As always, Peter & Sons has taken a lot of time and care in creating the visuals for this slot. The game takes you to a mystical clearing in some woods where a rather unhinged-looking man is draped in a catfish cape and a fish belt. It’s exactly the kind of quirky world we have come to expect from the developer.
The symbols include card suits and several water-dwelling creatures, each designed with an impressive blend of realism and cartoon. The animals include a frog, a pufferfish, and an octopus. All symbols can appear in larger forms up to 6x6 in size, known as Gigablox. A Gigablox is guaranteed on every spin.

Let’s see what is bubbling under the surface with the following WaterBlox Gigablox features.
At least three Scatter symbols are required to trigger the bonus feature. If you land two, there is a chance that a hook may pull up one of the reels to reveal another Scatter. If the two landed Scatters can move down one position without leaving the reels, then the reels with Scatters might shift down one while the other reels are respun.
On any random spin, up to three symbols can be transformed into Wilds. They will payout any wins created by the change before launching a respin. During the spin, some Wilds will roam the reels and land in a different position while others stay in place. The size of the transformed symbols determines the number of Wilds that will roam. If a Wild lands on a Gigablox, it will convert that entire symbol into a Wild.
Landing five or more Scatters triggers this feature, where the number of spins awarded is equal to the number of triggering Scatters. After every spin, the Wild Respin feature is triggered. The Wilds are collected on the scales to the bottom left of the reels. You will receive a multiplier and additional Free Spins for collecting different numbers of Wilds.
After 20, you get a 2x multiplier and two more spins. At 25, the multiplier becomes 3x and you get two more spins, at 30 the multiplier is 5x with two additional spins, and if you collect 50 Wilds during Free Spins, you get a 10x multiplier and two more Free Spins. A respin also occurs when these targets are reached.

It is difficult not to be won over by WaterBlox Gigablox’s design. Like all Peter & Sons’ slots, the game is undeniably imaginative and detailed. These rich visual elements are combined with great gameplay and a 10,000x maximum win. The Gigablox feature is always fun to play with, and the Wild-based bonuses create some great winning potential. Overall, this is a really solid offering.
