Ray Count

Ray Count makes the lookout puzzle visible. Every number is a small lamp that shines in four straight lines. The number is how many open cells its light reaches, the lamp's own cell included. Walls and the edge of the board stop the light. Tap a number and its rays light up in yellow, showing exactly which cells it sees with the walls you've placed so far. It's the easiest way to understand a tricky count, and a nice way to learn the puzzle if it's new to you. Rules for walls: they never touch by a side, and all open cells stay connected. Count Rays checks your board and explains any problem. Warm paper tones, monospace numbers, unlimited undo. Every layout has a single solution. No ads, no internet needed.
