Game Studio Play’n GO has created a few iconic hits over the years. One of them is Reactoonz.
Understandably, PnG wants to profit from the popularity of its hit slots, and one way to do that (and extend the brand’s lifetime) is to release sequels.
As with movies, this is easier said than done, and PnG’s previous attempts with Reactoonz 2 and Dr. Toonz did not fulfil their fans’ expectations, so let’s try this again with the release of Gigantoonz.
In Gigantoonz, Play’n GO has returned to the basic elements that made the original slot such a mega hit while adding something new to enhance the experience.
However, as always with PnG slots, they are released with various RTP versions, so choose your online casino wisely to play the best-paying option.

Gigantoonz is available in five different Return To Player (RTP) versions.
These average a payout of 84.25%, 87.25%, 91.25%, 94.25%, or 96.25%.
The higher the RTP, the more likely you are to get more spins out of your playing balance.
Why settle on playing with lower odds when not needed, right?
The differences between the RTP versions can be pretty significant, as shown in the example below.
The following table shows how many spins you will theoretically get to play before your money runs out, based on a starting balance of £100 and a stake of £1 per spin.
| Gigantoonz RTP | Number of spins |
| 96.25% | 2,640 spins |
| 94.25% | 1,721 spins |
| 91.25% | 1,131 spins |
| 87.25% | 776 spins |
| 84.25% | 628 spins |
Is there any reason to accept a lower-paying version of Gigantoonz when better alternatives are available?
The bad news is that most online casinos prefer to offer one of the lower-paying versions to their players, as the casinos want to increase their profit margins.
The good news is that the CasinoWizard has scanned hundreds of the most well-known and trusted UK casinos to find the ones that let you play Gigantoonz with the highest payout slot setting we could find.
All you need to do is choose one of those casinos listed on the RTP comparison table above and start playing with the best odds.
Playing with a higher Return to Player increases your chances of winning and playing time.

Gigantoonz is a highly volatile slot played on an 8×8 grid using the Cluster Pays mechanic, where at least 6 matching symbols in a cluster create a win.
The winning clusters are removed and replaced by new symbols until no more wins happen.
Mega symbols of sizes 2×2, 3×3, 4×4, 5×5, 6×6, or 7×7 can appear in Gigantoonz and carry a randomized cluster value up to 13.
What else? 5 to 10 Quantum Wilds can randomly appear on the grid on any random non-winning spin, helping you achieve wins.
However, the main aim is to fill the Quantumeter with up to 100 charges, as this triggers the Gargantoonz modifier.

Gigantoonz can deliver wins of up to 4,000x your bet size per spin.
This is very similar to the 4,750x max win offered on Reactoonz.
The max win probability on Gigantoonz is about 1 in 4,8 million, which is excellent.
We have seen Play’n GO follow this path with other slots, like sequels to the famous Book of Dead, but how can we blame them for this?
Naturally, both players and the game studio would like to see an extension of something entertaining, but the execution of the product (or, in this case, the slot) isn’t always up to standard.
Play’n GO still has some work to do to hit the heights of Reactoonz, but Gigantoonz is at least an improvement compared to previous sequels to this mega-hit.
However, fans of the concept and grid slot will certainly enjoy Gigantoonz.
Play on the best RTP version for the best odds.
