In the standard form of this puzzle, a grid is provided with empty or filled circles in some cells. A single closed loop is to be drawn through some cells so that the loop passes through every circle, turning in each filled cell (but not turning just before or after the filled circle), and going straight through empty circles (but turning before and/or after the empty circle).
