Saturated Island

This island already has all the bridges its number allows — no other connection can touch it.

How it works

  1. 1The 1 in the top-left corner already has its single bridge, running right.
  2. 2Its number is met, so nothing more may ever be added to it — not even a second bridge alongside the one it already has.
  3. 3The path down from it can therefore never carry a bridge at all.

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