The Ten-Legged Spider (Anchor Sudoku)

(Published on 10. June 2021, 15:28 by FryTheGuy)

The Ten-Legged Spider

(actually it is a solifugae)

This is the second puzzle in a series of seven anchor sudoku puzzles.

Anchors are like arrows, 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.

Previous Puzzles
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.

@Piatato

Happy to hear you liked it! I tried to make the solving path as different as possible across all 7 puzzles, hopefully you keep finding them interesting.

Again, a very interesting puzzle with this new constraint. I'm glad I got to practise this a bit in your previous puzzle! Looking forward to see what else you've got in store!

@polar

I am really glad you solved it. I underestimated the difficulty because I have already internalized a lot of the "obvious" deductions with anchors. In retrospect this probably was not the best choice for the second puzzle with the rule set.

Lovely puzzle! Probably closer to a 3.5/4* for me, as I found it very easy to make mistakes and the rules aren't so intuitive (yet). Look forward to the next ones :)
