A mechanical lock box comprising a housing including a lid and a hook fastener attached to the lid and a 3D multi-level printed maze. A release chamber is located within the maze and a ball is enclosed in the maze. The mechanical lock box further includes a hook bar having a first hook bar end which pivotally connects to a pivot box in the maze and a second hook bar end having a lock hook configured to engage with the hook fastener to hold the lid in a locked position. A hook pusher is configured to pivot the hook bar to unlock the lid when the ball pushes against the hook pusher.

A piece of three-dimensional maze, wherein at least two of six faces of a cube have opening faces such that a path connecting the opening faces of two faces is defined by flat plate of the cube.

A space puzzle including a plurality of outer face panels, at least two of the plurality of outer face panels each defining at least one path segment. Each of the outer face panels is rotatable, and the rotation of any one of the outer face panels is independent of and not altering any path segment defined in another of the outer face panels. The path segments on the at least two of the outer face panels of the puzzle are configured such that at least one sequence of rotations of at least one of the at least two of the outer face panels exists that permits a position indicator to travel along a continuous pathway between a preset starting point and a preset finish point along the at least one path segment of the at least two of the plurality of outer face panels.

A maze capable of changing rolling paths contains: a rotatable three-dimensional block formed in a six-sided cube shape and defined by twenty-six square cube units for matching with a central fixing element. The rotatable three-dimensional block includes nine of the twenty-six square cube units formed in a 3 by 3 grid arranged on the rotatable three-dimensional block, and each square cube unit has three sets of rotary layers so as to form twelve rotary layer units. The rotatable three-dimensional block includes at least one path having at least one visible window formed on the at least one path respectively. The at least one path is formed in any one of a T shape, a cross shape, and an arc shape on each square cube unit, and the at least one path includes a ball rolling therein and at least one channel which communicates with one another.

A space puzzle including a plurality of outer face panels, at least two of the plurality of outer face panels each defining at least one path segment. Each of the outer face panels is rotatable, and the rotation of any one of the outer face panels is independent of and not altering any path segment defined in another of the outer face panels. The path segments on the at least two of the outer face panels of the puzzle are configured such that at least one sequence of rotations of at least one of the at least two of the outer face panels exists that permits a position indicator to travel along a continuous pathway between a preset starting point and a preset finish point along the at least one path segment of the at least two of the plurality of outer face panels.

A three-dimensional maze structure contains: at least one body and at least one ball. Each body includes a central shaft, multiple partitions, and multiple paths. Each path is defined between any two adjacent partitions, among each path and any two adjacent partitions is formed a trapezoidal oblique surface, and each partitions is distributed by multiple semi-trapezoidal stop pieces, the stop piece has two peripheral ribs horizontally extending outward from two sides of each path to prevent the ball rolling out respectively, and between two facing peripheral ribs of any two adjacent stop pieces is defined a window. Each path has multiple fences and plural passages arranged in an irregular manner. Each ball rolls in each path of each body and a point with the trapezoidal oblique surface, hence each ball rolls and is stopped by the stop piece and then moves through horizontal path of any two adjacent partitions.

Embodiments of the present invention are directed to a three-dimensional game. In some embodiments, the three-dimensional game is a maze game where a player maneuvers at least one ball around tracks and barriers disposed within an enclosure. The player is able to select which track they would like to attempt, and then work with gravity and carefully shift, flip, turn and twist the enclosure to guide the ball. In some embodiments, the enclosure includes a first portion and a second portion. A handle is externally coupled to each portion of the enclosure to manipulate parts of the three-dimensional game to create new pathways, to align pathways enabling completion, or both. A current game state can be preserved by resting the three-dimensional game on a pedestal configured to receive the enclosure.
