Normal sudoku rules apply.
Palindromes: Digits along lines form palindromes, which read the same in both directions.
Little Killer Sums: Digits along indicated diagonals sum to the totals given outside the grid, and may repeat if allowed by the other constraints.
Solution code: Negative diagonal (r1c1 to r9c9), then row 8. 18 digits, no spaces.

Got a chance to revisit this puzzle after a long time and wow...
Brutally clever and beautiful, I don't know what to say more. Even after the clever break-in I still struggled so hard to make it through (especially near the end), truly a crazy experience in my lifetime. Still loved it!!

Wonderful puzzle. The break in was amazing, and the ending with the 45 diagonal was just brutal but I managed to crack it.

Very challenging puzzle, not least because it's covered in pawprints, if you catch my drift :3 Thanks!

This palindrome set-up looks awfully familiar gray!

Can't wait to see Simon solve this incredible puzzle, this looks insane and very delicate at the same time :)
