Gigantoonz Slot RTP, Details & Wager Limits
The Gigantooz slot comes with an 8×8 grid, with winning combinations formed by landing 6 or more matching symbols in clusters. This simply means that they need to be next to each other. The larger the cluster, the larger the potential return at the end of that spin.
Stakes range from 20p up to £100 per spin. To adjust your total bet, simply choose one of the values below the reels before you spin. It’s worth remembering here that although Autospins may be available in many territories, it’s not an option for UK players.
The Gigantoonz RTP is 96.25%, which is slightly above average for a Play ‘n GO slot.
The maximum win is 4,000 x your stake, which isn’t too bad but is a fair bit lower than some of the better games on the market. With variance at a maximum of 10 out of 10, bigger wins will land a lot less often than smaller ones.
Theme – Audio & Design Features – bigger and better
Set in a universe far, far away and with an alien theme, this Gigantoonz slot game is very similar to the Reactoonz 2 slot and the original before that.
The design is very bright and colourful, with each symbol having its own distinct colour. Much like the previous titles in the series, there are small aliens and higher-paying ones. The most lucrative symbol is the red alien, paying from 5 to 1,250x your bet for between 6 and 30+ in combination.
There’s also the familiar Gargantoon, which is the game’s wild. It replaces all symbols and can shake things up in the bonus features for potentially big wins.
| Symbol | Payouts/Info |
|---|---|
 Yellow Alien | 6 to 30+ = 0.1 to 5 x stake |
 Green Alien | 6 to 30+ = 0.1 to 5 x stake |
 Brown Alien | 6 to 30+ = 0.2 to 10 x stake |
 Purple Alien | 6 to 30+ = 0.2 to 10 x stake |
 Turquoise Alien | 6 to 30+ = 0.3 to 20 x stake |
 Blue Alien | 6 to 30+ = 0.3 to 50 x stake |
 Orange Alien | 6 to 30+ = 0.4 to 100 x stake |
 Harlequin Alien | 6 to 30+ = 0.4 to 200 x stake |
 Magenta Alien | 6 to 30+ = 0.5 to 400 x stake |
 Red Alien | 6 to 30+ = 1 to 1,250 x stake |
 Gargantoonz | Appears as wild and substitutes for all symbols |
 Wild | Replaces all symbols |
Gigantoonz Mobile
You can enjoy the Gigantoonz mobile slot on all devices including smartphones and tablets as well as desktops. The 8×8 grid looks great on smaller screens, and the HD graphics and responsive gameplay make for a nice experience on mobile.
Gigantoonz Bonus Features
The Gigantoonz slot comes with 4 main bonus features. From mega symbols to quantum wilds, there’s plenty of action to be had here. Let’s explain each one in more depth to help you fully understand how the game works.
Cascading feature
When you land a winning combination of 6 or more matching symbols, this triggers the cascading feature. All winning symbols are removed from the grid and new ones fall into place to replace them. This continues until no new winners are formed.
Mega Symbols
These may appear in 2×2, 3×3, 4×4, 5×5, 6×6 or 7×7 sizes. Each one has a random value of up to 13. When a winner lands, a mega symbol counts as a single symbol, but the payout of the winning cluster is determined but its cluster value.
What’s also great about these is that each winning mega symbol leaves a wild on the grid, which could result in a nice upcoming win.
Quantumeter feature
5-10 Quantum Wilds may appear randomly on the grid on any non-winning round. Gangantoon Wilds can also appear, but through the Quantumeter only.
One charge is added to the Quantumeter with each winning symbol, but Mega Symbols add their full cluster value. The Quantumeter holds up to 100 charges and there are 4 charge levels, as outlined below.
| Level 1 | 25 Charges | Triggers Disintegration |
| Level 2 | 50 Charges | Triggers Metamorphosis |
| Level 3 | 75 Charges | Triggers Radiation |
| Level 4 | 100 Charges | Triggers Gargantoonz |
But what do these all mean? Let’s break it down for you:
- Disintegration – Removes 4 randomly selected symbols and all instances of them on the grid.
- Metamorphosis – Transforms all of 1 symbol into another symbol, including mega symbols.
- Radiation – Randomly adds 1-4 mega symbols and 2-5 quantum wilds to the grid.
- Gargantoonz – This comes in 2 parts. First, all mega symbols are turned into mega Gargantoonz, with 3+ mega Gargantoonz appearing as well as 2-4 1×1 symbols. Secondly, all mega Gargantoonz are broken down into 1×1 symbols.
The features might not be as in-depth or as unique as some other slots, but there’s enough going on here to keep players interested.
Gigantoonz Review Summary – 8×8 fun
The Gigantoonz slot game is a good one, but if you’ve played Reactoonz or even the Dr Toonz slot, are you getting much more with this release? Apart from a bigger grid, arguably not. The max win is lower than both Reactoonz releases. Dr Toonz’ max win is much higher at 22,000 x your stake if you want something with better potential for large wins.
Why not give our free demo a try first? It will help you get to grips with the game and its features, and you don’t have to use any of your own funds either. Yes, this game is bigger than the previous releases, but is it better? It lacks in some areas but makes up for it in others.
If you’re a fan of the theme and the cluster pays mechanic, there are plenty of other slots to consider that are worth your time. BTG’s Diamond Fruits Megaclusters is one example, so too is Cyberslot Megaclusters, which comes with potential max wins of 23,960x.
We hope we’ve been able to help you with our Gigantoonz review. Good luck with any future bets.
Gigantoonz FAQs
The Gigantoonz RTP is 96.25%, which is pretty much average for a Play ‘n GO slot. But with the variance here extremely high at 10/10, don’t expect large wins too often.
The max win is 4,000 x your total bet, which is reasonable but by no means close to the highest on the market. Your best chance of landing this is during one of the bonus features.
Gargantoons make an appearance during $1 as wilds and substitute for all symbols. Each winning symbol charges the Quantumeter, and you have the chance to build up your levels for potentially bigger wins. We explain it all in more depth in our review.
Yes. $1 at Online-Slot.co.uk. It’s a good chance to try the slot before deciding to use any of your own funds.
