How to play flood fill

Inkspill is a flood fill color puzzle: grow the color from the corner until the whole board is one color.

Your ink starts in the top-left corner. Each move, pick a color: the ink turns that color and swallows every touching cell of it. Fill the whole board before you run out of moves.

Tips

  • Pick the color that swallows the most cells, but watch for colors you can wipe out completely: every color that disappears makes the rest easier.
  • Grow toward the middle first. From the center your ink touches more regions at once than from an edge.
