Rank Up 07 - Renban
(Published on 18. July 2024, 22:59 by ThePedallingPianist)
Sudoku: Within the main grid (inside the thick border), fill every cell with a digit from 1-5 such that digits do not repeat in a row or column.
Renban: The purple line contains a non-repeating set of consecutive values.
Even: The value in the grey square is even.
Full Rank: A value in an external cell represents the rank of the number formed by reading the digits in that row or column from that direction, where (1) is the lowest such row or column and (20) is the highest.
N.B. If two ranks are tied, the value in both external cells is the lower of the two ranks being shared. For example, if the lowest four ranks are "12453", "13524", "13524" and "15432", the values in the relevant external cells would be (1), (2), (2) and (4) respectively.
Solution code: Column 5 (far right) of the internal grid, top to bottom

This is my favourite of the ones I've solved so far, in a series of only hits. Every deduction feels great when you find it. Fantastic stuff!

I saw the break-in very quickly - nice!
Then got a bit frustrated and after ruling out some options, I took a bit of an intuitive flier that turned out to be correct without fully deriving all the logic.

Very fun and interesting puzzle. Lots of intricate logic in here. Very cool.

Another lovely one! Renban does a ton of work; it's really cool how few clues are needed for these.

Great puzzle! easily the hardest of the series so far. I couldn’t have done it if i hadn’t played the earlier ones yet.

Took me a few reads to understand the rules. Perhaps make it clear that the outer bounds consist of the nrs 1-20 (with an exception for duplicates).
Once I understood the rules it was a clear but fun solve path. I'd say 1 star once you figure out the break-in but 2 for the actual break-in itself
