(Published on 20. November 2024, 01:45 by Oddlyeven)
Quattroquadri: Put the digits 1 to 9 into each box such that no digit repeats in any row or column.
Dots: Digits on a black dot are in a 1 to 2 ratio. Digits on a white dot are consecutive.
Tetrominoes: Divide the grid into tetrominoes (sets of four orthogonally connected cells). Dots always lie on a boundary between two tetrominoes. Adjacent digits in a tetromino must have a difference of 4 or greater.

Very nice. 2 star to me. Thought long forgetting all dots divide regions. Also thought about a 9x9 puzzle with similar rules... great fun. Thanks for this joyful snack.

Nice puzzle, although easier than 3 stars in my opinion. Also, your solution code description says column 9 ;)
Fixed, thanks! -Oddlyeven
