Powered by Yggdrasil, Monster Blox is another wicked slot from Peter & Sons. A first in their Gigablox series, this monster of a game displays a full suite of intriguing bonus features alongside entertaining graphics. The frightful name suggests some freaky gameplay, but the fantastical theme here is actually quite pleasant, with beasts appearing in regular and Gigablox formations. Still, don’t let those monsters fool you – it’s a volatile 6-reel and 4-row slot with 40 paylines and only the bravest of players will be offered the biggest bounty.

Monster Blox Bonus Features

For such a simple slot, there’s a good amount of bonus features happening within the grid of Monster Blox. First off, you have the signature Gigablox feature providing you with oversized symbols that function like 2×2 up to mega 6×6 formations. Then, there’s Monster Re-spins – these can increase your playing field significantly. Wild Bounty is an added symbol transformation extra with a Monster free spins bonus game rounding everything up into one rather monstrous adventure.


Appearing as monster hunters, wilds can help complete a winning combination, but they don’t emerge until the respin or the Wild Bounty features trigger. Once in view, they substitute for all paying symbols except scatters.


Scatters are slot features that resemble animated books and activate the free spins bonus round when 5 or more symbols of a kind pop up anywhere in view. As well as regular symbols, scatters can also land as Gigablox.

Wild Bounty Feature

Hovering to the right side of your reels, the monster hunter can burst into action at any point, so watch him closely. When he’s active, he can transform any symbols, including Gigablox, into wilds during the main game and the free spins round.

Monster Re-Spins

Each winning spin during the base game awards a respin resulting in a bigger grid. Here, you’ll see paylines increase with the regular grid growing one row taller for each win, up to a 6×8 panel with 100 paylines.The Wild Bounty feature triggers at random during the respins too.

Free Spins

When the free spins round triggers, you’ll get to play on the fully expanded 6×8 grid with as many free spins as it took you to unlock this bonus feature.

Each scatter landed awards an extra 1 free spin as well as triggers the increasing multiplier feature, providing you collect enough scatters needed to fill the meter. With 15+ scatters, you can earn a multiplier of up to 10x. Also, the Wild Bounty feature triggers more often during this round and will occur on non-winning spins to guarantee a win.

Monster Blox Jackpot

Monster Blox is anything but a jackpot slot and yet it can still offer you some jackpot-worthy payouts of up to 7,900x your stake.

RTP and Volatility

Due to high volatility, it will take you some time to tame those cash-paying critters, so be patient. At the same time, the RTP of 96.10% is set in stone and can’t be altered by the casinos, which is great news for you.
