Gigantoonz is Play’n Go’s latest installment in its Toonz slots series featuring cluster pays. Pertaining to its theme, the symbols, and graphics, Gigantoonz follows closely in the style of its prequels, such as Reactoonz. It is also similar to the earlier games volatility and RTP, though some gameplay features have changed and Play’n Go has added some new bonus elements that TheSlotBuzz will examine later in our Gigantoonz review.

Where Can I Play Gigantoonz Slot?


Gigantoonz carries on the legacy of high-paying clusters similar to some of the earlier games in the series, like Reactoonz and Reactoonz 2. As with the Reactoonz games, Gigantooz has a betting range of between £0.20 and £100.

Play’n Go, however, has tweaked some aspects for the better, like the expanded grid for Gigantoonz, but somewhat crippled other elements. For instance, the maximum payout potential for Gigantoonz has been capped at just 4,000x the bet, compared to the 22,000x maximum payout on Dr. Toonz, 5,083x on Reactoonz 2, and even the 4570x on Reactoonz.


With alien symbols that resemble a mix of the ‘Despicable Me’ minions and Monsters, Inc. characters, Gigantoonz is, to say the least, an unconventional slot. But the design of the symbols and the overall game animation is still almost entirely based on the earlier releases.

The alien-like symbols can appeal as regular- or mega-sized, covering multiple slots across multiple reels. The value of the alien symbols can be determined by the number of eyes they have – the more eyes, the greater the value. There are a total of 5 one-eyed and as many two-eyed symbols. The low-paying one-eyed aliens can pay between 5x and 20x the bet, while the higher paying symbols pay between 50x and 1250x, depending on how many you land on. The minimum number of symbols to create a winning cluster is 6, and you can land up to 30, or more, to trigger high wins.

Gigantoonz also provides the so-called ‘Mega Symbols,’ whose size can be between 2×2 and 7×7 the grid. Five to ten Quantum Wild symbols can randomly appear and substitute for regular symbols to form wins. Note, Quantum Wilds can appear only on non-winning spins.


The Gigantoonz RTP is 96.25% However, the theoretical payout rate is changeable and can be as low as 84.25%.

Gigantoonz has a high volatility game model, just as every game in the series. Payouts occur by forming at least 6 or more matching symbols and the game can potentially lead to a reduced maximum win of 4,000x the amount of your bet.


Gigantoonz Symbols

Gigantoonz plays on an 8×8 grid, which is one extra reel and one extra row compared to the 7×7 grid of the Reactoonz games. You can bet manually or automatically by activating the auto spin function. Other highlights include the Quantum Wilds, which substitute all symbols. Up to 10 Quantum Wild symbols can appear anywhere on the reels.


There are no traditional bet ways in Gigantoonz as wins are formed in horizontal and vertical clusters of matching symbols. A minimum of six and a maximum of 30, or more, alien icons can be collected to trigger Big, Super Big, and Mega Big wins. When a cluster wins forms, symbols that make up the win cascade, and new ones drop from the above rows. If it is part of a matching cluster, it will trigger another win, and another, until the winning streak ends.

Those who have played Reactoonz and Reactoonz 2 will not be surprised by the Gigantoonz’s lack of scatter symbols and, effectively, a free spins bonus. Yet the games make up for this popular slots feature with a distinctive component called the Quantimeter, which contains 4 different symbol modifiers.


To the right of the Gigantoonz screen, you’ll notice the slumbering Gargantoon icon. This is the Gigantoonz Quantumeter and it has four separate symbol charges activated when a specified number of symbols activates the charges. Each symbol that forms a winning cluster is one charge and is added to the Quantumeter after a win. With 25 charges, you activate the Disintegration modifier, which picks four different symbol types and discards all instances of those icons on the reel. New symbols then cascade into their place.

With 50 charges, you can trigger the Metamorphoses modifier where one type of symbol and all its instances on the reels are changed into another, unknown symbol. With 75 charges, the Quantumeter can trigger four Mega, and five Quantum Wild symbols. Lastly, 100 charges activate the Gargantoonz modifier, which transforms all Mega Symbols into Mega Gargantoon, then the Mega Gargantoon symbols are fragmented into a number of 1×1 Gargantoon icons.


Gigantoonz is a wacky slot that you can’t seem to stop playing, despite borrowing much from its precursors Reactoonz 1 and 2 and Dr. Toonz. But Gigantoonz also comes with distinguishing features, including an enlarged grid and revamped Quantumeter modifiers and Mega Symbols.
