The present application discloses a domino structure system comprising a track, a plurality of rods, a plurality of dominoes, a plurality of stoppers and at least one stand. The track comprises a left rail and a right rail. Each of the rods is coupled to the left rail at rate end and to the right ail at another end. The plurality of dominoes is rotatably coupled to the plurality of rods. The plurality of stoppers is capable of stopping the plurality of dominoes when the plurality of dominoes is perpendicular to the track. The at least one stand comprises a base, a column and a supporter, the column is coupled to the base, the supporter is coupled to the column, wherein the supporter is capable of supporting the track. A domino structure is also disclosed.

Provided is a toy building system. The toy building system may comprise one or more of interconnecting tiles, flat tiles, arcs, line reactors, clips, tracks, rotatable tracks, split tracks, launchers and other pieces that are adaptable to connect in a multitude of configurations and may be set up in sequence to create a chain reaction of falling as in dominos. Various types of tiles or falling units may be utilized, including line reactors, arcs, or tiles having a multitude of different mating components and orientations including an interconnecting orientation and a flat orientation. The domino tile may further connect to other pieces of the toy building system including an arc or a rapid track builders including a track and a clip. The tiles, independently set up, as a part of the arc, or as a part of the rapid track and/or line reactors may be positioned so as to create a domino effect when a force is applied thereto, such as a force applied by a launcher. The various components and interconnectability between components allow for limitless configurations as building blocks and as a domino show.

A swaying toy includes: a grounding-position-variable base member; a tubular tower member erected from the base member; a ball placing member which allows a ball to be placed thereon; and a piece placing member including a piece placing portion which allows a piece to be placed thereon and a ball-hit portion to be hit by the ball. The piece placing member is swingably attached to the tower member. The ball is released from the ball placing member according to a grounding state of the base member and passes through an inside space of the tower member.
