Hello.

Draw a loop that moves strictly orthogonally and only turns on even digits.  

The loop does not cross itself but can touch itself horizontally and diagonally.

The loop moves clockwise and turns in the direction indicated by the digits as they appear on the num-pad.

2= up. (north)

6=right (east)

8= down (south)

4= left (west)

The odd digits on the loop inside a box will sum to the same value as the killer cage for that box. The loop visits each box at least once.

Multiple visits count toward the same total.

Normal 9x9 Sudoku rules apply. Place the digits 1-9 exactly once in every row, column, and 3x3 box.

The digits in a cage sum to the value in the top left corner of the cage.

Have fun.
