The Gigablox Mechanic
Gigablox is a Yggdrasil mechanic where reel positions combine into a single large symbol. Base-game blocks can be 2x2, 3x3, or 4x4. In free spins, they expand up to a 6x6 size.
A big block breaks into standard symbols for win calculation. A 3x3 fish block equals nine fish symbols, letting one landing fill multiple paylines instantly.

- Base game block sizes: 2x2, 3x3, and 4x4
- Free spins can feature blocks up to 6x6 on Expanded Reels
- Payout rule: a block counts as all symbols it contains
- Scatter rule: a giant Free Spins block counts as multiple scatters
Treasure Chest Feature
This sequel adds the Treasure Chest. Landing it in the base game makes bubbles burst to show either cash or a free spins award.
- Cash prizes range from 2x to 500x your stake
- Free spins awards range from 5 to 16 spins, including feature picks
- During free spins, chests can award extra prizes and additional spins
