Window Watch

Window Watch is a pencil-and-paper logic puzzle on a 6×6 grid. Some cells hold numbers. A number tells how many open cells it can see looking up, down, left and right — its own cell included — until a wall or the edge stops the view. Your job is to decide which empty cells become walls. Two more rules keep it honest: walls may never touch each other by a side, and all open cells must stay connected in one piece. While you work, each number shows a small counter in its corner: how many cells it sees right now. When the counter matches, the number lights up. Press Check View when you think you're done; if something is off, the game names the reason — numbers don't match, walls touch or open cells are split — and marks the cells involved. Every layout is generated with exactly one solution. Undo has no limit and the action counter shows how efficiently you solved it. No timer, no ads, no network, nothing to buy.
