Sandwich is a logic puzzle invented by Naoki Inaba (Japan). A rectangular or square grid contains numbers in some cells. The task is to blacken some empty cells according to the rules: - All white cells must be divided on regions having the size of exactly three cells. - Two black cells must not be orthogonally adjacent. - Each region contains a number. - A number indicates how many black cells share an edge with that region.
