How We Review Slot Games

We test and rate all slot games across 5 criteria, assigning a score out of 10 for each and an overall score that is an average of the 5. To build an accurate assessment of each game we gather information from the supplier and play in real play or demo mode. Find out more.

Dr Toonz is a high variance 6-reel slot from Play n Go. It was the 3rd in the Toonz series of games and uses a 4,096 win ways mechanic instead of the Cluster Pays one from the Reactoonz slots. During the game extra features are unlocked by charging the Quantumeter via consecutive Win Cascades.  3 Charges brings up extra wilds, symbol transformations or symbol upgrades. There is also a free spins round where between 1 and 6 reels are awarded a 2x multiplier, with a possible 64x multiplier on every win.

The top payout is a huge 22,000x and spins start from 10p.

Testing Notes: Here’s What Happened When We Played Dr Toonz

IMPORTANT: To give you an accurate assessment of the games we review our writers play 200 spins. Whilst this is a useful tool to help us review games and to give an example of what might happen when you play, keep in mind that 200 spins is only a very small sample and cannot be used to accurately predict what might happen over another 200 spins. The outcome of all slots play is always random.

Boom Or Bust? Our Session By The Numbers

I played 200 spins on Dr Toonz at Casumo Casino to test the game and this is what happened.

  • Stake Size: £1
  • Start balance: £25,000
  • End balance: £24,930.85
  • Biggest Win: 27.6x
  • Free Spins: 0
  • Session Time: 17 minutes 33 seconds

Playing 200 spins on Dr Toonz was enough to show what it can and can’t do! The free spins round never felt close. I can recall 2 scatters a few times but they were rarer than I expected. Meanwhile, the Quantumeter did at least charge 18 times which is a little under 10%. That might sound tight, but the game did kick out a 27.6x win from a standard base game spin (no modifiers required) when 14 red cyclops dropped on reels 1 to 4. Ok, not huge, but not bad from the base game either, showing you don’t HAVE to break into the big features to get a little love back.

Another Kooky and Fun Addition To The Toonz Collection

It’s not just the reel set and gameplay that is different in Dr Toonz. Far from the intergalactic backdrop of the other Toonz games, this one takes us into the lab of the originator instead. And it turns out Dr Toonz is a mad-scientist intent on winning a Nobel Prize (he tells us intermittently). The lab is a kind of underwater, glass-fronted space. Front and center is a huge rack of test-tubes filled with liquid into which Toonz or other symbols are pumped for each spin. The Dr sits left on a hovering contraption, occasionally muttering about e=mc squared or announcing a feature. He even starts snoring if you leave the reels for too long.

Into the lab of the originator – Dr Toonz

It’s as fun and kooky as you would expect but perhaps not quite as endearing as the original Reactoonz games. And in my opinion, should come with a health warning on the soundtrack which can quickly drive you mad if you don’t find the mute button!

RTP and Variance

Our Score 8

What is RTP?

RTP (Return to Player) refers to the amount a game will pay out in cash prizes expressed as a percentage of all the money wagered on that game. For example, a 96% RTP means a game will pay out £96 for every £100 wagered. This is an average number and will vary from one session to the next.  Read more here.

What is Variance?

Variance refers to how far a game will deviate from its RTP over time. High variance games deviate a lot and produce uneven win distributions and unexpected windfalls. Low variance games provide a more stable and even distribution of wins. Read more here.

You’ll find Dr Toonz, like many Play n Go slots, runs at different RTP settings depending on where you play. The options available to casino operators are 96.25%, 94.25%, 91.25%, 87.25% or 84.25%. You certainly don’t want to be playing at those lower settings and ideally you want to find a site that runs at 96.25%. I checked the RTP at 5 slots sites licensed in the UK. This is what I found.

None of the sites in this sample run at optimum RTP which is not uncommon in the UK. I would recommend playing at Casumo or a White Hat Gaming site like Barz Casino for the next best thing where the game is set to 94.25%.

And it comes as no surprise to fans of this series of games that Dr Toonz is also very volatile, with much of the RTP weighted towards moments in the free spins round where 2x reel multipliers and other feature combinations can bring impressive results.

Maximum Win

Our Score 9

What Is Maximum Win?

Maximum win refers to the maximum amount a player can win from one spin. It is expressed as a multiple of the stake. For example, where the maximum win is 100,000x, from a £1 stake, the maximum win would be £100,000.  

The maximum payout in Dr Toonz is 22,000x which makes it by a long shot the highest paying in the series, far above Reactoonz (4,750x), Reactoonz 2 (5,083x) and Gigantoonz (4,000x).

Symbols and Paytable

Our Score 8

As I have already said, Dr Toonz takes a different direction to the other Toonz slots right from the outset. This is a 4,096 payline slot – no grids, clusters or paylines. In fact it works on a Win Ways basis instead so wins are triggered by landing 3 or more identical symbols on adjacent reels from left to right, regardless of the row position.

