- Normal sudoku rules apply.
- Global Entropy: Every 2x2 region must have digits of all three sets 123, 456, 789.
- A digit on an arrow indicates the length of the first non descending sequence of digits seen in that direction. For example, an arrow seeing a sequence of digits →247748 will have the digit 4, and an arrow seeing a sequence of digits →912376 will have the digit 1.

2* is bang on. Approachable for both aq and global entropy.

Bit tricky to see the arrows after colouring squares, at least on phone. Nice puzzle, thanks!

Fun puzzle! Very nice combination of constraints. Approachable puzzle, although there are a few average steps. Thanks

A very interesting combination of constraints. They worked together really well.

A criminally smooth break-in (and a lot more forgiving than a lot of your puzzles I've encountered! This is borderline approachable). Great stuff.

Super fun rule set. Easier and more straightforward to solve than it looks at first glance.
