How to Play Filler (Color Flood)
Filler (also commonly called Flood-It or Color Flood) is an addictive spatial deduction and pathfinding puzzle game. Your objective is straightforward: expand your territory until the entire board is converted into one single uniform color within the allowed move limit.
Core Game Mechanics
You always begin controlling the single starting square positioned in the top-left corner of the grid (coordinate 0, 0). Five curated color choices are lined up on the control palette directly beneath the puzzle board:
- Choosing a New Hue: Whenever you tap any color button, every cell within your currently captured territory immediately shifts to that chosen color.
- Absorbing Neighbors: Any adjacent uncaptured squares sharing that exact new color are instantaneously absorbed into your expanding kingdom.
- Chain Reactions: As your territory balloons across the grid, a single well-timed color swap can absorb dozens of connected cells at once!
- The Move Counter: Each turn ticks down your move budget. Clear the board before you run out of moves to achieve victory.
Mastery Tips & Strategies
🔭 Look Two Moves Ahead
Don't just pick whichever color offers the highest immediate tile count. Often, picking a smaller 2-cell bridge reveals a massive 15-cell cluster on your subsequent turn.
🎯 Unlock the Corners
The far corners (top-right, bottom-left, bottom-right) are the hardest squares to reach. Steer your expansion diagonally toward them early to prevent stranded single tiles at the endgame.
⚡ Eliminate Bottlenecks
Watch for single-tile choke points dividing large color clusters. Breaking through a narrow bridge connects your cluster with the entire opposite half of the grid.
🚫 Avoid Zero-Gain Moves
Tapping a color that touches zero adjacent squares wastes a move without expanding your territory. Keep an eye on your perimeter to maximize every tap.
