The Ten-Legged Spider (Anchor Sudoku)

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

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.

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!

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.

Increased difficulty to 4 stars

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 :)
