Made for a setting challenge by Ratfinkz about non-square grids. Thanks to the CtC discord for testing and feedback. Hope you enjoy!
- Tetroku: Fill every cell in a tetromino with a digit from 1-9. Digits may not repeat in rows or columns but may repeat in tetrominoes.
- XV: Digits joined by an X sum to 10. Not all Xs are given.
- Ambiguity: Each of the following 3 properties must be satisfied by all tetrominoes of exactly one shape (L,J,T). Those properties do not need to hold across tetromino borders.
- Counting: A digit in this tetromino counts how often that digit appears in all tetrominoes of the same shape combined.
- 6-Whispering: Orthogonaly adjacent digits in this tetromino differ by 6 or more.
- Sequential: Digits in this tetromino may not repeat and orthogonally adjacent digits in this tetromino differ by 1 (consecutive).
Hint: Think about the possible digits that can go into r5c2 based on the property of the T tetromino.
Solution code: Digits in row 3 left to right (6 digits)

@Gnubeutel: it's meant to be a deduction but I almost put it in the rules, so I don't have a problem it being discussed in public comments. The extra step is to show that no shape can have multiple properties because any combination would put too much pressure on that shape.

I was struggling with the Ambiguity rule. A clarification might have helped that each tetromino shape has to use exactly one of the properties, and it's a different property for each shape.
After i understood that, it turned out to be a great puzzle. (I hope that's not part of the deduction process. I'll delete the comment, if you want me to.=

Extremely satisfying little puzzle; a lot more approachable than it looks. Give it a go!

It's a great little oddity. Just different enough to throw you off but greatly approachable and fresh.

Lovely idea and beautiful presentation! It took me a while to fit all the (metaphorical!) pieces together but very rewarding once I did!
