Abstract
An interlocking three-dimensional solid puzzle having component pieces that can be interlocked into an assembled configuration without any significant internal voids. The component pieces include sliding control mechanisms to control movement of the pieces and are preferably structured such that specific movement of one or more pieces is required before any piece can be removed. The sliding control mechanism preferably includes an array of mating projecting studs and channels on the individual puzzle pieces that cooperate to selectively limit movement of the pieces, and or provide false moves that do not advance assembly and/or disassembly. The present invention provides a new class of interlocking solid puzzles characterized as being challenging to assemble and disassemble while having a lower piece count than comparable existing puzzles.
