Bridges Without Crossings

Meet every island’s bridge-dot count and connect all islands in one network.

How to play

Choose two nearest visible islands in the same row or column to add a single bridge. Choose the same pair again to remove it. Bridges cannot cross or pass through another island.

Filled dots count existing bridges; empty dots show what is still needed. Every island needs its full count and the entire network must connect. A bridge hint checks complete continuations. Undo and Reset keep discoveries; Next puzzle waits for you. No timer or penalty.
