Yoyo is a game composed of two equal-sized discs (usually made of plastic, wood, or metal) connected to an axis, where the rolled rope is used. One end of the rope is attached to the axis, while the other end is free and is usually linked. The yo-yo game is one of the most popular games in many parts of the world. Although generally considered a children's game, not a few adults who have professional skills in playing yo-yo.
Yoyo is played by hooking the free end of the rope around the middle finger, holding the yo-yo, and throwing it down with a smooth movement. As the straps stretch out on the axis, a gyroscopic effect will occur, which gives time to perform some movement. By moving the wrist, yoyo can be returned to the player's hand, where the rope will re-roll in the axis gap.
