How to play

Four colours, 22 polyiamond blocks each, one 486-space hexagonal grid. Chain your blocks outward without ever sharing an edge with yourself.

Setup

Play runs Blue → Yellow → Red → Green. Each colour's first block must cover its marked starting node in the ring around the centre of the grid.

Your turn

  1. Pick a block from your tray.
  2. Rotate it 60° with the scroll wheel or R / E, and flip it with F or right-click.
  3. Place it so it touches one of your own blocks at a corner only — never along an edge. Other colours may share edges with you freely.
  4. Red ghosting means the placement is illegal. Green means click to commit.
  5. If you have no legal move left, retire and the turn passes on.

Modes

Free-for-all pits all four colours against each other. In Teams mode you control Blue and Red against the computer's Yellow and Green — teammates sit diametrically opposite, so think about opening lanes for your partner while sealing theirs.
