Help

  1. Each number tells you exactly how many bridges must touch that island.
  2. Connect the nearest island in a straight horizontal or vertical line. A pair can share one or two bridges.
  3. Bridges cannot cross one another or pass through an island.
  4. Every island must belong to one connected network.

A bridge can fit two islands and still split the network. Check both the local numbers and the whole picture.
