Page updated July 2026
Dragonblox sends players after a sleeping dragon's treasure hoard, built on Peter & Sons' partnership with Yggdrasil's Gigablox mechanic and following on from the studio's earlier Monster Blox release.
The setting is a dungeon-like lair where a red dragon slumbers atop a mountain of gold, its coiled body framing the 6-reel play area, each reel holding six symbols. It's a well-executed if slightly familiar fantasy scene — less imaginative than Monster Blox in concept, but delivered with a distinct enough style to stand on its own. Wins pay across 50 paylines from matching symbols, drawn from a mix of card-suit lower pays and a cast including archers, knights, a wizard, a ring-bearing hobbit-like figure, and a warrior.
The Gigablox mechanic is the real draw: individual reel symbols can merge into blocks as large as 6x6, with each block counted as the equivalent number of standard symbols when tallying up wins. A Golden Bet option increases the stake by 1.5x in exchange for a higher chance of Gigablox symbols appearing and bonus rounds triggering, alongside a Monster Jackpot feature built around lock 'n' blox mechanics and free spins.
Dragonblox Gigablox carries a 95.9% RTP, a reasonable if unremarkable figure that sits close to the market average. In practice, that means the game is designed to return around £95.90 for every £100 wagered over a long run — fair, if not exceptional, compared with some of the higher-RTP dragon slots in the catalogue.
Volatility is rated High, which fits neatly with the Gigablox mechanic itself — the potential for reels to merge into huge blocks creates the kind of spiky, unpredictable win structure typical of High-volatility slots, with quieter spells punctuated by a Gigablox symbol suddenly filling a large chunk of the grid.
Stakes run from 50p up to £/€50 per spin, with the Golden Bet option pushing the effective stake higher still in exchange for better odds at the bigger mechanics. No maximum win figure has been confirmed for Dragonblox Gigablox.
Dragonblox Gigablox brings a genuinely satisfying big-symbol mechanic to a well-worn dragon-treasure theme, and while its 95.9% RTP is middling rather than standout, the High-volatility Gigablox swings and Monster Jackpot feature give it real potential.
