Snail Race
(Published on 23. January 2023, 16:00 by Blobz)
Five snails line up on the starting grid -- the starter's pistol goes off... and... after a bit of a slow start, they head towards the finish line. It's a close (but slow) race. Eventually, even the stragglers make it across the line.
Each snail leaves a different type of trail: German Whisper, Renban, Region Sum, Entropic, and Modular. Which snail leaves which trail must be deduced by the solver.
German Whisper: Adjacent digits along the line differ by at least 5.
Renban: The line contains a set of (non-repeating) consecutive digits in any order.
Region Sum: Digits along the line have an equal sum N within each box it passes through; If the line passes through the same box more than once, each individual segment of the path within that box sums to N separately.
Entropic: Every three adjacent digits along the line must contain a low (1-3) digit, a middly (4-6) digit, and a high (7-9) digit.
Modular: Every three adjacent digits along the line must be drawn one from each modulo group: {1,4,7}, {2,5,8}, {3,6,9}.
Digits in cages sum to the clue in the top left corner, if given.

Great fun in eking out little deductions for the properties of the different lines!

This was very fun, and the logic was lovely. I have never played a couple of these constraints. It felt like a nice introduction to them. Thanks!!
