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.

Reactoonz 2 is a 7×7 Cluster Pays slot from Play n Go and the follow up to one of the studio’s most successful slots of all time. The games uses a Cascading Wins mechanic to build extended sequences of wins during which two meters – Fluctometer and Quantometer – are filled with charges. Filling the meters unlocks additional features including electric wilds that zap other symbols off the grid to trigger more Cascades, and super-sized wilds.

This is a thrilling, high variance slot with a maximum win potential of 5,083x. Spins start from 10p.

Testing Notes: Here’s What Happened When We Played Reactoonz 2

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 Reactoonz 2 at Casumo Casino to test the game and this is what happened.

  • Stake Size: £1
  • Start balance: £25,000
  • End balance: £24,913.6
  • Biggest Win: 11x
  • Session Time: 19 minutes 07 seconds

Playing Reactoonz 2 is always fun and whilst this short test session didn’t yield any spectacular wins, far from it in fact the biggest win was an 11x, it still gave a good account of itself in terms of entertainment value. I counted 15 times when the Fluxometer triggered, adding 1 to 3 extra Electric Wilds to the grid each time. That is 7.5% of spins, and it felt regular enough. The best part by far, without the Quantometer maxing out, were the Wild Pair Explosions, when 2 or more Electric Wilds are left on the grid at the end of the spin. There were 8 of these (4% of spins), and one which cleared the entire grid – see screenshot – as they 2 wilds were adjacent. That is a magic moment and super-charged the Quantometer to unleash Energoon Wilds too.

There is obviously a lot more to that you can get form Reactoonz 2 but the numbers in this test session show that it is a busy game, despite its volatility, and always delivers fun times.

What Our Reviewer Says ...

"A thrilling sequel with the potential do deliver really exciting win sequences if you unlock level 4 with lots of Electric Wilds!"

Overall Score: 8.8

Theme & Design

Our Score 10

A Super-Fun Slot With Action and Re-Action on Every Spin

The design of Reactoonz 2 is very similar to that in the first game. The grid, sitting on top of a swirling electric blue background, is filled with Toonz characters who are as charming and fun as ever, giggling, chatting and fizzing with energy as electric charges fly across the game grid. Wilds looks super cool, like glowing balls of energy as they drop onto the reels, and the two meters displayed to the right of the grid come to life as successive wins charge them up and unlock the sleeping Gargantoon Wilds.

The whole experience is backed with a punchy soundtrack, interspersed with bleeps and buzzes from the grid. In short, it’s a game that grabs your attention and doesn’t let go.

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.

It’s important to remember here that Play n Go are one of those developers who have more than one RTP settings in their games, leaving it to the casino operator to decide which setting to run the game on. In this case there are five: 96.2%, 94.2%, 91.2%, 87.2% or 84.2%. Of course, you want to be playing at the optimum RTP setting if possible – and definitely avoid the lower settings – to give yourself the best chance of winning.

I verified the RTP of Reactoonz 2 at 5 slot sites we regularly use. This is what I found:

This range of RTP settings from different casinos is not uncommon. I recommend playing at MrQ or Barz Casino for the best RTP in this case.

Like the first Reactoonz game, this sequel is a high variance slot so it can swing from cold to hot very quickly, which is one of its many appeals, particularly looking at the configuration of the bonus round.

Maximum Win

Our Score 7

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.  

At 5,083x, Reactoonz 2’s top payout is a long way from being amongst Play n Go’s highest. It is slightly better than the original which clocked in at 4,750x, but a long way behind the kind of epic potential you find in Kiss Reels of Rock (50,000x) or Raging Rex 2 (30,000x) for example.

Symbols and Paytable

Our Score 9

The layout in Reactoonz 2 is the same as the first version, a 7×7 grid. And once again, we have a Cluster Pays format with wins triggered by landing 5 or more identical symbols in adjacent positions touching horizontally or vertically.

Reactoonz 2 Paytable
Paytable with 500x for 15 or more premium pink Toonz

The faces on the paytable will be familiar to anyone who has played the original game as well. There are 8 pay symbols in total – 4 one-eyed (cyclops) Toonz and 4 two-eyed ones. The low payers are in yellow, green, red and pink, valued at from 0.1x for 5 yellows up to 10x for 15 or more pinks. Premiums are in blue, orange, green and pink. Their values range from 0.5x for 5 blues up to 500x for 15 or more pinks. For comparison, the premium pink in the first version of Reactoonz is worth 750x for 15 or more.

And of course, there are also FOUR types of wilds – Energoon, Gargantoon, Electrics and Uncharged. These are a critical element of Reactoonz 2. Each subs in for other symbols to create win clusters. The uncharged wilds become charged on reaction to events on the grid as described below.

