Bridges is one of Simon Tatham's portable puzzles. Each circle is an island with a number on it. Draw horizontal and vertical bridges between islands, up to two between any pair, so that every island has exactly as many bridges as its number and all the islands join into one connected group. Bridges may not cross.
Every puzzle is generated fresh, with several sizes and difficulty levels, and each one has a single solution you can reach by logic alone.
Controls

Tips for Bridges
Start with islands that can only be finished one way, such as a 4 in a corner.
An island with a 1 next to another 1 cannot link to it if that would cut the pair off from everything else.
Use the finished islands to rule out bridges for their neighbours.
