Introducing Anchor Sudoku!

Introducing Anchor Sudoku!

I have recently been playing around with a new constraint I am calling anchor sudoku. It is like arrow sudoku, except you subtract the smallest digit from the sum of the other digits.

So for example an anchor with a 5 in the square, and 4,2,3 in the chain would be valid because 5=4+3-2. Repeat digits are allowed so 5,5,1,1 would also be valid because 5=5+1-1.

If this variant already has a name please let me know and I will rename it!

Over the past few weeks I have made seven puzzles using this variant, and I have been really surprised by their versatility. I am planning to release one puzzle every day for the next week which will hopefully showcase some of its potential.

This first puzzle is intended to introduce some of the restrictions caused by anchors before doing some more clever things with them.

Rules

Standard sudoku rules apply.

Subtracting the smallest number along an anchor from the sum of the other numbers equals the number in the square cell.

Well, I gave it a shot. Took a while to find a break in, then about an hour later I had messed up somewhere (and could not see how to fix it). I think there are just too many possibilities to wrap my head around. Very interesting though.

I am looking forward to trying this. I think Anchor is a fine name. What does "killer" have to do with "Killer cages" or "Little killer"? So, why does "anchor" need to have some "sea" reference?

Menu Sudoku??
The cheapest item on the menu gets subtracted from the total bill

I just feel the naming of this variant is a little weak. Afterall, it's a subtract arrow. The naming should show the idea of subtract. Also anchor is the name that every setter at one point think of. It's just not a memorable variant name for me.

@bigger

Good suggestion, I will only post one every few days.

As for naming, I am open to suggestions. I wanted to pick a real life object that has a line attached to it. I was considering calling them tails, anchors, keys, plugs, or circuits.

Think I should go with a different one?

Nice variant. But I should warn you that posting one puzzle per day for a week is a bad idea. It's going to flood this portal. Maybe per two or three days.
Also I have a small question, why it's called anchor? I see no ships nor seas.

Very interesting new idea!
Tougher than I thought, needed new ways of logic
