Spot The Differences (Redux)  
So tonight I'm putting together a packet of "Not Sudoku" Puzzles for the WSC in two weeks (where it seems both Wayne Gould and Maki Kaji will be making guest appearances).

In putting together this hand-out, I realized it was time to fix the one puzzle that I had made overly difficult based on an error in my multi-cell subtraction considerations. I've made a much better subtraction-only puzzle that actually has a fair solution path.
