Play in Sudokupad

Normal sudoku rules apply.

Disjoint groups--Cells that appear in the same position relative to their box must not contain the same number.

Circles--The nine circles form a set of the digits 1-9

Helper Cells--There is one helper cell in each box, row, and column. The value of this cell is its own box number (read left to right from the top). The nine helper cells form a set of the digits 1-9.

Arrows: Values on an arrow sum to the value in the attached circle. Values may repeat on an arrow.
