Remaining-Count Cap

No single connection can carry more bridges than this island still needs.

How it works

  1. 1The 3 in the top-left corner already has a double bridge running right, so only 1 of its 3 bridges is still to place.
  2. 2No single connection can carry more than an island still needs.
  3. 3So the path down from it can never be a double bridge: at most a single bridge fits there.

Even maxing out every other connection would leave this island short — so this connection must carry the difference.
