Hashi is a classic Japanese puzzle game. Each game of Hashi presents a map of circles containing numbers, called "islands". The number within each island determines how many lines, called "bridges", must be connected to the island. To win, all of the islands must be interconnected with the correct number of bridges in one continuous chain.
* Bridges may not be diagonal.
* Bridges may not cross another bridge.
* One or two bridges may connect a pair of islands.
