Not Between Sudoku
(Published on 29. May 2021, 04:07 by stephane.bura)
Normal Sudoku rules apply.
Circled digits at the ends of a line must be different.
Digits on a line must not be between the two ends, can't be equal to the ends and they must all be different.
The ends and the digits on the line add up to the same number.
All the lines sum to a different total, except for the dotted lines which share the same sum.
For instance, r3c1 + r2c2 = r1c1 + r2c1, all these cells are different (obviously in this case), r1c1 and r2c1 are not between r3c1 and r2c2, and this sum is unique in this grid.
Enjoy!
Solution code: Column 2, column 3

Very nice, I got stuck for a while cause I forget the different total rule, after that the solve was smooth and interesting.

Stared at it for a little while before re-reading the rules and noticing all numbers on the line have to be unique! Thanks for another lovely puzzle :)

Does the sum of a line include the two ends in circles?

No. r3c1 + r2c2 = r1c1 + r2c1 and that's the value we're considering.
Although, if you counted them, it would still work regarding uniqueness :)
