## 3x3x3 Rubik's Cube facts

Here are some 3x3x3 Rubik's cube facts:

- It was first released in 1977.
- There are 4.3*10^19 possible configurations. That's 43,252,003,274,489,856,000 ways a cube can be scrambled. To give you an idea of how big that number is, if there were one cube scrambled for every legal position, they would cover the surface of the earth about 150 times!
- Number of moves to solve
- All positions can be solved using 22 or less moves. Extensive computer analysis is being done to prove this upper bound to be lower, but we know that the lowest it can get is 20 moves, because there are known positions (such as the superflip) that are known to require 20 moves to solve optimally.

## 2x2x2 Cube facts

Here are some 2x2x2 Cube facts:

- There are 3,674,160 positions
