Here is the famous puzzle that started the whole craze. Marketed by Ideal Toy Corporation as "Rubik's Cube," it was originally named "Magic Cube." |

Dozens of variations on Rubik's Cube have been sold. Shown above are a couple with picture stickers instead of solid colors. | |

This is the Rubik's Cube Perpetual Calendar. This very clever arrangement of numbers, letters, and days of the week offers a unique challenge every day of the year! |

Shown at left is a spherical version of the cube. It operates in the same manner, but is a little tricky to align properly when twisting its faces. |
|
Another variant is the Octagonal Barrel, in which four vertical edges of the cube are shaved to create a different shape. When scrambled, it changes shape as the shaved pieces move around. |

On this version, each corner is shaved to create a 14-sided cuboctahedron. |

Eventually, Ideal released Rubik's Revenge, a 4x4x4 version of the original cube concept. The mechanism in these was quite fragile, and for many years they became a valuable collectible. Fortunately they are readily available again today. |
|
The Rubik's Pocket Cube was a 2x2x2 version of the cube for beginners. Shown here is a more recent reissue called Rubik's Mini Cube. |
