Marcus White
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.
