    Numbered islands.

    Each island shows how many bridges should connect it. Bridges run horizontally or vertically.

    Draw one or two bridges.

    Tap an island, then tap a second one in the same row or column to cycle the bridge between them: zero → one line → two lines → zero. Match each island's number. Bridges never cross.

    All islands connected.

    Every island's number matches and the network is reachable from any island. That's the solve.
