For entertainment only. Wins are virtual credits and cannot be cashed out.
Gigantoonz is Play'n GO's cosmic cartoon slot, a sequel in the Reactoonz family that drops quirky alien creatures onto a giant 8x8 cluster-pays grid. Its extras are oversized Mega Symbols, the Quantum Wilds they leave behind and the Quantumeter, which charges up through four escalating modifiers.
Game mechanics
Wins form when enough matching symbols land connected on the 8x8 grid, with no traditional paylines. Each winning cluster is cleared and fresh symbols drop in to replace it, which lets one spin chain several wins in a row.
Mega Symbols from 2x2 up to 7x7 land on the grid and count towards clusters. When one is removed, it leaves Quantum Wilds behind that substitute for all paying symbols. Winning symbols also charge the Quantumeter, which unlocks its modifiers at 25, 50, 75 and 100 charges.
Features
- Mega Symbols. Giant symbols between 2x2 and 7x7 in size land on the grid and are counted as part of clusters.
- Quantum Wilds. When a Mega Symbol is removed after a win, it leaves Quantum Wilds behind that substitute for every paying symbol in follow-up cascades.
- Quantumeter. Winning symbols charge the Quantumeter; at 25, 50, 75 and 100 charges it fires the Disintegration, Metamorphosis and Radiation modifiers on the way to the top feature.
- Gigantoon Mega Wilds. The Quantumeter's fully charged reward: a two-step feature that places permanent Mega Wilds on the grid for the remainder of the sequence.
Why Gigantoonz has five RTP settings
Play'n GO's own game data for Gigantoonz lists five RTP versions: 84.25%, 87.25%, 91.25%, 94.25% and 96.25%. Each version keeps the name and artwork, with the maths tuned to a different long-run return. The casino picks which one it runs, within any minimum its regulator sets. Studios say they offer several because markets differ: minimums vary between regulators, and casinos weigh taxes, margins and commercial terms. A higher setting does not guarantee a profit, and a short session can finish up or down either way. This demo uses virtual credits: nothing is deposited, withdrawn or paid out, so the setting has no financial effect.

How to play the free demo
- Every win in the Gigantoonz demo is a group of matching symbols connected on the 8x8 grid, with no paylines to follow.
- Watch for Mega Symbols, which can be anything from 2x2 to 7x7 and leave Quantum Wilds behind when they are removed.
- Track the Quantumeter: its modifiers unlock at 25, 50, 75 and 100 charges, with Gigantoon Mega Wilds as the fully charged reward.
Why try the Gigantoonz demo
Watching the Quantumeter fill with winning symbols shows Disintegration, Metamorphosis and Radiation each acting on the grid before a full meter brings Gigantoon Mega Wilds. Mega Symbols keep working after they pay, since each one removed after a win leaves Quantum Wilds behind for the follow-up cascades.
