to the pay structure. As opposed to utilising the cluster pays mechanic, this new slot awards wins whenever 3 or more matching symbols appear on adjacent reels, starting from the leftmost reel.

There is familiar ground to walk upon though. The Quantumeter makes a return, along with its host of symbol charge features. Huge win potential is also once again available, with a maximum of 22,000x your stake up for grabs. What’s even more exciting though is that there’s also a traditional free spins feature included!

Dr. Toonz Features

A key draw to the previous slots in the Toonz series is that they’re packed full of special features and Dr. Toonz definitely fits the bill in that regard. A myriad of base game bonuses help to generate considerable payouts, whilst the new free spins bonus unlocks the game’s true payout potential.


Like most modern slots, Dr.Toonz includes a Wild symbol to improve your chances of securing a payout. It substitutes for all regular paytable symbols when landing in conjunction with at least one winning combination.


Any winning combination triggers the cascade feature. Winning symbols disappear from the reels to leave space for new ones to drop in and potentially create additional payouts. The process continues until no more combinations land.

Quantumeter & Features

On any base game spin, the Quantumeter will start at 0-2 charges. Each win increases the meter by +1 and you’ll need 3 charges to activate one of its three features, which you can identify by the following colours:

  • Blue – Quantum Wilds: adds 2-6 wild symbols in random positions.
  • Yellow – Metamorphosis: transforms 5-8 regular pay symbols into another symbol type.
  • Red – Disintegration: removes all one-eyed symbols and adds 2 wilds to the reels.

Note that only one Quantumeter feature can trigger per spin or free spin.

Scatter Symbol

You’ll need to land 3 or more double helix scatter symbols to trigger the new free spins on Dr. Toonz. However, the more scatters that land in view, the more free spins you’ll receive, as outlined below:

  • 3 Scatters: 10 free spins
  • 4 Scatters: 15 free spins
  • 5 Scatters: 20 free spins
  • 6 Scatters: 25 free spins

Dr. Toonz Free Spins and Bonus

The true potential of this prequel lies within the free spins bonus, courtesy of the 2x multipliers that can appear above each reel. On each free spin, 1 or more reels are guaranteed to reveal a 2x multiplier, which doubles the win amount of symbols on that reel. Land all 6 multipliers and you’ll be looking at a 64x multiplier, which effectively maxes out the number of ways to win at 262,114!

Additionally, the Quantumeter now starts with 1-2 charges on each free spin thus improving your chances of triggering the various modifiers. However, scatter symbols are not present during the bonus, meaning you cannot retrigger the free spins feature.

Dr. Toonz Theme and Symbols

Dr. Toonz neatly captures the theme of both earlier releases and slightly expands on it. Here, we see where it all began – an underwater laboratory, where the mad scientist himself is keeping a close eye on his creations.

Symbols flow into each reel’s chamber via one of the titular character’s curious inventions, which again underpins the overall aesthetic. Paytable-wise, you’ll come across the same strange creatures – the one-eyed versions offering smaller wins, whilst the larger variants serve up more substantial payouts – the pink creature is the game’s premium symbol, offering a full return on your stake for each instance of 6 of a kind. 

Dr. Toonz RTP and Volatility

Dr. Toonz comes with a respectable 96.25% RTP, helping it to clock in slightly above average when compared to other online slot games.

In terms of volatility, it’s classified as a high variance release. Therefore, like the other titles in the series, patience is going to be key when going in search of much larger payouts.

How To Play Dr. Toonz

Given Reactoonz 2’s complicated gameplay, you could be forgiven for thinking this release is just as complex. Thankfully, it’s anything but. The transition to a reel-based pay structure allows new players to quickly come to terms with what’s going on. Equally straightforward is the manner in which you trigger the various features; either hit successive wins or land a certain number of scatter symbols.

Each function you’ll need sits below the reels, including the spin button, autoplay functionality, paytable information and betting options. The stake limits themselves range from the £0.20 minimum bet to the jaw-dropping £100 maximum bet.

Slotsia’s Review

We believe Dr. Toonz is a solid addition to Play’n GO’s Toonz slot series. It may take time for returning players to make the adjustment to the altered layout and pay structure but novice spinners will likely welcome the changes with open arms.

Feature-wise, it certainly resembles the earlier releases, with a myriad of special bonuses available to trigger on any given spin. However, two elements truly make this release stand out. The first is the addition of a traditional free spins bonus with huge potential multipliers and the second is the enormous maximum win potential – 22,000x soars above the previous titles in the series. Overall, Dr. Toonz is a slot that’ll keep you well entertained as you go in search of those mega payouts!
