So monumentally stuck on this puzzle that I'm thinking I misunderstood the rules. So... there's only ever ONE repeated 7, for example, in total, across rows, columns, and boxes? Not one for the rows, and one more for the columns, and one more for the boxes?
@shteev - correct. If a 7 repeats in a row, it must not also repeat in a box or a column.

A great idea and a great puzzle! People should definitely solve this first before attempting composite puzzles to familiarize themselves with the ruleset. Very original idea, although very demanding to meticulously pencilmark what can and what cannot be in the cells, as well as when the situation changes. Thanks, starwarigami!

Beautiful puzzle. The mid part of the solve is something.
Thanks a lot.
