Gigantoonz Slot Machine – Free Play & Review

The Toonz series is comprised of several excellent slot machines, including titles like Reactoonz and Dr. Toonz. Regardless of the exact focus and angle that they each have, they have in common the same alien-like creatures which show up among their symbols. We see them here as well, in the same two sizes.

The low-paying symbols are easy to recognize, since they’re the ones with one eye. Adult aliens have two eyes, and they’re used for the premium symbols. The Gigantoonz are also major symbols that could show up. Both regular and mega symbols can land, of all types, and they can end up taking over up to 7×7 positions.


Play n GO has worked hard to build up its reputation. They have their fair share of boring themes in their collection, but the majority of their slot machines are going to have at least interesting features or big rewards, so there is always something there that makes them worth checking out.

How To Play It

It’s coming with a full betting range of $0.20 to $100, and the values to choose from will all be listed at the bottom of the screen. Use the arrows, left and right, to navigate through them.

The setup is comprised of 8×8 reels, with a total of 64 symbols which land each spin. Thanks to the Cluster Pays system that’s used, you just need matching symbols to appear next to each other, at least 6 of them adjacent horizontally or vertically, and you get paid. For the best payouts, you need at least 30 symbols in a cluster.

Special Features

An avalanche mechanic is included, so the winning symbols always go away, and others drop in to occupy empty positions.

Sometimes, symbols will appear in a mega form, meaning that they take over multiple spots. They range from 2×2 to 7×7 in size. Regardless of size, they count as one symbol when forming clusters, but they have a value of up to 13x attached, which tells you how much they contribute to the cluster’s prize. As a mega symbol drops after a win, it leaves behind a wild.

The Quantum Wild is a substitute, and it shows up at random, after losing spins. Up to 10 of them can be added to the reels.

Through drops, you will contribute symbols to a Quantumeter, which will charge up. At certain milestones, ranging from 25, to 50, 75, and then 100 charges, there will be certain features which will trigger. These need to charge within a single round, across multiple cascades.

  • Disintegration, where 4 types of symbols are chosen, and then removed from the reels.

  • Metamorphosis, to pick one type of symbol, which is then transformed into a different one.

  • Radiation, with up to 5 Quantum Wilds and up to 4 mega symbols added to the reels.

  • Gargantoonz, which starts by turning mega symbols into mega Gargantoonz Wilds (guaranteed to get 3+ such symbols either way) and also adding up to 4 regular sized wilds. The next step is to turn the mega wilds into regular ones.

Maximum Payouts

For the sort of high volatility that’s expected of it, Gigantoonz doesn’t actually pay all that much. 4,000x the stake is the top prize, and as usual you can expect the RTP to change at certain developers (up to 96.25% is possible).


Gigantoonz has the lowest payouts of the Toonz series, though it’s not too far away from the Reactoonz slots. If you enjoyed the other games, then this one is going to be worth playing as well.
