A collaboration puzzle, set by me and echoes!
Normal Sudoku rules apply. Digits in marked cages must not repeat, and must sum to the total given in the top left corner of the cage.
Solution code: Row 8, row 9.

Beautiful ideas which seem so simple once they are found. A very hard challenge worth taking on.

Astounding setting, what a gem of a puzzle! The opening really blew my mind off with such simple yet really elegant ideas, after that it still remained quite challenging but all were worth my efforts and I have a bright smile at the end :D

Is there a word for something that is simultaneously simple and complicated? This break-in was one of the most beautifully simplicated things I have ever seen. Absolutely amazing.

Insane collab. That break-in is NASTY. And mid-solve is challenging too. The puzzle never lets go until the last 15 digits. Splendid!

A hard puzzle with a very clever break-in. All my puzzle solving experience really came in handy for this one.

It is the giraffe of sudoku: a completely unlikely yet also inexplicably elegant construction & force of nature.
