Dr Toonz Slot (Play'n GO)

The Dr Toonz slot plays on 6 reels and 4  rows and offers 4,096 paylines. The game uses a pay model called Dynamic Payways, which was developed by Play ‘n GO. Wins come from matching 3 to 6 symbols starting from the left reel, and crossing any of the paylines across adjoining reels.

Bets for this game start at 20p and go up to £100. You can adjust your bet amount using the plus and minus buttons at the bottom of the screen. Non-UK players can utilise the Autoplay function, which goes up to 100 spins. There’s also a Fast Play option to speed up the spins.

The RTP rate is 96.25%, which is above the online average for slot games. There are also 94.25% and 91.25% options available. 

You’ll find a high volatility, and it scores 8 out of 10. And the maximum win is an impressive 22,000 times the bet.

The Dr Toonz slot revolves around a quirky scientist working in a submerged laboratory. Once a respected physicist, Dr. Richard Toonz was cast out by the scientific community for pursuing his belief in creating life forms through unconventional means - and he succeeded spectacularly!

The game’s grid is cleverly set within his underwater lab, surrounded by test tubes filled with life forms. Dr. Toonz himself navigates in a small flying device, bringing his playful energy to the screen. He encourages you to “c’mon” when you pause spinning and starts snoring if left idle. With a thick German accent, he occasionally exclaims about Nobel prizes, adding to his character.

There are well-placed scientific touches like the scatter that looks like colourful DNA string. There is a cool backstory to the game as  Dr Toonz is the inventor of the creatures from the Reactoonz slot game series, which you may be familiar with.

Cute space-like music plays in the background, and the sound of the creatures dropping into the water is heard a lot as they cascade down the grid.

On the reels are various cute-looking critters, here's a rundown:

• Yellow One-Eyed Alien: 3, 4, 5 or 6 = 0.1, 0.15, 0.2 or 0.25 x bet
• Green One-Eyed Alien: 3, 4, 5 or 6 = 0.1, 0.15, 0.2 or 0.25 x stake
• Red One-Eyed Alien: 3, 4, 5 or 6 = 0.1, 0.15, 0.25 or 0.3 x stake
• Purple One-Eyed Alien: 3, 4, 5 or 6 = 0.1, 0.15, 0.25 or 0.3 x stake
• Blue Two-Eyed Alien: 3, 4, 5 or 6 = 0.2, 0.25, 0.35 or 0.5 x stake
• Orange Two-Eyed Alien: 3, 4, 5 or 6 = 0.25, 0.3, 0.4 or 0.6 x stake
• Green Two-Eyed Alien: 3, 4, 5 or 6 = 0.3, 0.35, 0.45 or 0.75 x stake
• Pink Two-Eyed Alien:3, 4, 5 or 6 = 0.4, 0.45, 0.5 or 1 x stake
• Orb Wild: Substitutes for all symbols above
• DNA Scatter: 3+ triggers the Free Spins feature
  
  

Dr Toonz Mobile

The Dr Toonz mobile slot is powered by advanced HTML5 technology, which means you will enjoy an excellent gaming experience on both Android and iOS devices. It's fully optimised for play on tablets and desktops as well.

The Dr Toonz slot has 5 bonus features to offer, including cascading reels,  3 Quantumeter features which transform symbols and add wilds. There is also a Free Spins feature where up to 25 free spins can be awarded.

Quantumeter 

The Quantumeter starts is next to the grid and starts at 0 to 2 charges on each base game spin. Whenever there is a winning combo and cascade, it charges the Quantumeter by 1, up to a maximum of 3. Once the Quantumeter is fully charged, the features are triggered and each feature has its own colour:

• (Blue) Quantum Wilds: adds 2 to 6 wild symbols to the reels

• (Yellow) Metamorphoses: transforms 5 to 8 symbols to another symbol (wilds and scatters excluded)

• (Red) Disintegration: removes all 1-eyed alien symbols and adds 2 wilds to the reels

The Quantum Wilds and Disintegration features add wilds to the reels. This is known as ‘Dynamic Payways’ and this increases the number of ways to win. In theory, you can land 8 symbols per reel, giving you 262,144 ways to win.

Free Spins 

If you land 3 or more DNA scatter symbols, the Free Spins are awarded.

• 3 DNA scatters = 10 free spins
• 4 DNA scatters = 15 free spins
• 5 DNA scatters = 20 free spins
• 6 DNA scatters = 25 free spins

As in the base game, the Quantumeter comes into play, but with free spins, it starts with 1 or 2 charges on every free spin.

Cascades

Every time there is a winning combo, the symbols are removed from the grid, and new symbols drop down, filling the empty positions. This can lead to more winning combs and the process keeps repeating until there are no more wins.

I appreciate a slot game with a strong storyline and I love that we’re given the back story to the Dr. Toonz slot. We are told that “Dr Toonz is on the cusp of discovering the secret to creating new life forms, more commonly known as ‘Reactoonez”. By the way, this is a fantastic slot series, which you can read more about in this guide to the Reactoonez slot guide.

Charging the Quantumeter was a highlight, as watching it grow with every spin added excitement. The 3 possible features triggered frequently during testing, with the Quantum Wilds and Disintegration features delivering the best results. The extra wilds mean that the ways to win can increase up to a staggering 262,144. Starting with up to 2 charges per spin during the Free Spins feature significantly impacted gameplay and made it a highlight of the game.

Dr. Toonz’s quirky character, complete with his German accent and iconic sayings like “E = mc²,” brought him to life as the quintessential mad professor. He’s reminiscent of another famous German scientist you might have heard of!

This is the highest-paying slot in the Reactoonz series, with a whopping 22,000x max win and a decent  RTP of 96.25%. If you enjoy space or alien-themed slots, you’ll also love games like Space Invaders by Inspired Gaming,  Fire my Laser by Hacksaw Gaming, or Play’n GO’s Reactoonz - created right in Dr. Toonz’s lab.

With its superb bonus features and immersive design, Dr Toonz scores a solid 4 out of 5. For more Play 'n GO options, check out our guide to their best slots, comparing RTPs, max wins, and more. And if you’re ready for more ‘Toonz’ fun, try Gigantoonz or Gargantoonz next.
