Standard Sudoku Rules apply to the final numerical layout.
An Arrow in a cell indicates that the cell's value is N, and the Nth cell in the direction of the arrow will have a digit that is consecutive to N. For example, a cell with a 4 and an arrow means that the fourth cell in the direction of the arrow will be either 3 or 5. All possible arrows are indicated.

Setter's Notes :: January 25, 2021 :: Once I got the main idea in my head, I think I experimented with about two dozen of these, many of which "collapsed" almost instantly and with far too many digits that required no thought. I'm fairly satisfied with this one, which is why it's here. Probably a 3-star effort.
Solution code: Row 6 then Column 6

Tricky start, but cascades nicely once get going.
Good to see it's got red stars now, took a while!

Well, thank you, gentleman, for coming back to this one! I consider it high praise to have three such notables all enjoy it.

I remembered doing this when it came out and breaking it twice. When I saw Richard commented on it, I wondered how this would work if a Chaos component would be thrown in the mix. I ended up constructing this: https://logic-masters.de/Raetselportal/Raetsel/zeigen.php?id=000AWG. So, of course, after having made this, I had to solve the original as well. Quite a lovely flow! Thanks for setting

Cool puzzle! It took me a while to understand the nature of the rules and only then I was able to start it. Thanks a lot for setting this little beauty, Big Tiger! And thanks to Richard for the comment, because otherwise I wouldn't have found it. :)

Very nice one!
Good opening to the puzzle; it took a while before it came into flow. Well done!
