The jigsaw puzzle includes a baseplate used with attachable puzzle pieces. The baseplate has multiple upward-facing engagement mechanisms that are engaged with corresponding and complementary puzzle piece rear-facing engagement mechanisms. The rear-facing engagement mechanisms and the complementary puzzle piece rear-facing engagement mechanisms are designed so as to leave a space between the bottom of the puzzle piece and the top surface of the baseplate to facilitate removal of the puzzle pieces. An optional pry tool can be inserted in to the space to easily remove the puzzle pieces after play, storage, or display. An optional hanger/joiner can be utilized to hang the completed puzzle vertically and/or to join two baseplates to create increased play opportunities.

The invention relates to a modular ball track system, comprising the following: a plurality of module elements (12; 12), the exterior shape of all of which is the same regular polygon in plan view and each of which hasan upper face (14), a lower face (16) opposite the upper face, anda number of lateral surfaces (18), said number corresponding to the number of corners of said module element, wherein each module element (12; 12) forms at least one section (20, 22) of a ball track on the upper face (14) of the module element, said section passing through a lateral surface (18) of the module element, and a plug socket (24) protrudes from each module element (12; 12) on the lower face (16) of the module element, anda base (32) with a plurality of uniformly arranged recesses (34) for receiving a respective plug socket (24), wherein the plurality of recesses (34) are arranged on the base (32) in a grid, the size (s) of the grid corresponds to the incircle diameter of the regular polygon which forms the exterior shape of the module element, and module elements (12; 12) plugged into directly adjacently lying recesses (34) of the base (32) abut one another in a flush manner at a respective lateral surface (18).

The jigsaw puzzle includes a baseplate used with attachable puzzle pieces. The baseplate has multiple upward-facing engagement mechanisms that are engaged with corresponding and complementary puzzle piece rear-facing engagement mechanisms. The rear-facing engagement mechanisms and the complementary puzzle piece rear-facing engagement mechanisms are designed so as to leave an access space between the bottom of the puzzle piece and the top surface of the baseplate to facilitate removal of the puzzle pieces. A prying object (pry tool, user's fingertip, toy, or the like) can be inserted in to the access space to easily remove the puzzle pieces after play, storage, or display.
