Maxi Loop

From WPC unofficial wiki

Rules[edit]

Draw a closed loop passing through the centres of all cells horizontally and vertically. The numbers in a thickly outlined region indicate the highest number of cells the loop passes consecutively in that area. This number must be achieved at least once.
