A cylindrical jigsaw puzzle comprising:
- a bottom rim having an outer flange, an inner flange integrally formed with the outer flange and a first gap defined between the outer flange and the inner flange;
- a top rim having a ring body, a positioning flange extending from an inner face of the ring body and a second gap defined between the ring body and the positioning flange;
- top puzzle pieces each having a first assembly edge corresponding to and received in the second gap of the top rim, a first step formed on a face adjacent to the assembly edge to abut a peripheral edge of the ring body, two connection arms respectively extending from two opposed sides of the top puzzle piece and a cutout defined in a side face opposed to the side face where the assembly edge is formed to be complementary to the connection arm;
- and
- bottom puzzle pieces each having a second assembly edge (131) corresponding to and received in the first gap (23) of the bottom rim (2), a second step (132) formed on a face adjacent to the second assembly edge (131) to abut a peripheral edge of the outer flange (21), two connection arms (133) respectively extending from two opposed sides of the bottom puzzle piece (13) and a cutout (134) defined in a side face opposed to the side face where the second assembly edge (132) is formed to be complementary to the connection arm of the bottom puzzle piece (13).
