Logic Masters Deutschland e.V.

The series:

This is the third installment of what is now apparently becoming a series that started with original arROw SudOkU, which turned out to be very hard and so it was followed by kind of a remake arROw SudOkU rEduX with the same break-in but easier (but still quite hard). This one (very different from the first two) should be the easiest of the three.

Big thanks to Piatato for his test solve and feedback.


The rules:

Normal sudoku rules apply, in addition to that:
- each line contains a set of consecutive digits in any order without repeats (standard renban)
- inequality signs indicate inequality between the digits in the corresponding cells.


A small hint:

There are various ways how to resolve the cycle conundrum, if you have trouble breaking it, there is a little observation about renbans that you might find useful (highlight the text below to see it):

If 3 renban lines A, B and C of length 3 form a cycle (i.e. some number in A is smaller then some number in B, some number in B is smaller than some number in C and some number in C is smaller than some number in A), then A, B and C together contain at most 5 different digits.

Have fun with the puzzle, I'll be happy to read your comments/feedback.
