Water Blox Gigablox Slot RTP, Details & Wager Limits

Reels/Paylines: 6 reels + 50 paylines

Stakes Range: 20p to £50 per spin

Max Win: 7,500 x stake per spin

RTP: 96.07%

The Water Blox Gigablox slot is played with 6 reels, 6 rows and 50 paylines. It looks like a grid slot but it’s not. Anyway, you need to land 3, 4, 5 or 6 matching symbols from left to right beginning from the first reel.

Playable from 20p to £50 a spin, click on the ‘bet’ button below the reels. This will bring up all 17 available bet/stake options. Next to that is the Lightning Bolt icon which enables Turbo Mode for faster spins. In the same area there is the Autoplay function where you can choose infinite autospins. Both latter options are not available in the UK though.

The Water Blox Gigablox RTP is 96.07%. This is marginally above the 96% online slots average though. The volatility is high with a win landing every 4.76 spins on average as the hit frequency rate is 21.01%.

When it comes to payouts, the maximum win per spin is 7,500 x your total stake. The bigger wins will come in the free spins with a multiplier up to 10x can come into play. It will, however, take 372 spins on average to trigger the Free Spins feature.

Theme – join the shaman in catching giant sea creatures

Theme: Spiritual

High Value Symbol: Red Octopus

Compatibility: Mobile, Tablet, Desktop


With a spiritual theme, the Water Blox Gigablox slot is set where the forests of Walarya and the ocean meet, with huge sea creatures travelling up the fjords. There’s an old shaman who stands at the magic pond ready to catch these creatures.

Using Peter & Sons’ usual visual style, the game looks more than an animated movie than a video slot. It’s a lot more of a cartoon than the Blue Planet documentary by David Attenborough.

Set at the magic pond, the shaman is perched to the side of the reels. Using the Gigablox mechanic from Yggdrasil Gaming, symbols can appear as gigantic blocks up to 6×6 in size.

Symbols include spade, club, heart and diamond blocks as well as frogs, puffer fish, purple fish and octopi. The red octopus is the best paying symbol giving you 1, 2, 2.5 or 10 x stake for 3, 4, 5 or 6 in combination.

The angry gold fish is the wild symbol and can appear on all 6 reels. Substituting for all symbols mentioned, 6 wilds on a payline will award a 10 x bet payout (like the red octopus). The free spins bottle is the scatter with 5 or more triggering the main bonus feature.

Water Blox Gigablox Mobile


Being so beautifully designed, Peter & Sons use HTML5 technology to create their slot games. Water Blox Gigablox is therefore available to play on mobile, laptop, PC and tablet devices. Despite the graphics being amazing on iOS and Android mobile devices in particular, a larger screen is recommended to get the full visual experience.

Water Blox Gigablox Bonus Features

The Water Blox Gigablox slot comes with 3 bonus features. There are symbols that can random change into wilds with a free re-spin to follow and the potential for big block wilds. This occurs on each free spin during the Monster Free Spins feature where collecting wilds adds more free spins and increases the multiplier up to 10x.

Wild Re-Spin feature

Randomly triggered in the base game, there Wild Re-Spin feature can come into play. Between 1 and 3 symbols will change into wilds with a re-spin to follow. If a win is awarded, wilds then roam and change position.

The size of the symbols that change into wilds will define the number of roaming wilds. A 1×1 wild will give you 1 roaming wild with a 6×6 wild gives you 6 roaming wilds. If a roaming wild lands on a big block, the entire block transforms into a wild.

Monster Free Spins feature


The Monster Free Spins feature is activated when landing 5 or more free spins bottle scatters on any base game spin simultaneously. The number of free spins you’re award is equal to the number of scatters that triggered the feature. Once in, each scatter landing will award 1 extra free spin.

The Wild Re-Spin feature is in play during each free spin meaning 1 to 3 symbols are transformed into wilds. Each wild you land will add points to the Wild Meter. Wilds from the re-spins are not collected though. Anyway, when the meter is full, the multiplier increases and additional free spins are won:

Wilds Collected Multiplier Extra Free Spins
20 2x +2 free spins
45 (in total) 3x +2 free spins
75 (in total)n 5x +2 free spins
15 (in total) 10x +2 free spins

Buy Free Spins feature

For non-UK slots players, there’s a Buy Free Spins feature. There are 3 options to enter the free spins. You can pay 58 x your total stake for 10 free spins or 580 x stake for 20 free spins. You can get a random number of free spins for 140 x your total stake.

RTP (96.07%)

Max Win (7,500 x)


The Water Blox Gigablox slot has to be one of the best designed games I’ve ever come across. Peter & Sons seem to be raising the bar even higher on their extremely high standards visually. The graphics could easily be used in a children’s TV series or film. They are that good.

When it comes to the gameplay, the Wild Re-Spin feature triggers frequently resulting in roaming wilds. It can lead to decent payouts if the wild transform the entire blocks wild. Obviously the bigger payouts will come in the Monster Free Spins feature as the wild re-spins are in play on every free spin.

The key is to collect as many wilds as possible. This will give you extra free spins but also increase the multiplier up to 10x. You need to play with a decent number of free spins to achieve the multiplier increase though which pushes you to buy your way into the feature (not an option for UK players).

That said, the potential 10x multiplier is what can lead to 7,500 x stake max wins on each free spin. In summary, it’s beautifully designed, offers a potentially lucrative free spins game and feels quite different from other Gigablox slots. Visually, it’s better than Yggdrasil Gaming’s Golden Fish Tank 2 Gigablox.

If you’re a fan of Gigablox slots, the best option is still 4ThePlayer’s 90k Yeti Gigablox. With 46,656 ways to win, there are 3 random base game features, free spins and 90,000 x stake max wins per spin.

  • Amazing graphics + animations
  • 7,500 x stake max wins
  • Entertaining Monster Free Spins feature
  • Difficult to play with 10x multiplier in free spins
