Sigma Pi
(Published on 7. December 2023, 21:50 by IcyFruit)
Rules
Normal sudoku rules apply.
Digits around an X sum to 10.
Multiplying the digits on each end of a brown line gives the sum of all digits on that line. For example, a line could have the digits 3-5-4, because 3x4 = 3+5+4.
Solution code: Columns 7 and 9.

I'm with the easier than 5* solvers, but I can quite see how it would get a 5. However it is rated for challenge, it is beautifully constructed.

Cool puzzle, thanks!

Nice new ruleset, but I'm surprised this is rated 5 difficulty - only 3 for me.

This flowed so well, and forced me to do a lot of mental math to determine possibilities in two specific areas. Loved this ruleset.

Another new constraint with some beautiful logic throughout. Really enjoyed this challenge. Well done IcyFruit and thank you for creating this gem.

Another spectacular puzzle! I find this quite approachable though, or at least not mind-binding.

This was stellar. Really enjoyed working out all the moving parts.

Great concept but it wasnt that hard. Probably 3.5*

There're a few times I looked at some random line and then I was like "how were they drawn like this", and it was only a short while later that I was in awe of the hidden logic in there. Another unexpectedly clever puzzle as usual! ;)

Great puzzle! Very nice flow of deductions.
I guess I was perfectly prepared for this ruleset after setting my puzzle "Factor Finesse" :-)
26 min is usually not what I can expect when I attempt a 5/5 difficulty.
