Can you crack Killer Sudoku’s mathematical twist?
I’ve been enjoying Scientific American’s sudokus a lot this year. They follow an almost-daily schedule throughout the weekdays:
- Monday is an Easy one
- Tuesday a Medium
- Wednesday is Hard
- Thursday is “Expert”
- Friday is Killer Sudoku
Hope y’all enjoy!

I’ll try this on Monday :)
You completed the puzzle in 21 minutes and 50 seconds.That was fun, thanks. I didn’t see an option to share results, did I miss it?
This is brutal. I know a lot of the tricks here but this is just nasty.