The paytable looks decidedly weak at first glance. Even the top paying premiums are only valued at 1x for 6. However, there has to be some way to reach that 22,000x mark, and that is where the powerful modifiers explained below come in.

Dr Toonz Paytable
Paytable with just 2x for 6 premiums and 4x for 6 wilds

First, let’s look at those familiar Toonz. The one-eyed monsters are the low payers as always. They are valued at from 0.1x for 3 yellows up to 0.3x for 6 purples. The two-eyed ones, in blue, orange, green and pink, are valued at from 0.2x for 3 blues up to 1x for 6 pinks.

You also have a Wild that looks like a floating pink orb that will help complete win ways by substituting for pay symbols. They also pay 2x for 6.

Features and Gameplay

Our Score 9

Cascading Wins, Quantumeters and Charge Features

Dr Toonz might not work on the Cluster Pays mechanic of its sibling games but it does utilise our old friends the Cascades and Quantumeter, a charge meter that will trigger features when filled.

Cascades occur after every winning spin – winning symbols are removed from the reels and new ones drop in to replace them. If a new win is triggered, then the process repeats. And so on, until no more wins occur.

The Quantumeter charging in Dr Toonz
A win sends a charge to the Quantumeter

Meanwhile, the Quantumeter sits to the left of the reels, a glowing orb that hovers beneath the Dr who himself is sitting atop some kind of hovering contraption. The orb will be in one of three colors, each representing one of three charge features. At the start of each spin the color of the orb is set, changing each time.

To unlock the feature, the meter must have 3 charges. It starts with between 0 and 2 on each spin, and with each Cascading Win, so 1 more charge is added. You’ll see that the orb grows in size with each extra charge.

The colors of the orb and their charge features are as follows:

  • Blue is a Quantum Wild Charge – when activated, 2 to 6 wilds are added
  • Yellow is a Metamorphosis Charge – when activated, 5 to 8 symbols (excluding wilds and scatters) are transformed into one other symbol. This was the most common charge in testing.
  • Red is a Disintegration Charge – when activated, all low value one-eyed symbols are removed and 2 wilds are added to the reels.

Free Spins With Multiplier Reels

There is a free spins round too, unlocked by landing 3, 4, 5 or 6 Scatters, a kind of swirling multi-colored ribbon. That gets you 10, 15, 20 or 25 free plays – a generous amount I think.

There is nothing too complicated going on here – the rules remain the same EXCEPT that the Quantumeter now starts at 1 or 2 charges on every spin rather than 0, 1 or 2. So, there is more chance of charging it up and unlocking the feature.

But most importantly, between 1 and 6 reels will now have a 2x multiplier appearing at the top, to be applied to all wins that pass through their reel. If all 6 have 2x multipliers, you are in dreamland because you have a 64x multiplier in play at all times (2x2x2x2x2x2).

The Final Verdict

Dr Toonz takes this popular slots series in a significantly different direction by dropping the cluster pays mechanic and simplifying the gameplay. Despite maintaining the Cascading Wins-Charge Meter mechanic this is a very different experience, and to my mind, a simpler one to follow. In making these changes Play n Go may have lost some of the magic of the originals, replacing it instead with a more focused gameplay where you will be simply looking for 3 scatters to unlock the free spins round where there is much more opportunity to score big wins thanks to those reel multipliers and the enhanced Quantumeter on each spin. Having said that, testing showed that you can still land a good win or two in the base game thanks to the 4,096 paylines and the charge features, so don’t be put off.

To conclude, Dr Toonz provides a simpler, if more volatile alternative way to meet with your favourite alien friends, and with a 22,000x prize to play for, who could say no?

Useful Tips When Playing Dr Toonz

Remember, online slots are games of chance, there is NO strategy that can improve your odds of winning. However, reading our review and following these tips will help you get the most out of your time playing this slot game.

1. Keep An Eye On The Quantumeter

Always watch that glowing orb. It sometimes starts at 2 charges meaning you only need one Cascading Win to trigger the feature.

2. Disintegration May Be The Best Charge Feature

Metamorphosis seemed to trigger the most frequently in testing but on paper the Disintegration feature looks the best as it upgrades all low-payers AND adds 2 Wilds. So look for a red Quantumeter charge.

3. Choose A Sensible Stake

Dr Toonz showed his volatility in testing and it makes sense to start with a low-ish stake to avoid burning out too quickly if you want to make it to the free spins round.

4. Choose A Site With A Good Bonus

We recommend the slot sites on this page because they have great value bonuses. You can deposit up to £300 and get a 100% match at Barz Casino to play Dr Toonz for example.
