Play in Sudokupad
Place the digits zero, one, two, three, four, five, six, seven, and eight in every row, column, and box.
Spelling and counting letters rules.
Global Set Constraint: In every 2x2 square, there must be at least one digit spelled with three letters, one with four letters, and one with five letters (standard English spelling seen above).
Cages: The given number for each cage is the sum of the number of letters for the digits in the cage (a cage marked 6 could include the digits one and two).
XV rules:
Cells connected by an X indicate digits that sum to 10.
Cells connected by a V indicate digits that sum to 5. The V also indicates that the digit on top is greater than the digit on the bottom.
Not all XV markings are necessarily given.
Solution code: Row two

Pretty fun! Not a big fan of the "top digit of V is greater than the bottom" rule, because it's basically optional until the very end, when I'm trying to figure out which set of 9 should be digit A vs digit B.
