    How to do this

    1. Find Hashiwokakero puzzles to solve.

    Typically involves

    Played on a rectangular grid. Cells start out with (usually encircled) 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 by drawing a series of bridges between the islands. The bridges must follow certain criteria:
    1. They must begin and end at distinct islands, travelling a straight line in between.
    2. They must not cross any other bridges or islands.
    3. They may only run perpendicularly.
    4. At most two bridges connect a pair of islands.
    5. The number of bridges connected to each island must match the number on that island.
    6. The bridges must connect the islands into a single connected group.
