About this puzzle
35 islands on a 13×13 grid need 44 bridges between them. The biggest island number is 5.
5 islands need at least one bridge to every neighbour.
Where to start
A good first move: the island with the number 5 at row 9, column 1, which can see 3 neighbours.
At least once you will need to try a bridge in your head and see it fail one step later.
