The rules

  1. The number on an island is how many bridges touch it.
  2. Bridges run straight, up-down or left-right, and never cross.
  3. Two islands share at most two bridges.
  4. In the end every island can be reached from every other.

Drag from an island toward its neighbour to build a bridge, or tap the water between them. Again makes it a double, and once more clears it. With a keyboard: arrow keys move between islands, Shift with an arrow builds.
