Gigantoonz slot

The release of the Reactoonz slot was a milestone not only for Play'n Go but for the cluster grid genre as a whole. Since then, the developer has had success with Reactoonz 2 and Dr Toonz, but so far none of these releases have been able to outshine the original. Gigantoonz is closer to the original than the previous 2 installments and looks less complex which fans can appreciate. In today's review, you will learn about all the details of this game, its bonus features, volatility, RTP, max win and we will also add a few words about its design so stay with us!

How to play

The playing field has been expanded to 8 reels in 8 rows, and now you regularly get up to 7x7 Mega Symbols. They can charge Quantumeter up to +13 for 1 symbol. The gauge can trigger 3 normal modifiers, as well as the Gigantoon Mega Wilds modifier, which tops things off in a 2 step process.

You only need to do a few things to start this cluster grid frenzy:

  • Open Gigantoonz at the casino of your choice
  • Click on the menu button to read the rules
  • Select bet: from €0.20 to €100
  • Spin the reels!

Gigantoonz RTP and Volatility


High risk comes with 96.25% RTP.

One-eyed and two-eyed cartoons will delight you with the creation of a cluster not as often as you would like since the game comes with high volatility. But, each cluster will bring a large payout. The RTP is 96.25%.



During the launch of the game, you will see a cool introductory video that talks about Reactoonz, multi-colored cartoon monsters that get bigger and bigger over time. The voice from the screen will tell you that they should now be called Gigantoonz as they are bigger than ever! Next, you will see a purple background on which there is a large playing field. To the right of the reels is the Quantumeter which is charged with the help of winning symbols.

The paytable has 5 one-eyed toonz as low-paying symbols and 5 two-eyed toonz as premium symbols. You will receive a payout when 6 to 30 or more matching symbols land in a cluster anywhere on the playing field. All winning symbols will then be removed and replaced with new and/or existing symbols and this process will repeat indefinitely as long as you win. You can get 5-10 Quantum Wilds on random dead spins and they will be randomly distributed across the reels to help complete the clusters.

Bonus Rounds & Free Spins

Mega Symbols

Mega symbols can land on the playing field quite often and they come in sizes from 2x2 to 7x7. They count as 1 symbol in combinations, but the "cluster value" is determined by a random number up to 13. Once removed from the grid, Mega Symbols leave Quantum Wilds and if they can't fall below, they transform into standard 1x1 symbols.


All symbols that participate in a winning cluster charge the Quantumeter which is located to the right of the playing field and all regular symbols give as 1 charge. Mega symbols are considered their "cluster value" and once the meter gets 100 charges in 1 cascade you get 4 modifiers in chronological order. We will start with the first 3 since the last one deserves a separate description:

  • When 25 charges are collected, Disintegration is triggered, which removes all copies of 4 randomly selected symbols
  • When 50 charges are collected, Metamorphosis is triggered, which turns all copies of a randomly selected icon into another type of icon (including mega)
  • When 75 charges are collected, Radiation is triggered, which randomly adds 1-4 Mega Symbols and 2-5 Wild Symbols to the playing field

When the meter is filled with all 100 charges, the sleepy monster above the meter finally wakes up to activate the 4th modifier. It is played in 2 stages:

  • Stage 1 transforms all Mega Symbols into Mega Gargantoonz symbols, and you get at least 3 Mega Gargantoonz Symbols anyway which are not removed upon winning. On top of that, you also get 2-4 Wild Gargantoonz of regular size 1x1
  • Stage 2 breaks the Gargantoonz Mega Wilds into 1x1 symbols and then removes them with the cascading wins feature just like standard symbols

Max Win


Catch modifiers and win up to 4,000x!

The 3 common modifiers we discussed above can have a big impact on the outcome of the game as they keep your winning streak going and it will definitely end with a big bang when you can charge the meter to the end. The advertised max win potential of 4,000x is less than its predecessors but quite fun to reach and the max win probability is 1 in 4,850,000 which is pretty decent!

Overall Rating


Previous slots have made things a bit more complicated than the original and we're glad that Play'n GO is back to basics with Gigantoonz. Of course, the big difference is the mega symbols, which have random cluster values, and they can be quite useful when it comes time to charge the Quantumeter. Most of the time you get the first 2 modifiers, but the tension really escalates as you get closer to getting giant mega wilds. The first 3 modifiers can make a big difference in the outcome of the game as they keep your winning streak cascading and it's sure to end with a bang if you reach 100 charges in the meter! All in all, this is a pretty entertaining game that fans of the original are sure to enjoy.

Mega symbols up to 7x7
Up to 10 Quantum Jokers after random dead spins

Another edition of Reactoonz. The main concept remains the same – cascading mechanics, cluster lines, explosions, random features after collecting a certain number of winning symbols.
The unique part of the game is Giant symbols. They can be as big as 7x7. They are not just big, they also carry additional multiplier.
The game is volatile and unpredictable. It can take some time before u get a decent payout. But it will happen, eventually.
