Monster Blox by Peter & Sons is a high-volatility slot released in 2023 with a 6x4 base layout, 25 paylines, and a default RTP of 96.09%. The game uses a changing grid structure, where winning spins can trigger Monster Respin and add rows to the board, expanding the playfield up to 6x8 with more paylines active.
The slot features Gigablox symbols, which can appear in large block formations, alongside Wild Bounty symbols that can turn other symbols into Wilds during base play and respins. Free spins begin with 5 or more Scatters on the expanded grid, with extra spins awarded for additional Scatters and a Monster Multiplier that rises as the bonus round develops.
Players can use the demo version to play for free and practice before playing for real money. Monster Blox also includes a feature buy option, a maximum payout of 7,500x stake, and a bet range from 0.2 to 100.
