Sightline Grid

Sightline Grid takes the lookout puzzle to a 7×7 night sky. Gold number cells are watchtowers. Each one sees along its row and column until a wall or the edge, and the number says how many open cells it sees, counting itself. Place walls on empty cells until every tower is right. Walls can't share a side, and the open sky must stay in one connected piece. Here, though, you don't wait for the check to find out about touching walls: they glow red the moment you place them, so you can fix them right away. The extra row and column make long sightlines and deeper chains of logic than the usual 6×6. Check Sightlines when you're done. Undo is unlimited, the counter tracks every action, and each sky has exactly one solution. Works offline. No ads. No purchases.
