All bridges run horizontally or vertically, starting on one island and ending on another. Each pair of islands could be connected to 0, 1 or 2 bridges in up to four directions.

No bridge ever crosses another bridge. When the puzzle is complete, it must be possible to walk from one island to any other via the bridges.
