Puzzle Ratings has a post about the 7th 24 Hours Puzzle Championship that takes place anually in Hungary. The contest consists of 13 rounds one after the other, each 100 minutes in length. Factor in a few 5 minute breaks, and that’s 24 straight hours of puzzling. Some may think this sounds like fun, others might think it sounds like torture. But why bring this up for those who don’t live anywhere near Hungary? Glad you asked, the post also has a sample round from last year with some fun puzzles on it. There are the ones you’d expect (sudoku, battleships, etc.) and a few other unusual ones.
