How to Play Flood Fill
- The grid starts with cells of different colors. Your goal is to make the whole grid one color.
- Tap a color button to change the top-left region's color — it absorbs all adjacent cells of that color.
- Each move, your connected region grows by absorbing matching neighboring cells.
- Fill the entire grid within the move limit to win.
- Use fewer moves than the par to earn more stars.
- Complete 30 levels plus daily challenges for endless fun.
Tips & Strategy
- Plan ahead — think 2-3 moves in advance rather than reacting to the current board.
- Aim to absorb the largest possible region each move — bigger absorption means faster filling.
- Don't waste moves on small color pockets early — they'll get absorbed naturally later.
- Watch the edges and corners — isolated color regions there are the hardest to reach.
- If you're over the move limit, restart and try a different color sequence.
- In daily challenges, speed matters — practice pattern recognition to solve faster.
