The Nintendo tumbler puzzle, also known as the Ten Billion Barrel in English and originally tenbirion (テンビリオン?) in Japanese, is a mathematical puzzle in the style of Rubik's Cube. It was invented by Gunpei Yokoi of Nintendo in 1980 and is covered by U.S. Patent 4,376,537.
It consists of a "cylinder" of transparent plastic divided into six levels, together with a black plastic "frame". The frame consists of upper and lower discs that are joined together through the middle of the cylinder.
The top and bottom levels of the cylinder form a single piece, but between them are two rotatable pieces each two levels high. Each of the four central levels is divided into five chambers each containing a coloured ball. The top and bottom levels have only three chambers, containing either three balls or three parts of the frame depending on the relative position of frame and cylinder.
The balls in three of the five resulting columns of chambers can be moved up or down one level by raising or lowering the frame relative to the transparent cylinder.
The object is to sort the balls, so that each of the five columns contains balls of a single colour.
As a tribute to the deceased creator of the puzzle and former Metroid series director, Gunpei Yokoi, the puzzle made a small cameo appearance in Metroid Prime for GameCube, Samus Aran would have to use her morph ball form and charges to interact with it, once completed would allow her spider form morph ball entrance to a higher level of the chamber.
The puzzle appears in Animal Crossing: New Leaf as well. It is one of the prizes you can get from Redd during August when the fireworks are on.
