Heyawake - online puzzle game

overview

Heyawake is a room-based logic puzzle. Shade cells black to satisfy each room clue while preserving the global white-cell constraints.

rules

• Each numbered region must contain exactly that many black cells.
• Black cells cannot touch horizontally or vertically.
• A straight orthogonal white run cannot pass through more than two regions.
• All white cells must remain connected as one group.

controls

• Tap/click a cell to cycle clear -> black -> white mark.
• Right-click to cycle in reverse.
• Use Check to validate current progress.
• Use Hint for one correction, or New Game for a new puzzle.

scoring

Faster solves with fewer moves and fewer hints score higher. Check helps diagnose conflicts quickly, while frequent hints reduce final score quality.

tips

• Start from small rooms and exact clues like 0, 1, or room-size limits.
• Use room borders to watch straight white runs crossing too many regions.
• If a black placement isolates white space, revert immediately.
• Use Check before Hint to understand which rule is currently failing.
