Key Strategies

  1. Start with islands that are nearly full

    An island with value 1 that has only one neighbor must connect to that neighbor. Islands with value 4 on a corner can only have 2 neighbors — they need 2 bridges each.

  2. Avoid isolating groups

    All islands must form a single connected network. After each bridge, check that you haven't created an isolated sub-group that can't grow large enough to connect to the rest.

  3. Use capacity limits

    Each pair of islands can have at most 2 bridges. If an island of value 2 has two neighbors but only one bridge slot available (due to crossing restrictions), that neighbor must take both bridges.

  4. Bridges cannot cross

    Horizontal and vertical bridges may not intersect. Use this constraint to eliminate possible bridge placements and force alternatives.

Put It Into Practice

The best way to improve is to play regularly. Start with an easy puzzle and apply these techniques one at a time.
