Monsters vs Gigablox Features

For Monsters vs Gigablox, Yggdrasil has gone for a basic feature list. The slot’s base game is generally quiet, with Gigablox being the only feature that injects some life. Free spins are the game’s most exciting mode, especially when combined with Gigablox for even more eventful spins. The use of Yggdrasil’s signature mechanic is great, but unfortunately, it’s supported by a limited set of features. This makes for a less engaging experience, but the more subdued pace might still be appealing to some.

Wild Symbols

Wild symbols in Monsters vs Gigablox are represented by a Golden Crown. These tokens step in for any missing pay symbols that could form part of a winning combination. Unfortunately, that’s where their use ends. The symbols carry no value of their own and as such only have significance when forming part of another winning combination.


Yggdrasil’s signature mechanic, Gigablox symbols pop up as larger-sized tiles that appear at random on merged reels to form symbols in blocks of 2×2, 3×3, 4×4, 5×5 and 6×6. Whenever they form part of a winning combination the Gigablox symbols are broken down into single 1×1 symbols for their payout to be calculated accordingly.

When triggered in the base game, Gigablox symbols can feature pay symbols, scatters, and wilds. This makes it the most interesting feature during normal spins, allowing for some great wins to come along. During free spins, the feature still boosts players’ chances, but its effectiveness is reduced. In the bonus mode, they only show monster symbols, the highest pay symbols in the slot.

Buy Feature

Players can skip the scatter symbol grind and just straight into free spins thanks to the buy feature. This comes at the cost of 75x the selected bet with between 9 – 30 free spins, as well as an RTP increase to 96.27%.

Monsters vs Gigablox Free Spins and Bonus

Accessing the Monsters vs Gigablox bonus mode takes no less than 5 scatter symbols. Players can score between 9 to 40 free spins, depending on the number of scatter symbols that trigger the bonus rounds. Upon activation, the most present monster on the reels becomes the Rampaging Monster for the duration of the bonus. The Rampaging Monster turns wild and is presented with a golden frame, giving any wins involving the symbol twice their original value. The symbols are also larger here in free spins than they are during the base game.

Monsters vs Gigablox Theme and Symbols

Monsters vs Gigablox is a visual spectacle. The studio has taken its time to develop an engaging theme that is fantastically fleshed out in visual design, audio, and animation. It’s a joy to watch the reels unfold, as the carnage ensues across the city’s reels. Unfortunately, the fantastic visual presentation is let down by a lacklustre set of features that don’t quite deliver the same punch.

Monsters vs Gigablox RTP & Volatility

Monsters vs Gigablox is a highly volatile game which means that wins will be very infrequent yet potentially substantial. The slot’s return to player rate is pretty average, sitting at 96.10%. This can of course be bumped up to 96.27% by activating the Bonus Buy feature. The slot itself is quite mild, offering a maximum win potential of 3,116x. The bonus buy feature may not be available to players in certain countries.

How to Play Monsters vs Gigablox

Monsters vs Gigablox is played on 6 reels and 6 rows, with 50 fixed paylines to win from. Players are treated to a game information and a pay table before having to set their preferred bet between £0.50 and £80, a pretty decent range. Once all that has been set, simply hit the spin button to play. An autoplay function with its very own gameplay parameters has also been included – it makes longer play sessions a much more straightforward affair but always stick to a strict budget and gamble responsibly.

Slotsia’s Review

With Monsters vs Gigablox, Yggdrasil manages to deliver a stunning visual spectacle which features its very own Gigablox. But the slot’s lacklustre features don’t match the engaging visuals, mean that this is an underwhelming effort from the famed provider.
