Not Puzzle the Donkey
Solve a Puzzle Day sounds like it could be a lot of fun. You get to pick any type of puzzle and attempt to puzzle it out.
You can choose a jigsaw puzzle, a crossword puzzle, a word puzzle, a logic puzzle, a physical metal puzzle, or any other you can find.
You probably won't have to buy anything to find a puzzle to solve, but you can if you want to.
You can work on the puzzle with one or more friends. In fact, puzzles are often more fun to do that way.
The difficulty level of the puzzle you choose doesn't really matter. If you feel up to a greater challenge, then go for a tough nut to crack.
If you feel like a wimp, try something easy that even a child could do.
You don't have to finish solving the puzzle today. You only have to start working on it.
Merry Christmas.
