Bridges

How to play

Connect every island into one network so each island has exactly its number of bridges.

• Drag from an island toward a neighbor to add a bridge.
• Drag the same pair again for a second bridge; once more to remove it.
• Bridges are straight (horizontal or vertical) and cannot cross.
• At most two bridges join the same pair of islands.
• Nothing is ever penalized: build, undo and experiment as much as you like.

Tips

• An island's number is how many bridge ends must touch it.
• Start with islands whose number already forces their bridges.
• In the end every island must be reachable from any other.
• A corner island needing four must run two bridges to each neighbor.
