Akari

About Akari

A Japanese logic puzzle where you place light bulbs to illuminate a grid. Each bulb lights up its row and column until blocked by a wall. Numbered walls show exactly how many bulbs must be adjacent.

Description provided by GameZipper.

How to play

1. The grid has white cells (where you place bulbs) and black cells (walls). Some walls have numbers 0-4.
2. Click or tap a white cell to place a light bulb. The bulb illuminates its entire row and column in both directions until hitting a wall.
3. A numbered wall must have exactly that many bulbs in the four adjacent cells (up, down, left, right). A '2' wall needs exactly 2 adjacent bulbs.
4. No two bulbs may illuminate each other. If two bulbs are in the same row or column without a wall between them, that's an error.
5. The puzzle is solved when every white cell is illuminated by at least one bulb. Use hints if stuck!

Questions

What is Akari (Light Up)?

Akari is a Japanese logic puzzle where you place light bulbs on a grid. Bulbs illuminate their entire row and column until blocked by a black wall. The goal is to illuminate all white cells while following the numbered wall constraints.

How do numbered walls work in Akari?

Black cells with numbers (0-4) must have exactly that many light bulbs in the four adjacent cells (up, down, left, right). A wall numbered '3' needs exactly 3 adjacent bulbs.

What are the basic rules of Akari?

1) Click white cells to place or remove bulbs. 2) Bulbs illuminate their row and column until hitting a wall. 3) No two bulbs may illuminate each other. 4) Numbered walls must have the exact count of adjacent bulbs. 5) All white cells must be illuminated to win.
