Play this puzzle online at the Daily Sudoku site
There are also two other 239 XY-Wings tucked away in boxes 4 and 7
(1 definitely comes out in one) and I suspect that the 39 W wing
in c89 is also a one stepper-(without the 'grade' button working
to confirm it I can't be bothered to finish all variants)
