Connect the circles to one-another along the grid lines. Your goal is to have as many paths from each circle as the number in the circle indicates, and to have all the circles connected together in a single network. In the standard (doubles) mode, you can have no more than two connections between any two circles. The puzzles are all solvable, but their solutions may or may not be unique.
