Bridges is the second daily board on Quorum. Islands sit on a grid, each with a number. Draw straight bridges along rows and columns so every island has exactly its number of bridges.
A line takes one or two bridges, bridges never cross, and when you are done every island can be reached from every other. There is exactly one answer, so nothing needs guessing.
The board is the same for everyone and changes at midnight UTC. Quick days take about a minute, Hard days about three.
