Honestly, my favorite game is sudoku. I like it even more than most video games. First of all, it is interesting. I'm working on leveling up. Currently, I'm trying to solve the most difficult sudoku I found here
https://escape-sudoku.com/game/classic-9x9-evil and this is a real challenge for me. Also, sudoku is great for brain training.
Any there any other fans of this game?
