A deductive reasoning puzzle implementing a polyform set of jigsaw-styled puzzle pieces, to be arranged via matching according to constraints set forth in given schematic cards. Best solved through a systematic process of elimination. Serves educational, developmental, and entertainment purposes.

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 two-card sleeve apparatus is described. The two-card sleeve apparatus may include a first transparent layer, an opaque layer, and a second transparent layer. The two-card sleeve apparatus may be used to safely store or display two or more trading cards.

A puzzle assembly system including a puzzle assembly tool having a handle; an illuminator; a powerer; and a magnifier having a body with a front-face; a rear-face; a thickness; and a periphery; wherein the puzzle assembly tool comprises the handle, the illuminator, and the magnifier in functional combination. The illuminator is preferably integral with the handle and powered by the powerer during use. The illuminator is configured to illuminate puzzle pieces for assembly. As designed the magnifier is configured to magnify the puzzle pieces during use (via a magnifying lens) and the puzzle pieces are able to be manipulated via a user moving the body of the magnifier during puzzle-assembly to scoop and place sections or individual puzzle pieces.

A lenticular animation device for animating coded images. A viewing device has a base structure and a pivotally coupled cover structure. A lenticular plate defines a viewing area, and a manually-operated actuation mechanism, such as a crank system, produces longitudinal, reciprocating relative movement between the platen and the lenticular plate. Lateral edge guides maintain alignment. Corresponding alignment formations retained adjacent to the platen and alignment formations in the coded image member cooperate to maintain alignment of the coded image member. Coded images can include user-completed portions, potentially in combination with non-coded images sharing a unified theme, for being colored by a user. Coded images can be exposed by removing an obscuring overlay or applying a reagent or assembled as puzzle pieces to permit user participation in the creation and animation of coded images. Opposed alignment pegs and holes can lock the cover structure against displacement relative to the base structure.

A playing card having a substrate entirely of a first predetermined colour overlaid with a removable surface coating entirely of a second predetermined colour contrasting with said first predetermined colour, said removable surface being sufficiently friable so as to be able to be scratched off by a player in a pattern predetermined by said player to reveal said substrate in said pattern. The scratched playing card uses the high contrasting colors (typically primary and secondary colors) to produce letters or image(s). These cards are interchangeably used in a strategic and non gambling card game often utilising the Stroop effect.

A puzzle building block capable of changing light-emitting areas includes a building block board, a circuit board, light-emitting elements and building bricks. The building block board includes a plate body and connection portions. The connection portions are disposed on the top surface of the plate body. The circuit board is adjacent to the bottom surface of the building block board. The light emitting elements are disposed on the circuit board, and the light emitted from the light emitting elements passes through the building block board via the connection portions. The building bricks are fitted with the connection portions and shield the corresponding connection portions, thereby forming letters or patterns. Therefore, the light emitted from the light-emitting elements can form various letters or patterns on the top surface of the building block board. The present invention also provides a puzzle building block assembly including the above-mentioned puzzle building blocks.

A multi-layer toy having at least one outer layer adjacent a planar layer or a ball where both the outer layer and the adjacent planar layer or ball each contain related information such that, in play, the information on the outer layer is made to align with the related information on the adjacent planar layer or ball. The information can comprise depictions of objects, things, characters, animals, or words, for a matching game, or the information can comprise numbers for a counting or mental math game. The toy is preferably sized to be hand-held.

Described is a board that is operable as a children's book or puzzle with parts that move, slide or turn on one lateral plane to physically change an illustration or part of the item and, as they slide or turn, activate a noise related to the illustration. The board includes a generally planar top illustrative layer. A bottom base layer is attached with the top illustrative layer. The bottom base layer includes a sensor (e.g., light or touch sensor) and sound generation components for generating a sound based upon actuation of the sensor. A moving component is movably connected with the bottom base layer. Finally, the sensor is connected with the bottom base layer and positioned such that moving the moving component from a first position to a second position exposes the sensor to cause the sound generation components to generate a sound.
