Editorial Overview & Provenance

Color Flood Fill is a strategic puzzle game where players must unify a multicolored grid into a single hue within a limited number of steps. Originating from classic flood-fill algorithms, this browser-based adaptation offers instant accessibility with no downloads required. The goal is simple: flood the connected matrix by selecting colors from a palette, expanding your controlled area until the entire grid matches. Perfect for quick sessions, it challenges spatial reasoning and efficiency.

Core Gameplay & Mechanics

Each level presents a grid filled with random colors. Players select a color from the palette to flood the connected area starting from the top-left corner. The goal is to transform the entire grid into one color before step limits expire. Points are awarded based on speed and minimal moves. Failure occurs if steps are exhausted prematurely. The learning curve is gentle but deepens as grids grow larger, demanding foresight to maximize each flood's coverage.

Exact Control Mapping & Input Guide

  • Primary: Click or tap palette colors to flood the grid
  • Secondary / Quick-Reset: Press 'R' to restart instantly
  • Mobile Touch: Tap color buttons below the grid; swipes ignored

Strategy, Pacing & High-Score Heuristics

  • Prioritize colors that border the most unflooded tiles to maximize coverage per move.
  • Avoid switching colors too frequently; plan 2-3 moves ahead to chain floods efficiently.
  • Watch for bottlenecks where a color blocks expansion—address these early.
  • On larger grids, balance between corner growth and center control to avoid stranded tiles.

Frequently Asked Questions

How do I minimize moves?
Target colors that expand into multiple directions simultaneously, reducing isolated patches.
Why does the grid sometimes stall?
You've trapped unflooded tiles—always check for color paths to the outer edges.
Are larger grids harder?
Yes, they require more foresight but follow the same principles—control chokepoints early.
