Competitive Tetris
(Published on 23. September 2022, 09:00 by Bremster)
Another one of my puzzles where I am exploring making things that are significantly harder than my normal creations. I hope you enjoy.
Puzzle Rules:
- Normal Sudoku rules apply.
- Each of the indicated diagonals must also contain a set of the digits 1-9 without repetition.
- Digits in cages must sum to the number in the top left corner of the cage. Digits may not repeat within cages.
- Columns 159 are column indexing. Digits in red-shaded cells in column 1 indicate the position of 1 in the corresponding row. The same is true in columns 5 and 9 for 5's and 9's respectively.

Solution code: Row 2 then row 8. 18 digits, no spaces or punctuation.

What a great puzzle! Some lovely interactions with the cages, as well as some surprising restrictions using the diagonals and 159 constraints. Thank you very much!

Believe it or not I cried after solving this one. This boost my confidence in solving difficult sudokus.

Some interesting, and tough, deductions required. A good example of a good genre.

As a fan of 159 puzzles this is one of the best (and trickiest) i've solved. Love the minimalism.

Thanks @bremster for this puzzle. Beautiful intercation in diagnoals and 159 and fewest of cages.

Never did find the break-in, but still managed to solve it with some bifurcation. Clearly, I had some idea where/what the break-in was or bifurcating wouldn't have helped, just couldn't quite nail it down.

Nice break-in with beautiful interactions all around.
