About Flood Fill
Flood Fill is a color strategy game. Each move recolors the region in the top-left corner, merging it with neighbors of the chosen color. Turn the whole board one color within the move limit — or beat the reference solution.
Play a new daily puzzle every day, or pick Easy, Medium or Hard in practice mode for unlimited puzzles.
How to play
- Each move picks a color: the region containing the top-left cell becomes that color and merges with neighbors of that color.
- Turn the whole board one color within the move limit.
- The limit comes from a greedy look-ahead strategy — beat it with fewer moves!
Undo takes moves back; Reset starts over.
Tap a color below: the top-left area turns that color and swallows matching neighbors.
Tips & strategies
- Pick the color that absorbs the most cells, but also think one move ahead.
- Expand towards the center first — it opens up the most borders.
- Leave isolated single cells for the end.
