MISSING BREAKPOINTS Puzzle Instructions

Draw a single continuous loop in the grid using horizontal and vertical line segments such that the loop visits every square exactly once. It does not cross or overlap itself. It makes a 90° turn at every breakpoint, i.e., a square with a circle. There is exactly one turn between two consecutive circles that the loop visits. However, one or more breakpoints are missing. Locate these missing breakpoints equal in number as given in the puzzle.
