Monsters vs Gigablox

Reelplay frames Monsters vs Gigablox around a city-under-siege scenario reminiscent of giant-monster disaster films, viewed from above as a burning skyline surrounds the play area. Six premium monster symbols, led by a towering ape-like creature, make up the higher end of the pay table, while nine through ace card ranks fill the lower tier and a golden crown wild substitutes for every paying symbol.

The grid runs 6 reels by 6 rows with 50 fixed paylines, and wins land whenever three or more matching symbols connect from the leftmost reel. Layered onto that grid is the Gigablox mechanic that gives Monsters vs Gigablox its name: oversized symbol blocks, sized from 2x2 up to 6x6, can appear on merged reel positions and break down into standard single-tile symbols once a win is evaluated. In the base game, Gigablox blocks can be built from any paying symbol, scatter or wild; during free spins, only the monster picture symbols form them.

The bonus opens once five or more scatter symbols land, worth 4 spins on its own with one extra spin added per further scatter, up to a ceiling of 40. Whichever monster symbol appears most often at the moment the bonus starts becomes a golden Rampaging Monster for the round, acting as a wild and doubling the value of any win it takes part in. A Buy Bonus option is available for 75 times the stake, guaranteeing between 9 and 30 free spins on entry.

Reelplay rates Monsters vs Gigablox as high volatility, backed by a hit frequency of 38.38% and a headline RTP of 96.1%, rising slightly to 96.27% when the bonus is purchased. Bets go as low as 0.50 and as high as 80, with a maximum win of 3,116 times the stake.
