Flood Cube — the 3D flood-fill puzzle game
Flood Cube is a free, browser-based strategy puzzle that reinvents the classic "flood-it" color game in three dimensions. Instead of filling a flat grid, you flood the six connected faces of a rotating cube, turning the entire surface a single color within a strict "Par" move limit. Every puzzle is solvable — the real challenge is doing it within Par, a move budget we calibrate from real player results to stay tough but fair. Success comes down to planning, spatial reasoning, and efficient color choices — never luck.
