Akari And Sudoku
In akari, the grid must be filled with light bulbs so that every square is illuminated. When a light bulb is placed in the grid, it illuminates every square in a horizontal or vertical line that isn't blocked by a black square. The rules are simple to remember, but create a complex logical world that sudoku solvers will appreciate.
