Gigantoonz Slot Game Background

Play'n GO has released a large selection of games through the years that has built its reputation as one of the biggest developers in the industry, with over 300 slot games from Play'n GO available to play with all of the best online casino sites worldwide!

Giganatoonz Game Design

Gameplay of the Gigantoonz slot takes place in a similar setting to that of the classic Reactoonz slot; the main difference is an additional row and reel, so the grid has an 8x8 layout. The background in Gigantoonz shows a deep space scene with a huge swirl of purple matter floating through outer space, while the rest of the play screen showcases sci-fi-style features alongside the entertaining alien character symbols. A fast-paced electronic soundtrack accompanies gameplay in Gigantoonz in keeping with the fun display and components of the reels in play.

Gigantoonz Mobile

Fans of Gigantoonz gameplay will be glad to hear that this slot is compatible with multiple devices, from desktop PCs to smartphones and tablets, and this common feature of new UK slot games offers the same brilliant play design and mechanics with a range of internet-connected devices.

Giagnatoonz Slot Symbols

Like its predecessor, Gigantoonz uses a cluster pays mechanic in which landing 6 or more symbols that form a cluster on the grid rewards a payout.

The low-value symbols that players can form clusters with here involve all of the one-eyed aliens in play; for some reason, the number of eyes in Gigantoonz relates to the value, and these can return 10x, 20x, or 30x the bet stake when clusters of 30 or more symbols in a single spin.

The greater value symbols comprise all the 2-eyed alien symbols in play that hold a value of between 50x and 1,250x the bet stake!

There are also quantum Wilds that players can land across the play grid in Gigantoonz!

Gigantoonz Bonus Features

The popular cascading reel feature is included in play here; players can land further symbol clusters from a single spin by replacing all symbols involved in combinations. It is also possible to land Mega symbols in each base game spin of Gigantoonz; these symbols land 2x2 - 7x7 large, and these Mega symbols leave behind quantum Wilds if they form a cluster; these symbols can also land at random in play and substitute for base game symbols in clusters when they do.


In the absence of a Scatter symbol, the main bonus feature in Gigantoonz is triggered with a Quantumeter to the right of the play grid: any symbol that forms part of a cluster adds to this Quantumeter, with 100 symbols added to the metre from one single spin and its subsequent cascades to present all 4 modifiers, and these are unlocked as more symbols get added to the metre and include the following features.

  • 25 Symbols = the Disintegration features remove 4 random symbols from the play grid.
  • 50 Symbols = the Metamorphosis feature transforms a single symbol from the grid into the same matching one.
  • 75 Symbols = the Radiation feature adds between 1 and 4 random mega symbols and 2, 3, 4 or 5 random quantum Wilds to the play grid.
  • 100 Symbols = the Gargantoonz feature wakes the 3-eyed alien from their slumber and turns all mega symbols on the grid into the Gargantoon Wilds; this modifier adds between 2 and 4 Gargantoon Wilds to the play grid that is not removed in the cascading reels when they form a cluster. The mega Gargantoon Wild symbols also remain sticky in the cascading reels and get smaller until they become 1x1 in size. They then get removed from play.

Gigantoonz Slot Summary

The great variety of bonus features that Play'n GO has included in Gigantoonz help to set this slot apart from the original. The same cluster pays mechanic, and entertaining alien symbols make this Gigantoonz slot just as popular (if not more so) than its predecessor. If you fancy some payline-based slot play, check out the Big Bass Splash or Gates of Olympus slot at Lottomart.
