A method of gradually revealing an image using cube puzzles is provided. A first image is divided into a plurality of blocks. Each block can have one or more arbitrary colors. A second image is then generated from the first image where each block of the second image corresponds to one or more blocks of the first image. The blocks of the second image are unicolor blocks with colors that are selected from one of the six colors of a cube puzzle. Groups of adjacent blocks of the second image with the same number of rows and columns as the sides of the cube puzzles are assigned to participants to match to the color of the blocks on the sides of their cube puzzles. Once each participant matches the colors of an assigned region on a side of the corresponding cube puzzle, the matched region is reveled to all participants.

The puzzle storage box disclosed herein may comprise an internal locking mechanism designed to challenge ingenuity while being embedded within an assembly of unlimited form potentiality. In one variation, the internal locking mechanism is embedded in a shallow container and may be used for more personal, everyday carry. In another variation, the internal locking mechanism is embedded in a deeper container for increased volume and prominent display. The internal locking mechanism will be incorporated into endless shapes and forms, and its novel method of operation will be respectively conveyed.

A three-dimensional puzzle has a monitoring puzzle piece and multiple monitored puzzle pieces. For puzzle pattern determination, the monitoring puzzle piece is equipped with sensors, a processor, a wireless transceiver, and optionally a gyroscope sensor. The monitored puzzle pieces are rotatably connected to each other and to the monitoring puzzle piece to form the puzzle. The sensors, together with the processor or alternatively with an external client, track the monitored puzzle piece rotating relative to the monitoring puzzle piece. The external client may provide feedback to a user of the puzzle. The system enables the competitions between the user and users of other puzzles without requiring the physical proximity of the competitors.

This invention is a deductive lockpicking puzzle, composed of a clamshell style frame holding a central cylinder that is representative in appearance to that of a normal lock, with a single rectangular keyway in the center. The four locking pins in this device each have two opposing magnetic poles, generated by attached permanent magnets, on either end. Each “lockpick” has a unique pattern of four magnets so that when inserted into the keyway, complementary magnetic poles will attract a pin to the lockpick, generating auditory and tactile feedback to the player upon impact. Once the right lockpick is inserted, all four locking pins are magnetically removed from their resting positions, allowing the central cylinder to rotate ninety degrees to a solved configuration.

A memory puzzle is provided that may include one or more levels of rotatable level housing, a number of puzzle spaces disposed on the rotatable level housings, and a piston for indicating that a portion of the puzzle has been solved, wherein the piston raises to a high level as levels of the puzzle are solved, wherein the puzzle is solved when a code is achieved by rotating the rotatable level housings in a specific pattern.

According to one of aspects, a display device includes: a display unit configured to stereoscopically display an aggregation configured from a plurality of regular hexahedrons arrayed along mutually perpendicular three directions, in a display space, by displaying images respectively corresponding to both eyes of a user by being worn; a detection unit configured to detect movement of a body in the display space; and a control unit configured to change positions of the regular hexahedrons of the aggregation according to a detection result of the detection unit. Each of six faces of the aggregation includes external faces of the regular hexahedrons as elements, and notations with which whether all of the elements on the same face of the aggregation belong to a same group is discriminative are provided to the respective elements.

The Alphacube invention is a collection of modular shapes that form cubes, each letter of the alphabet and that are a twisty cube puzzle that can be solved for each letter of the alphabet. The pieces can both build structures and communicate verbal messages. They are a toy, puzzle, and an educational tool to teach literacy in a fun and engaging way. The pieces can also be assembled into artistic shapes or into basic shapes that describe animals and simple things like a small hole on a flat surface.

A three-dimensional puzzle comprising a plurality of cuboid puzzle blocks together forming a predetermined three-dimensional puzzle shape, wherein each puzzle block comprises either a male or a female connecting element on each of at least three sides of the puzzle block; wherein the connecting elements for the respective puzzle block are configured such that each puzzle block is unique.
