Yo-yo is a toy which is an object consisting of an axle attached to two disks, and with a length of string looped around the axle, like a slender spool. Yo-yo is played by holding the free end of the string (handle) enabling the force of a throw or gravity to spin the yo-yo and unwind the string and then allowing it to wind itself back to the player's hand, exploiting its spin. This whole trick is usually called "yo-yoing". A yo-yo competition usually includes two parts, a set of compulsory tricks and freestyle in which the points are scored for each and the winner is the one who scores the most points. There are six divisions in which one can compete- 1A, 2A, 3A, 4A, 5A and AP. The game was first made famous in the 1920s and remains a popular pastime of many generations and cultures. Yo-yo was known in ancient Greece but is mostly associated with Japanese culture as it is very popular in Japan. The name "yo-yo" was registered first in 1932 by Sam Dubiner in Vancouver, Canada as a trademark and the first World Yo-Yo Contest in London, England was won by Harvey Lowe in 1932 and is held every year since then.
The first yoyo manufacturing company was created in 1928 by a Filipino immigrant named Pedro Flores. It was located in Santa Barbara, California.
The name Yoyo was trademarked in 1932 by Sam Dubiner. The first yoyo world championship was conducted in London and won by Harvey Lowe.
The modern design of ball bearing yoyos was introduced in 1990 by Tom Kuhn, a world famous yoyo designer.
The main difference between the initial design of yoyos and their more common - modern - design is the way they are spun. The contemporary design of spinning yoyos provided increased stability and sophistication of yoyos.
The Chinese yoyo or diabolo is a variant of yoyo that includes two cups conjoined in an hourglass shape. This type of Yoyo is spun using a string attached to two hand sticks known as wands.
It is mainly used as a circus prop.
Eskimo yo-yoAn Eskimo yoyo is a traditional two-balled bolas-like fur-covered padded poi type yo-yo played by the natives of Alaska.,
A Paper yo-yo is solely made of a stick and a long roll of paper. When the stick is flicked by hand, the roll of paper extends outwards. When the stick is brought upright (or sometimes merely on its own), the paper compacts again.
It is the only equipment used in the sport. It is a wheel like small object that consists of a shaft connected to two disks. A string is looped around the shaft and its free end is used to hold and play.
