About the game

Every empty cell on the grid has to end up lit, and that is the whole job. Bulbs send light along rows and columns until a wall stops it, and two bulbs may never shine on each other. Numbers on walls tell you how many bulbs touch that wall, and numbers on the board edge count bulbs in a whole row or column.

Those extra edge clues are what set Akagram apart from the usual light-up style. You start by finding cells that can only go one way, then let each placement narrow the next. Pick regular levels for a slow session, check the daily challenge, or switch to Time Attack when you want some pressure.

How to play

• Click or tap a cell to place or remove a bulb. Use the × tool to mark cells that must stay empty.
• Light every empty cell, and never let two bulbs face each other along a row or column. Walls block the light.
• Wall numbers count bulbs in the four neighboring cells, no diagonals. Edge numbers count bulbs in that row or column.
• Buttons on screen handle undo, redo, restart and hints. Scroll or pinch to zoom, drag or swipe to move around.
