Easy to Hard
Join the numbered islands with bridges, until every island is connected.
Hashi, also called Bridges or Hashiwokakero, is a puzzle of numbered islands. You join the islands with straight bridges so that each island has as many bridges as its number. Bridges run across or down, never cross another bridge, and there can be at most two between the same pair of islands. When you finish, every island is joined into one connected network.
