Cagy Zeros Return

Extended Sudoku rules apply, place the digits 0-9 in each row, column, and box, however there will be one digit in each that does not fit. This digit can vary between rows, columns, and boxes and needs to be determined by the solver. Killer cages: Digits in cages add up to the total in the corner. Phistomefel Ring: Digits form a proper Phistomefel Ring.
