📖 About

Heyawake is a shading puzzle played on a grid divided into rectangular rooms. Each room may contain a number indicating how many cells to shade. The rules: no two shaded cells can share an edge, no three consecutive shaded cells in any row or column, and all white cells must be connected. Play Heyawake free online — pure deduction, no guessing!

🎯 Objectives

Shade the correct number of cells in each room while ensuring all white cells remain connected and no three consecutive shaded cells appear.

🎮 How to Play

Click cells to cycle through: empty, black, or white. Each room must have exactly its target number of black cells. No three black cells can be consecutive, and all white cells must be connected.

💡 Tips

• ✓ Start with rooms that have 0 black cells - mark all white
• ✓ Look for rooms where the target forces specific placements
• ✓ Avoid creating 3+ consecutive blacks when marking cells
• ✓ Use white connectivity to eliminate impossible black placements
