Featured Puzzle Akari (Light Up) #4
Place light bulbs in the grid in such a way to illuminate all of the unlit cells in the grid, using number clues and walls. Numbers on the walls indicate how many bulbs are placed orthogonally adjacent to them. Walls also block light.
- Bulbs shine in all four orthogonal directions, until blocked by a wall or the border. They do not light up any cells in diagonal directions.
- You may not place a bulb in the light path of another bulb.
- Numbered walls indicate bulbs placed orthogonally adjacent to them. For example, a wall numbered 4 will have a bulb above, below, and to its left and right.
- Bulbs placed diagonally adjacent to a numbered cell do not count toward the limit.
- Walls without numbers may have any amount of bulbs placed next to them, as long as all other rules are followed.
