A jigsaw puzzle kit is provided having a plurality of interlocking puzzle pieces configured for assembly to form a three dimensional image, each puzzle piece having a surface an image applied thereon, a resilient layer for generating a tactile response when the puzzle piece is depressed, and a rigid backing layer below the resilient layer for providing support. Also provided is a method of manufacturing a jigsaw puzzle which includes the steps of applying an image onto the surface of a resilient material; applying a mold to the resilient material so as to create variations in the height of the resilient layer; adhering a rigid backing material to the molded resilient material; and die cutting the resilient material and the rigid backing material to create a plurality of interlocking puzzle pieces.

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 bottle puzzle used as a training or learning tool for children and adults with cognitive disabilities has puzzle pieces with uniquely shaped concave and convex walls, with only one wall in one puzzle piece matching another wall in a different puzzle piece. Each puzzle piece is a fully contained compartment capable of holding and dispensing beverages. When puzzles are put together, they form a normal bottle that can be filled with beverages contained in the puzzle pieces. A mixing chamber allows consuming several beverages contained in the puzzle pieces simultaneously.

A three-dimensional logic puzzle is provided. The puzzle includes a plurality of identically shaped puzzle components of an irregular form. Each puzzle component is configured to engage with another identically shaped puzzle component via projections and recesses formed on the sides of the puzzle components. The plurality of puzzle components are interengagably assembled into the form of a predetermined three-dimensional geometric shape.
