The present disclosure discloses a tornado yoyo, including two rotating disks and a connecting axle configured to connect back portions of the two rotating disks, in which a protruding cylinder provided with a bearing thereon is disposed in the rotating disk and located in the middle of the rotating disk; a rotating cap is disposed outside the rotating disk and provided with a connecting hole portion extending from the middle of the rotating cap to the rotating disk, and the connecting hole portion is sleeved on the bearing to realize a rotation of the rotating cap relative to the rotating disk; and an outer edge of the rotating cap is provided with an edgefold configured to envelop an edge of the rotating disk, so that when the yo-yo is held or pinched in a forward direction, the rotation of the rotating disk will not be influenced.

An adjustable counterweight for a yo-yo allows for the addition or subtraction of weight plates in a midsection of the counterweight assembly. The counterweight includes a first portion having at least one post, a second portion having at least one post, at least one weight plate having at least one aperture, and a bore that extends through the first portion and the second portion, and is configured to receive a fastener. The at least one weight plate is disposed between the first portion and the second portion.

A yo-yo has at least one sensor configured to measure a parameter related to movement of the yo-yo, a transmitter configured to transmit the measured parameter to the computing device. A server is configured to determine a trick performed with the yo-yo based on the measured parameter, and to communicate the determination to one or more computing devices of different players.

A spinning toy is housed within a handle-shaped housing and a string actuated internal spinning mechanism. The internal spinning mechanism is secured to a vertical shaft which projects from the top of the housing. Secured to the distal exterior end of the shaft is a propeller comprising a plurality of blades. An exterior end of the string projects through the housing. When the string is pulled it actuates the spinning mechanism which actuates the vertical shaft which in turn rotates the propeller.

A spinning toy including a base, at least one shaft coupled to the base, and at least one winged object having a hub and a series of wings coupled to the hub. The hub of the winged object is rotatably mountable on the shaft. When the hub is rotatably mounted on the shaft and rotated relative to the shaft, the winged object is configured to move along the shaft toward the base.
