Abstract: 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.
