In 2021, I created my first Sudoku puzzle, “On the Quad”. I stayed with the theme and the single constraint for three more puzzles before branching out in the fourth to eliminate all given digits and add a diagonal constraint.
If you’re new the variant Sudoku, I hope these serve as a good introduction for you, as they served as a good introduction to setting puzzles for me.
Freshman year is a GAS. The campus feels new and fresh, and you are learning important things. Like that big four-sided area there in the middle of campus, that’s The Quad.
Sophomore year isn’t quite the GAS that freshman year was, but you still enjoy The Quad. It seems different. Not much, but they say you can’t step in the same stream twice, and enough has changed to make the campus slightly less welcoming than it was.
Sophomore year was fun, but now you’re out ofGAS and stuck on campus over the break. The one constant is The Quad. Someone has cleared out some of the old shrubbery and planted some new flowers, but it’s still the same old Quad you know and love. It almost makes having no place to go home to bearable.
Senior year is here, and you’ve really made a home for yourself on campus. You’ve now mastered The Quad. You take shortcuts across the quad to get where you need to go, and it helps you avoid people–and given digits.
