Water Blox Gigablox: Slot Overview

Created in collaboration with partner studio Yggdrasil, Water Blox is Peter & Sons’ second title to feature the ever-growing Gigablox feature. The first, Monster Blox, looked so unmistakably Peter & Sons that it was easy to overlook you were even playing a Gigablox-driven slot. Water Blox follows the same path and, alongside Gigablox, brings roaming wild respins and a rising free spins multiplier, all set in a realm where Walarya’s forests blend into bright blue fjord waters.

With a Peter & Sons release, “crafted” feels especially fitting, as the studio’s visual identity is truly one of a kind. Water Blox showcases that style perfectly, dropping players into a strange (in the best sense) almost enchanted world that leans into aquatic life. A lily-pad-filled pond sits at the bottom of the screen with a leaping fish, while more water-dwelling creatures populate the 6×6, 50-payline grid. Mystics and magic are classic Peter & Sons motifs, and here a mystical figure stands beside the game panel. From time to time, he slips into a fish suit—like he’s channeling the spirit of our underwater friends—to fire modifiers onto the reels. A little magic is expected in a Peter & Sons review, and Water Blox delivers.

The numbers hold up as well, with Water Blox running a highly volatile math model and a comfortably average RTP of 96%. Wins are expected on 21.01% of spins—around 1 in 5—when at least three matching symbols land from the left on a payline. For staking, the game offers bets from 20 p/c to $/€50 per spin.

Water Blox includes 8 standard paying symbols. The four lower-value icons are stylised spades, clubs, hearts, and diamonds, paying 0.8x the bet for six on a line. Above them are four higher-paying animal symbols—frogs, pufferfish, purple fish, and a standout octopus—returning 2 to 10 times the stake for six of a kind. The wild is an angry gold fish that can land on any reel and substitute for all paying symbols. A winning line of six wilds pays the same as the octopus at 10x the bet.

Water Blox Gigablox: Slot Features

In Water Blox, Yggdrasil’s Gigablox mechanic appears alongside roaming wilds, respins, Monster Free Spins, and a buy bonus.

Gigablox

Gigablox are oversized symbols ranging from 2×2 up to 6×6. They may land on any reel, and for win calculation they are broken down into individual 1×1 tiles.

Wild Respins

In the base game, 1-3 symbols are changed into wild symbols at random. Once any wins are paid, a respin begins where the wilds move to a random position. How many roaming wilds appear depends on the size of the symbols transformed—1×1, 2×2, 3×3, 4×4, 5×5, or 6×6 blocks generate 1, 2, 3, 4, 5, or 6 wilds, respectively. During the respin, if a roaming wild lands on a large block, it converts the whole thing into a wild.

Monster Free Spins

Hitting at least 5 scatter symbols in the base game activates free spins. The amount awarded is equal to the number of scatters in view, and every scatter that lands during the bonus adds one more free spin. The Wild Respin feature remains active on every free spin, meaning 1-3 random symbols are turned into wilds as outlined above. On top of that, each wild symbol is collected and adds a point to a meter. After collecting 20, 45, 75, or 125 wilds, the win multiplier increases to x2, x3, x5, then x10. Also, at each collection threshold, +2 free spins are granted. Note that wilds from respins are not collected.

Buy Bonus

Where offered, players can choose from three bonus buy options. Spend 58x the bet for 5 free spins, 580x for 20 free spins, or 140x the bet for a random number of free spins.

Water Blox Gigablox: Slot Verdict

Monster Blox set a high bar visually, and Water Blox holds its own. It’s packed with the kind of fine detail Peter & Sons are known for, and it feels like they’re only getting sharper at it. The studio excels at cramming in layers of quality touches to make a slot feel distinctive, and Water Blox is a strong example. Just look at that octopus, or the way the fish-belted shaman tugs on his fish-skin costume. The setting is delightfully odd in all the right ways, and it’s another P&S title that’s easy to get lost in. If you’ve ever read Where the Wild Things Are, Water Blox carries a similar vibe.

With the presentation sorted, does it play well? Largely, yes. Using Gigablox does mean the game is somewhat boxed in by the mechanic’s core rules. Even so, Gigablox can be exciting on its own, and pairing it with roaming wilds is a smart twist. It created some great base-game moments when larger Gigablox tiles were turned wild, and even better ones during the bonus.

The odds of landing bigger payouts improved noticeably when you started with more free spins. That’s true in general, but it stood out in Water Blox because building up enough collected wilds to unlock stronger multipliers can take time. Beginning with only a few free spins often made that goal much harder. As for upside, the game promotes wins of over 10,000x the bet, so strong results are on the table when things line up.

In the end, your overall enjoyment of Water Blox will depend heavily on how you feel about the Gigablox feature. Still, it’s a good-looking, unmistakably P&S entry, and the roaming wild respins help make it a very playable addition to the Gigablox slot lineup.
