Place bulbs to light every cell · no two bulbs see each other and numbered walls count their neighbours. A classic light-up logic puzzle
About Akari
Akari is a light-placement logic puzzle · you put bulbs on the grid so every cell is lit, no two bulbs see each other, and each numbered wall touches exactly that many bulbs.
How a round works. Tap cells to place bulbs. Light shoots down each row and column until it hits a wall, and the numbers tell you how many bulbs each wall must touch · deduce the only legal arrangement.
Part of Logic Puzzles. Akari is both its own game and a tab inside the Logic Puzzles hub, so you can play it on its own or alongside the related games.
Part of PlayMemorize, a passion project from Christoffer De Geer. It runs entirely in your browser.
