HOW TO PLAY AKARI

Light every open square using pure logic.

Place bulbs so every white cell is illuminated, while respecting the numbered black cells and making sure no bulb shines on another bulb.

Light the grid Every white square must be illuminated by a bulb in the same row or column.

Bulbs cannot see each other If two bulbs share the same row or column with no black cell between them, the placement is invalid.

Respect the numbered cells A numbered black square must touch exactly that many bulbs on its four sides.

Use marks to reason Mark cells, test deductions, and solve by logic alone until the entire board is lit.
