Hashi help

Hashi (short from Hashiwokakero) also known as Bridges is a logic puzzle with simple rules and challenging solutions.

The rules are simple.
Hashi is played on a rectangular grid with no standard size. Some cells start out with numbers from 1 to 8 inclusive; these are the islands. The rest of the cells are empty. The goal is to connect all of the islands into a single connected group by drawing a series of bridges between the islands. The bridges must follow certain criteria: They must begin and end at distinct islands, travelling a straight line in between; They must not cross any other bridges or islands; They may only run orthogonally; At most two bridges connect a pair of islands; and The number of bridges connected to each island must match the number on that island.
