Reactoonz has been one of the most popular slots for a few years — and now in 2022, you can play a brand new sequel, Gigantoonz. And oh boy is it a doozy of a slot game. Also developed by Play'n GO, this title takes everything players loved about Reactoonz and dials that up to 11. There are more reels and rows (8×8 this time) and more bonus mechanics like mega symbols and cascading Wilds. Although, saying that, the maximum win potential here of 4000x is actually slightly less than in the last entry in the series, Reactoonz 2. It might interest you to know, however, that the developers actually upped the maximum win of that game by some 1000x after seeing the community reaction. So who knows if that could happen here? We sure hope so!

What Gigantoonz is all about

Gigantoonz slot is a highly-volatile, mile-a-minute, grid-based slot, with loads of characters. Classic three-reel players aren't the main target audience here, that's for sure. There's a lot that can go on (visually at least) with any one spin, so keep your wits about you while you play this one. You'll see Mega Symbols that go up to 7×7 and almost fill the screen. You get Quantum Wilds, which drop in bunches of up to 10. Each time you get either of those, the Gargantoonz meter fills up. Get it to the top levels for potential multipliers and Mega Gargantoonz, which stick around for several spins before breaking up into smaller Mega symbols. Phew!

Cascading Reels

The key feature in Gigantoonz is the cascading reels mechanic. This is a format you'll find across many slots. But, in case you didn't know, it means each time you win, those symbols disappear and new symbols drop in. These can also form wins, in which case the process repeats. This can keep going until you don't get any more winning clusters. Sweet! Watching a big Mega Symbol toon cluster, more on that below, disappear only for a new one to come dropping in is certainly cool! Although having said that, Cascading Reels is hardly a brand-new slot feature for 2022 and many players will have seen it before. Unlike many cascading reel slots, Gigantoonz doesn't offer multipliers after each cascade win either — but it makes up for that with Mega Symbols and Wilds.

Mega Symbols & Quantum Wilds

As you might expect, Mega Symbols are giant symbols. They certainly take up a lot of space, especially when they pop up in 6×6 or bigger forms! They aren't worth the exact amount of reel space they cover though, as you might think. Instead, they're given a random value between 5x and 13x. Mega Symbol clusters can also fall in to replace other symbols during a cascading win. They are replaced with one row of standard Toons of the same value if they fall off the bottom reel. The Quantum Wilds function in the same way as Wilds do in other slots. That is, they substitute for any other symbol when making a winning line (or in this case, cluster). Each Mega Symbol also drops a Wild onto the reels when it disappears after a win.


The main draw, and the highest win potential feature in Gigantoonz, is the Quantumeter. Each winning hit, you lucky devil, adds 1 charge on the meter. If you hit a Mega Symbol, you gain charges equal to the cluster value. The meter goes up to 100 and each time you hit the milestones of 25, 50 or 75 you get an extra effect. At 25, four random symbols are disintegrated and new ones drop in. At 50, all of one particular symbol (including Megas) will become a higher paying one. For 75 charges you'll get up to four Mega symbols and 5 wilds dropped in. At 100 charges, a guaranteed three mega symbols appear — and two Gargantoonz. These special mega symbols stick until they hit the bottom row, and if they win they explode into Wilds. Nice!

Gigantoonz Summary: A Gigantic Sequel?

Gigantoonz is an interesting slot game from Play'n GO. The Mega Symbols are a great addition and make for some cool gameplay moments. However, the fact that their size doesn't correspond to their value can create some disappointment. Seeing a 6×6 symbol cover the whole screen and then only payout 5x is a bit odd in our opinion! Still, Gigantoonz is a game with a lot going on. The Quantumeter, and its unpredictable craziness, can add some real wow moments to your gameplay experience. If you're a simple, old-school slots fan, there are better games available for you. But if you like games with animations, a super-high variance and massive combo potential — then Gigantoonz could be up your street. Definitely a solid entry in the Toonz series of slots!
