Normal sudoku rules apply.
Digits in column 1 indicate the column in which the digit 1 appears in that row (e.g. if r4c1 is a 6, r4c6 is a 1). The same applies to columns 5 and 9, with the digits 5 and 9 respectively. The same also applies to rows 1, 5, and 9 (e.g. if r5c7 is a 3, r3c7 is a 5).
Note: This is the first puzzle I've published here, so please be honest with feedback; if this is too easy, or boring, please let me know. I would really appreciate criticism!

After practicing on a series of 159s I found this one quite approachable. It is amazing how so little initial input is needed. Thanks!

This was quite an enjoyable solve! I definitely got turned around a few times, but a really gratifying puzzle. Thanks for making it!

I love 159s, but they are already quite mind benders sometimes. This takes it to another level, but still liked it a lot.
I just dread the day when someone comes out with this rule set but with a 4/5 or 5/5 difficulty. My head will explode.
