Gigantoonz

Updated Written and checked by the Casinos-Online editorial team

Gigantoonz is the sequel to Reactoonz the series from Play n go. A very popular set of slot machines. In Gigantoonz, you will keep coming across the characters from Reactoonz, which is what the game is about. Mega symbols will make a much bigger impact in this game, and the figure Garganton stars.

Sore Gigantoonz

Like its predecessors, Gigantoonz is a grid-based slot where you win in clusters. There are no paylines in the game. Instead, you win by getting matching symbols in a cluster. You must at least get a cluster of six identical symbols in order to win. The playing field is large and consists of a grid of 8×8 squares. Each square is initially covered by a Reactoonz figure, but as the game progresses, mega symbols will appear that cover more than one square.

The symbols come down almost like an avalanche, and there are so many events that happen on the screen simultaneously. It's necessary to maintain a level of engagement and watch the playing field attentively in order not to overlook anything. And believe me, you need to watch the Quantumeter, which we will break down in more detail later on in this review. You win, it gets loaded, and it gets loaded every time something else happens on the screen that would otherwise be a common feature in a different slot. You see, the different slot.

Bets & winnings

Machine work is like anything else: you decide how much to put in. Gigantoonz, however, doesn’t require you to pick a coin size, which makes picking a bet level much easier. At the bottom of the playing field, you see the bet levels. You can choose very small bets or fairly sizable ones, but the minimum per spin is an amount set by the casino and the maximum is an amount set by the casino. Click on the bet you want to play with, and scroll through the levels with the Plus and Minus sign.

The game features a maximum win of 4000 times your bet. As stated in the introduction, there are no conventional winning ways, but Gigantoonz functions as a cluster slot. This means that you win by matching symbols that are in a cluster. To achieve a win, you need a minimum of six identical symbols clustered together. On top of that, you can also have mega symbols as part of the cluster, which are symbols that take up multiple slots and increase your odds at winning.

RTP Gigantoonz

The game has an RTP (return to player) which means a theoretical return of 94.25 %. The game also has a high volatility. For you as a player, this means that the winnings come relatively rarely, but once they come, they are quite large.

Functions

Gigantoonz has many components to monitor, and this is what makes the game so enjoyable. At its core, though, it is the interplay between these components that creates the Gigantoonz experience. For a newcomer to the game, though, it can at first seem an overwhelming chaotic interaction, an out-of-control jam session of game features. Easing into it by playing for low stakes can help with getting the hang of it.

Mega symbols and wilds

The mega symbols are what we want to kick this feature section off “speaking” about. During each spin, any symbol can appear as a mega symbol capable of reaching from 2×2 in size to 7×7. They can thus almost cover the entire playing field. Even though they.

When a mega symbol has been used in a winning cluster, you will receive a Quantum wild symbol from it. It drops onto the playing field if the opportunity exists, if the opportunity does not exist, it becomes a regular 1×1 symbol. You can also opt to get between five and 19 Quantum wild symbols on any spin that results in no win. They can end up anywhere on the playing field, and will help you get a win.

Quantum meters

The next function, which is perhaps also the most important to keep track of, is the Quantumeter. The meter is located on the right side of the playing field and is recharged every time you win. You can recharge it up to 100, but you are also awarded bonuses at 25, 50, and 75.

  • Charge 25—Disintegration is invoked. Four random symbols vanish and are substituted.
  • Morpheus: 50. All squares consisting of a randomly selected symbol disappear and replace.
  • Charge 75-Radiation is initiated. 1-4 mega symbols and 2-5 Quantum wilds will be randomly set on the playing field.

Charging the Quantum Meter to 100 charge on one spin triggers the Gargantoon wild, which takes place in two stages. 1. All mega symbols morph into gargantoon mega symbols. You'll also get 2-4 regular-sized gargatoons for good measure. 2. All gargantoon mega symbols transform into 1×1 symbols, which win more often than not. As you can imagine, these clusters can get really big and pay off well!

Symbols

Gigantoonz has a ton of symbols since the playing field is so large. One rule to watch for is that the one-eyed figures are the somewhat lower paying symbols, while their two-eyed counterparts will pay you more.

If you play at the minimum bet, the one-eyed symbols will award you anywhere the minimum the casino sets. Meanwhile, the two-eyed symbols can give you payouts the minimum the casino sets all the way up to the casino's cap. To win with either type of symbol, you have to get at least a cluster of 6 identical symbols. For the highest cluster win possible, you need to get 30 of the same kind of symbol (or more).

The wild symbol in Quantum is unmistakably a space-inspired spinning orb. The wild symbol in Gargantoons is more down to earth—except for its three eyes.

Summary

Gigantoonz is a slot machine that is fun and fast-paced, where a lot is happening most of the time. It is the sequel to the very popular Reactoonz slot machines. Once again, we get to meet the characters from the Reactoonz universe, with Gargantoon taking on a leading role this time around. Unlike its predecessor, Gigantoonz comes with mega symbols that give bigger wins, and a meter that recharges with every win and can trigger bonus features.

For you, as a novice in the world of slots, this one could feel advanced, and it might take you a few rounds to understand the features fully. Still, this series of slots created by Play'N GO has grown to be quite popular, and we have no reason to believe that the sequel, Gigantoonz, wouldn't be just as beloved!

Our review Gigatoonz

We have, of course, tested Gigantoonz to provide you with the best information about the game. If you have played the Reactoonz games before, you will most likely also enjoy Gigantoonz. It is a game with a lot happening, and it is certainly not a game where you can sit and watch the news without missing something. We took a decent amount of time to understand all the features that are in the game, which is actually quite good—it's always better to start with lower stakes in a new game anyway.

The available features are a blast, and the Quantumeter is clearly a cut above what you find in lots of other slots. If you want a high-octane experience, Gigantoonz is a veritable thrill ride.
