    Definitely completed this in strict numerical order (all the 1s, then all the 2s…) since it looked like that was possible and I was curious to see if it worked. The geometry is tight enough that even when you get up around 5-6 and the givens are pretty sparse, there’s plenty of information.

    Pretty elegant, easy solve, but very beautiful at the same time. Liked the additional logic that if a number is placed it immediately restricts placing that same number in adjacent blocks, eg. the 3 in col 2 in block I, restricts the 3s in blocks IV and VII to col 1 and cols 3+4,
    so that there is a 3 in all 4 columns of those 3 blocks.
    Fave variant !

    The title of the puzzle and the locations for the digit 1 telegraphed the theme to me. This is the first Tile Sudoku I’ve ever solved, and it certain introduced me to some of the unique geometric constraints. 🙂
