Akari Puzzle app analytics for December 23

Akari puzzle is a kind of pencil puzzle where all cells are lit-up by placing lightbulbs and no lightbulbs shine on each other. Rule is very simple. 1. Lightbulbs shine every cell vertically and horizontally until they reach a black cell or the boundary. 2. Numbers in some black cells denote the number of lightbulbs in adjacent cells. 3. Lightbulbs themselves are not lit by other lightbulbs.
