Akagram

Akagram is a relaxing logic puzzle game where you place light bulbs to illuminate every empty cell. Follow the numbered clues and keep bulbs from shining on each other. Unlike classic light-up puzzles, Akagram adds row and column clues for an extra layer of deduction. Explore a variety of levels, solve daily challenges, or race the clock in Time Attack.

Place bulbs to illuminate every empty cell. Light travels horizontally and vertically until it hits a wall, and bulbs must not shine on each other. Match all clues: wall numbers count adjacent bulbs (no diagonals), and edge numbers count bulbs in each row or column.

Click or tap to place or remove bulbs. Use the × tool to mark cells where no bulb belongs, and the on-screen buttons for undo, redo, restart, and hints.
