Akari,
place bulbs, light the board.
Bulbs light their row and column until a wall blocks them. No two bulbs may shine on each other; every numbered wall demands an exact bulb count in its neighbours.

How Akari works,
in short.
- Step 0121
Light every white cell.
Place light bulbs on the white cells so that every white cell ends up lit. A bulb lights its own cell and shines along its row and column, stopping when the beam hits a black wall or the board edge.
- Step 0221
Tap a cell to cycle Empty → Bulb → Dot.
A numbered wall must have exactly that many bulbs in the four cells directly touching it — up, down, left, and right. Dots are personal markers for cells you have ruled out as bulbs.
- Step 0321
No bulb shines on another.
Two bulbs that share an unbroken row or column segment would shine on each other — that is forbidden. The puzzle is solved when every white cell is lit, every numbered wall has the exact bulb count, and no bulb shines on another.
