Week 16 - Hint: SQ Sudoku
There's one (well, two) complicating factors in this SQ type of Sudoku puzzle. In addition to each row, column, and 3x3 box having digits 1-9, both of the initials "S" and "Q" are also populated with those digits... and no repeats with anything in the row, column, or 3x3 box.
If you're a little stuck, try starting with the shaded boxes that make up the letter "Q". There are 4 missing digits, right? Can you find the one box that can ONLY be one specific number?
(Extra hint... that one numbers is an "8"...)
Once you find the place for the "8", can you find another digit? Then another?
Have fun solving the rest!
