A child play puzzle includes a set of pieces each defining a non-circular aperture therethrough. The child play puzzle also includes a base and a pole extending from the base along a pole axis. The pole sequentially receives each piece of the set of pieces with the pole extending through the aperture of each piece to form a stack of the pieces along the pole. The pole has multiple sections spaced along its length. Each section is of non-circular cross-section in a plane perpendicular to the pole axis. At least one of the sections is rotatable about the pole axis with respect to an adjacent one of the sections, such that moving a piece from about the rotatable section to about the adjacent section requires rotationally aligning the rotatable section with the adjacent section.

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.

A playground equipment comprising an array structure of networked ropes arranged in a rectangular array of parallelly arranged first ropes and intersecting second ropes and one or more rolls connected to a first rope, between two neighbouring second ropes wherein each roll comprises an inner clamping part configured for non-slideable fixation to the respective first rope, and an outer part attachable to the inner clamping part
wherein the inner clamping part and the outer part are in non-slideable connection relative to each other and wherein the outer part is rotatable relative to the inner clamping part.

A multi-surfaced gear-based mechanical puzzle where the objective is to choose the proper sized gear and position on the surface(s) from available holes to have the gears align and rotate in unison on one or multiple surfaces, flat or curved, from a dictated start point to a dictated finish point.

Challenges such as going from “a” point to “c” point directly or additionally through way point “c” are outlined in an accompanying instruction booklet. Additionally, challenges may be presented as using a specific number or specific size of gears, for example, to achieve the objective.

In achieving the right combination of gear sizes and positions, the objective of going from one start point to a finish point by turning one gear to cause all other gears in the train to turn in unison can be accomplished.

The puzzle and components may be made from wood, plastic, metal or a composite material.

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.

Games and toys that include systems, devices, apparatus and methods for physically and mechanically organizing a plurality of separate pentagon face pieces in combination with a plurality of separate triangular face pieces to form icosidodecahedron with one of several predetermined patterns. The games and toys can include a 2-color and 4-color setups of using 12 pentagon face pieces with 20 triangular face pieces, each of the pieces can include magnets on their bottom which magnetically attract to central metal bearing forming an overall sphere shape. Sections of the assembled icosidodecahedron can be rotated along up to six equators by the player into different predetermined patterns that exist from the two color and four-color setups.

A 3-D magnetic puzzle is implemented as sphere consisting of movable sectors configured to move about a center piece. The movable sectors are configured to host movable elements configured to change a state of the 3-D magnetic puzzle, wherein: the Movable sectors are configured to change their positioning relative to each other; and the movable sectors include sphere segments with cavities configured to accommodate the movable elements comprising permanent magnets. Each of the movable elements is configured to move inside the cavity responsive to a magnetic field provided by the permanent magnets responsive to the movable sectors change their positioning relative to each other.
