I first think of one of my favorite games, Sudoku. I really enjoy that puzzle game. In fact I carry a book of Sudoku games in my Jeep in case I have to spend time waiting on my wife while she shops at Michael's or Hobby Lobby of if I have to wait for service at a doctor's office or auto repair shop or where ever I have to wait for someone or something. Do you want some examples? If so, there are a lot of sites on the internet with Sudoku games. Here is one of them:
If you try them or have worked Sudoku puzzles before, let me know how you like them. I guess you could say they are sort of a numbers crossword or crossnumbers puzzle. Yes, I know that "crossnumbers" is not a real word but this is my blog and I will use it if I want to (grin). I hope you don't lose any sleep nor pull any of your hair out trying to figure them out, but have a great day, you hear?
