Tenbillion

The Tenbillion was a toy Nintendo released in 1980 in Japan for 1,000 yen. Resembling a miniature barrel, this cylinder-shaped object features six separate levels, 23 colored balls and three black balls. The goal of the game is to make sure balls of the same color are placed on the same level, which proved to be quite a challenge. Gunpei Yokoi, who created the game, named it after the fact that there are billions of different ways to complete the game.
