A short while ago I purchased a Sudoku board. Yes, an actual wooden board upon which to play that usually pen-and-paper numbers game.
It might be the coolest thing ever.
It came with full sized number tiles, double sided, with red numbers for your starting numbers on one side, and black numbers for where you’re “writing” your solution on the other sides.
It even came with 1/4 size number tiles (not pictured), so that you can put guesses in squares as you process the solution.
Best $24 I’ve spent this year? Absolutely.
