10-in-9 calcudoku #1

(Published on 27. January 2020, 10:04 by Nylimb)

This is a variant of a calcudoku (also known as KenKen) puzzle, in which some cells contain 2-digit numbers.

Fill the grid with 1-digit and 2-digit numbers, so that every row and column contains each of the 10 digits, from 0 to 9, exactly once: Eight cells contain 1-digit numbers, and the other cell contains a 2-digit number (from 10 to 98).

Each cage indicated by the thick lines shows an arithmetic operation (+, -, x, or /) and the result of that operation applied to the numbers in the cage.

A digit can occur more than once in a cage, as long as the occurrences are not in the same row or column. It's also possible for two 2-digit numbers to occur in one cage, if they're not in the same row or column.

The puzzle is available on Penpa.

Solution code: Column 6 and column 7. Include both digits of the 2-digit numbers.

Mind-bending! After a couple of failed attempts I finally got my act together. Superb logic throughout.

To zorant: The solution that you described in your hidden comment appears to be correct. But the solution code should not have any commas between the numbers; it should be just a string of 20 digits.

@ragna, yes, the numbers may be in any order. The largest number is divided by each smaller number in succession to give the result of the division.

The same is true for the minus operator: the smaller numbers are subtracted from the largest.

Short question:
Result 2/ means 2 1; 4 2; 6 3; 8 4.
Is it allowed to write 1 2;
2 4; 3 6; 4 8 ?

To zorant: I think your hidden comment was intended for a different puzzle, namely "WORTMISCHUNG - 3D Buchstabenrätsel",
