A two-dimensional jigsaw puzzle including a plurality of pieces, each of the pieces having a main body made of a foam with memory. Each main body has a layer of glue extending thereover and a flexible sheet adhesively bonded thereto. The flexible sheet bears a portion of a picture of the puzzle and the main bodies of the pieces have complementary interlocking joints for detachably assembling the pieces to one another to form the picture of the puzzle. Each of the main bodies has a peripheral side surface with predetermined thickness such that, when the pieces are assembled to one another, the interlocking joints substantially hold the pieces together by friction contact between the peripheral side surfaces of the main bodies. The glue is of a type which remains substantially flexible after setting thereof. As a result of the above-mentioned, the two-dimensional jigsaw puzzle is capable of being bent without any of its pieces detaching themselves from the puzzle.
