The rules
- Build bridges in straight lines, across or up and down, from one island to the next.
- Each island needs as many bridges as its number.
- Two islands can have at most 2 bridges between them.
- Bridges may never cross.
- In the end, all islands must be joined together.
Two ideas that help
Check how many bridges an island can get from other neighbours. If that is not enough, it needs a bridge here.
If a bridge must be there, no other bridge can cross it.
Playing it in Quirk
Tap 2 islands in turn, or drag from one to the other, to add a bridge. Do it again for a second bridge, and once more to remove both.
