The rules:

Normal sudoku rules apply. Place the digits 1-9 exactly once in each row, column and box.

Sandwich Sums: Digits outside the grid indicate the sum of the digits that are placed between the 1 and 9 in that row or column.

Counting Circles: Every digit N appearing in a counting circle appears N times in counting circles. e.g. if there is a counting circle with a 7 in it, there must be exactly 7 counting circles in the puzzle with a 7 in them.
