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.

Light up every empty cell to solve the puzzle! Place bulbs so their light travels horizontally and vertically until it reaches a wall. Bulbs must never shine on each other.

Numbers on walls show how many bulbs must be placed directly beside them, horizontally or vertically. Numbers outside the grid show how many bulbs belong in that row or column. Illuminate the entire board and satisfy every clue to win.