Features and Gameplay

Our Score 10

It May Take A Few Plays To Understand Reactoonz 2

A criticism that could rightly be levelled at this game is that it is confusing, particularly on first few plays. There is a lot going on, and several new features have been added on top of what we find in the first version. However, after a few plays (in demo mode I suggest) it will quickly start to make sense.

In simple terms, Reactoonz 2 is all about converting standard wilds into electric wilds and filling the two meters to unlock further wilds and bigger wilds. All of which will help you to build bigger clusters and score better wins.

Throughout the game you have the Cascading Wins mechanic that helps to keep things rolling along. Here, after any win, winning symbols are removed from the reels and new ones drop in to replace them. If more winning clusters are formed, then the process repeats. And so on, until no more wins are formed.

After each sequence comes to an end the two meters re-set and you are back to the start.

The Fluctometer and Building Electric Wilds

To the right of the grid, at the top, you have the Fluctometer. This will help you to earn extra wilds to help build clusters.

The Fluctometer Unleashing Wilds

On each spin, one of the Reactoonz symbols from the paytable becomes a fluctuating symbol. If one of the fluctuating symbols is part of a winning combination, then it converts into an Electric Wild AND a space on the Fluctometer is filled.

Once the meter is filled completely – there are 11 charges on it – then between 1 and 3 Electric Wilds are added to the grid.

What are Electric Wilds? These can substitute for all other symbols but they also perform magic when two appear on the grid. A charge form between them causing them to zap normal Reactoonz symbols off the reels to trigger further Cascade action.

Quantometer Has FOUR Levels And FOUR Features

Also to the right of the grid, and sitting under the Fluctometer, is the Quantometer.

This one gets filled with one charge every time a Reactoonz symbol is zapped off the grid by an Electric Wild. There are four levels on the meter. Each time the meter fills to the required level, then another kind of Wild is released onto the grid.

Electric Wild Added To The Quantometer

Level 1 is reached at 55 charges. FOUR additional Energoon Wilds are added to the grid.

Level 2 is reached at 85 charges. A 2×2 super-sized Energoon Wild is added to the grid. Now, 30 charges are discounted from the meter.

Level 3 is reached at 110 charges. A 3×3 Gargantoon Wild is added to the grid. It breaks down into 2 2×2 wilds and finally 9 1×1 wilds IF it is part of a Cascade.

Level 4 is reached at 135 charges. A 2x multiplier is applied to ALL wins AND Gargantoon Wilds are now in play on the grid too.

Wild Pair Explosions Cause Bigger Avalanches

One of the most exciting features of the game is the Wild Pair. This only activates at the end of your Cascade sequence and when there are two or more Electric Wilds left on the grid.

If the two Electric Wilds are next to one another, then all other symbols bar wilds are removed. If they are not next to each other, then only symbols between them and surrounding them are removed. Those symbols that are removed add charges to the Quantometer so this can massively boost your charge level and help you to add more wilds to the grid and potentially trigger more wins.

The Final Verdict

I really enjoyed this game. Despite initial reservations about the complex features and triggers, it quickly became easy to follow. The best way to find out is to start playing for yourself and you’ll soon learn it. The objective always is to charge the Quantometer as far as possible simply by removing Reactoonz from the grid either by Cascading wins or with Electric Wilds reacting with each other. The further you go, the more exciting it gets with bigger wilds dropped on the grid and more electric wilds in play. What impressed me most is that despite its high volatility, it never felt like a tight game. Most spins produced a win and Cascade sequence of some kind, even if many were cut short before things got really interesting. And with such an entertaining interface, even the small wins are fun.

Personally, I think there is enough difference between this and the original Reactoonz to make it worth your while. Or courses, it would have been even better if Play n Go had powered-up the max win still further, and I advise to keep an eye on the RTP wherever you play, but otherwise Reactoonz 2 is well deserving of its high score here.

Useful Tips When Playing Reactoonz 2

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. Play In Demo Mode First

Reactoonz 2 is a game that benefits from a few rounds in demo mode first to help you to understand how the meters and electric wilds work together to trigger those wins.

2. Look For The Fluctuating Symbol Before Each Spin

Check the Fluctometer to see which symbol is a fluctuating one before each spin. These are the ones you want to appear in clusters so they convert to Electric Wilds and fill the meter.

3. Play At 20p Per Spin

If you want to give yourself the best chance of seeing the big features then play the game at a low stake like 20p per play. Remember, this is a volatile game so it can burn you very quickly.
