Abstract: A multi-axis rotational puzzle cube has a core unit and multiple first operating assemblies and multiple second operating assemblies rotatably assembled to the core unit. Each one of the multiple first operating assemblies has a first operating unit connected to the core unit, a snap rivet connected to the first operating unit inside the core unit, a blocking tube mounted around and stuck with the snap rivet, and a compression spring mounted around the snap rivet and abutting against the core unit and the blocking tube simultaneously. Each one of the multiple second operating assemblies has a second operating unit connected to the core unit, a snap rivet connected to the second operating unit inside the core unit, a blocking tube mounted around and stuck with the snap rivet, and a compression spring mounted around the snap rivet and abutting against the core unit and the blocking tube simultaneously.

Abstract: An educational ball has a body and multiple operating sets. The body is a square block and has six outer surfaces, six mounting recesses respectively formed in the outer surfaces, and six engaging holes respectively formed through the mounting recesses. The operating sets are connected to the body, are respectively and rotatably mounted in the mounting recesses, and each one of the operating sets has a rotating mount, two covering plates, a sliding groove, and multiple sliding sheets. The rotating mount is rotatably mounted in a corresponding mounting recess, and has an engaging jacket and two inserting holes. The covering plates are connected to the rotating mount, and each covering plate has a connecting pipe, multiple track grooves, and a guiding channel. The sliding sheets are movably mounted in the track grooves of the covering plates and the sliding groove of the operating set to cover the rotating mount.

Abstract: A Ba-Gua game tower includes a main disk and at least one secondary disk attached to the bottom of the main disk. The main disk has a disk body with a top face divided into eight divinatory sections respectively designated with a Chinese character. The secondary disk has a secondary disk body with a top face divided into portions respectively designated with a numeral from 1-6 such that there are multiple sets of numerals on the top face of the secondary disk body. A first ball is able to roll on the top face of the disk body and a second ball is able to roll on the top face of the secondary disk body to respectively indicate where a player should look up in a reference book.

Abstract: A Ba-Gua game disk includes a disk having a flat dice area and a Ba-Gua area surrounding the dice area, a transparent enclosure placed on top of the disk and composed of an outer cover enclosing the Ba-Qua area of the disk and an inner cover integrally formed with the outer cover to enclose the dice area so as to separate the dice area from the Ba-Gua area, a dice movably and rotatably received in the dice area to randomly indicate a numeral from one to six and a ball movably received in the Ba-Gua area to be randomly rested on a corresponding one of the sections such that combination of location of the ball and the numeral of the dice represents a meaning.

Abstract: A game device includes a parallelepiped body having six outer shells engaged on six surfaces. The outer shells each includes a tube engaged with the body and each includes four notches formed in the peripheral portion. A number of slides are slidably engaged in the notches of the outer shells and movable between the notches. Six groups of patterns are printed on the outer surfaces of the slides. The users may move the slides of same group of patterns to the notches of an identical outer shell for educational purposes.

Abstract: A paper folding game includes a sheet of paper divided into twelves squares by a number of folding lines and arranged in a three by four matrix. Four groups of patterns are printed on the upper surfaces and the bottom surfaces of the squares. Six cut lines are arranged in the paper sheet so as to allow the paper sheet to be folded to a cubical shape. The four groups each includes six patterns that may be folded to the six outer surfaces of a cube.
