Global vs Global
(Published on 27. August 2026, 21:33 by Killer Joe)
Hello.
This particular shape of arrow has worked very well for me in a few previous puzzles.
Both puzzles look very similar, but the ruleset and solve path are quite different. Eventually, these puzzles led to this idea: global vs global.

Global vs Global.
Normal sudoku rules apply.
Digits on an arrow sum to the digit in the attached circle.
Disjoint modular sets: Cells with the same relative box positions must contain digits from the same modular set (147), (258) or (369).
For example, if the first cell in box 1 contained a 5, every first cell of each box must contain a digit from (258).
Global entropy: every 2x2 in the grid must contain at least one low digit (123), one middle digit (456) and one high digit (789).
Have fun.
Solution code: Row 9, first 6 digits.

Once break in is solved, puzzle gets trivial as both constrains combined are VERY restrictive

an excellent juggle of entropy and modularity
