Puzzle 191 ("Nine Boxes", Slitherlink)

Another day, another Slitherlink.  This one was also inspired by a wolog theme, but being the constructor I am, I decided to expand the scope of the theme a bit.

My main goal with this puzzle was to make a region that is densely clued but still ambiguous for large portions of the solve.  This is still fairly tough for me to pull off, but I think I did it here.

Puzzle 190 ("USSQT Redux", Sudoku)

I constructed a Classic Sudoku for the 2023 US Sudoku Qualifying Test!  (Past me would be in shambles rn.)  Wei-Hwa essentially constructed an entire contest in three days; I decided to chip in a random Sudoku because I had no intentions of actually competing.  

The grid below is not the puzzle appearing on the actual test.  Instead, it was the "first draft" of that puzzle -- one I sent to Wei-Hwa first before finding the harder grid.  (At least, it's harder according to Andrew's Sudoku Solver; the USSQT puzzle has grade 82, while the below puzzle has grade 51.)
