How to play

  1. Your territory starts at the top-left corner.
  2. Click a color in the palette to flood-fill your region with that color.
  3. Any cells of the chosen color adjacent to your region get absorbed.
  4. Goal: make the entire grid one color in 25 moves or fewer.
  5. Plan ahead — pick colors that absorb the largest neighboring regions.

The top-left region is your territory. Click a color to flood-fill it — any connected adjacent cell of your current color gets repainted. Capture the entire grid before you run out of moves!
