On the board there are islands - each circle's number shows how many bridges it needs.
Bridges run horizontally or vertically from island to island: straight, without crossing another island.
Connect all the islands so that everything stays connected in the end and every island has exactly as many bridges as its number says.
Example
For parents
What does this exercise practice?
Bridges trains careful looking and planning - every number decides how many bridges end at the island, and all islands have to stay connected.
Common pitfalls
An island fills up faster than expected. It helps to serve the islands with high numbers first and check at the end whether every island reached its number.
How to practice at home
Play it with paper strips - two strips side by side are a double bridge. That makes it easy to see which island still needs bridges.
