Flood Fill

Strategically expand your colored region to flood the entire board within a limited number of moves.

Tutorial: Flood Fill

How to Play:

  1. The board is a grid of randomly colored tiles. You control the top-left corner region.
  2. Each turn, select a color from the palette at the bottom.
  3. Your region changes to that color and expands to absorb all adjacent tiles of the selected color.
  4. Keep flooding until the entire board is one color.
  5. Complete the puzzle before you run out of moves to win.
  6. Par score shows the optimal number of moves for each puzzle.

Pro Tips:

  • Choose colors that create the largest immediate expansion.
  • Look ahead — some colors set up bigger moves later even if they don't expand much now.
  • Colors that appear frequently on the board's edge are often good early picks.
  • Avoid painting yourself into a corner — plan a few moves ahead when possible.
