Connect numbered islands

Bridges: free bridge logic puzzle online

Connect numbered islands with straight bridges. Each island's number is the total number of bridges that must touch it, and a double bridge counts twice. Bridges cannot cross, and all islands must join into one group.

Start here

Count the most bridges an island can still receive. Each clear path to a visible island can hold one or two bridges. If that total is the number the island still needs, place the full number of bridges each path can hold.

RulesLearn where bridges can run, how double bridges count, and how all islands connect. StrategyTrack how many bridges each island still needs, and leave a path that can join all islands.

How a turn works

Click a clear path between two islands to cycle through no bridge, one bridge, and two bridges. Paths that would cross a bridge or pass through an island stay blocked.
