About Akagram: A Logic Puzzle of Light and Deduction
Akagram is a relaxing logic puzzle game built around a single elegant challenge: place light bulbs to illuminate every empty cell on the grid. Light travels horizontally and vertically until it hits a wall, and no two bulbs may shine on each other. Several views of the game show a four-by-four grid made up of white, dark gray, and yellow squares.
What sets Akagram apart from classic light-up puzzles is its additional layer of deduction — numbers outside the grid tell you exactly how many bulbs belong in each row and column, stacking on top of the wall-adjacent clues to give you more to reason through. The result is a puzzle that rewards careful, methodical thinking. Levels range across a variety of configurations, and dedicated daily challenges and a Time Attack mode keep the experience fresh beyond the main puzzle set.
How to Play Akagram: Illuminate Every Cell
The goal is to light up every empty cell on the board while satisfying every clue. Bulbs cast light horizontally and vertically until a wall blocks the beam, and two bulbs must never fall within each other's line of sight.
Wall numbers indicate how many bulbs must sit directly adjacent to that wall — horizontally or vertically. Numbers placed outside the grid specify how many bulbs belong in the corresponding row or column. Filling the entire board with light and meeting all of these constraints simultaneously completes the puzzle.
