Dad did it! A 5 Star Sudoku solved completely in my head without ANY writing of numbers or notations. Didn't think it was possible, but here's proof to give me a few extra months before my teenage boys think they're smarter than me.
It's a two part challenge. First is solving every square only in your head w/o a single note, and second is remembering around 55 different numbers and their locations. Great brain exercise if it doesn't drive you crazy first!
