#13: Tic-Tac-Toe
Tic-tac-toe is a blast when you’re a little kid. As you grow older, it tends to lose its charm. However, someone invented the ultimate tic-tac-toe board using their 3D printer. We have to admit that this creation makes the game look cool again. It’s a bunch of mini-games housed within a jumbo game of tic-tac-toe.
This thing is like its own tic-tac-toe tournament. You can play a series of nine games before moving on to the giant finale. Who will win? Only time and perseverance will tell. We can totally see something like this at a brewery or even a doctor’s office where people want something to pass the time.
