A dart pistol utilizes an assembly of a pistol body, a launch channel, a carriage, a mainspring, an operating bar, an engagement feature, a trigger member, and a retainer pin to adapt a conventional game of throwing darts into a shooting sport. The launch channel is formed into the pistol body such that the carriage, mainspring, and operating bar are slidably mounted between a fore body end and a rear body end. The mainspring is connected between the carriage and the fore body end to impart a launching force to at least one projectile via the carriage. The retainer pin is laterally mounted into the channel to capture the engagement feature of the operating bar until dislodged by the trigger member. The trigger member is pivotably mounted to the pistol body, operatively coupling the trigger member to the operating bar to fire the dart pistol.

A dice rolling device (1) includes a housing (12) formed in a bottomed tubular shape that opens upward, and a plurality of pins {first and second pins (22, 24)} provided in the bottom portion of the housing (12). Further, the dice rolling device (1) includes a flat plate portion (8) with a plurality of through holes (9) through which the pins are inserted, and includes a dice stage (4) accommodated in the housing (12) movably in the vertical direction. The dice rolling device (1) further includes a spring member (31) that biases the dice stage (4) upward, a dome-shaped cover (2) that covers the flat plate portion (8) from above, and a die accommodated in a space (S1) surrounded by the cover (2) and the dice stage (4). The moving range of the dice stage (4) is the range between the lower limit position in which the pins (22, 24) extend through the through holes (9) and protrude above the flat plate portion (8) and the upper limit position in which the pins are accommodated in the through holes (9).

Hence, this invention can provide the dice rolling device (1) having high contingency of appearing dots of a die.

An article is moveable between a first position and a second position and biased to the second position. The article is retained in the first position by retaining means until a predetermined condition is met and when met, the biasing means are released to move the article from the first position to the second position. The predetermined condition is met when at least one formation of a plurality of formations located with respect to at least one face of the article is moved from a first position to a second position, thereby releasing the retaining means. The article further includes user selection means to allow the user to select which one, or combination, of the plurality of formations, when moved, will cause the release of the retaining means.

A building and demolition game apparatus includes a base, a plurality of rectangular block elements, a monitoring unit, a game control unit and a force generating unit. The base has an assembly platform located on an upside of the base. The rectangular block elements layered to form a tower, which is stood on the assembly platform. The tower has upper and lower layers held by frictional coupling between the layers. The tower height increases during game play by removing block elements from one or more lower layers to build up successive upper layers upon the assembly platform. The monitoring unit is disposed in the base to obtain at least two boundary conditions by continuously monitoring. The game control unit is disposed in the base to generate a control signal according to a predetermined threshold and the at least two boundary conditions. The force generating unit is disposed in the base and under the assembly platform. The force generating unit is applying a force forward to the assembly platform according to the control signal generated by the game control unit.

A magic cube with visible magnetic cabins includes a central shaft piece, six central blocks, eight corner blocks, and twelve edge blocks. Corner block magnetic cabins and edge block magnetic cabins are respectively arranged on the corner blocks and the edge blocks. Magnets and magnetic pieces are respectively arranged in the corner block magnetic cabins and the edge block magnetic cabins. Elastic force between the central blocks and the central shaft piece is adjusted by gear adjusting pieces arranged in the central blocks. By arranging the corner block and edge block magnetic cabins, stability of installation positions of the magnets and magnetic pieces is ensured and an assembly accuracy is improved. The magnetic pieces do not fall off or offset during use. By arranging the gear adjusting pieces in the central blocks, it is convenient to quickly adjust elastic force between the central blocks and the central shaft piece.

The disclosure provides an educational toy. The educational toy incudes a base, a rotatable frame, at least one clamping claw, and at least one impact device. The base is configured for placing on an external placement surface. The rotatable frame is provided on the base and is capable of being rotated on the base when driven by external force. The at least one clamping claw is located on the rotatable frame and configured for clamping a gift. The at least one impact device is arranged on a peripheral side of the base and configured for impacting the gift on the clamp claw when driven by external force.

The article further includes user selection means to allow the user to select which one, or combination, of the plurality of formations, when moved, will cause the release of the retaining means.

A card collection may include a box-shaped card storing portion having an open top, in which the collected cards are stacked. The the card storing portion may include a front portion configuring, a rear portion configuring, two side portions, and a plate-shaped placement board having a placement surface on which the cards are to be placed. The placement surface is inclined upward toward a front side. A rear end of the placement board is connected to the rear portion, a front end of the placement board is separated from the front portion and at least front portions at the left and right ends of the placement board are separated from the side portions, and the placement board, the front side of which moves in the top-bottom direction, can be elastically deformed.
