# The Turing Tumble

“Players add logic to the game board by placing six different types of parts onto the board. The ‘Bit’ is a particularly important one. Each time a ball runs over it, it flips to point the opposite direction. Pointing to the left is like a ‘0’, and pointing to the right is like a ‘1.’ Gear bits are the most interesting part, though. Gear bits are just like bits, except that they can be connected to one another so that when one is flipped, it flips the connected gear bits, too. It’s these parts that make the computer Turing-complete,” said Boswell.
