The present invention provides a puzzle comprising: a board that has a plurality of rectangular mounting holes disposed in a lattice form and is formed of a transparent material; at least two pixel blocks including a lower block formed to be larger than the mounting hole and an upper block coupled onto the lower block and inserted into the mounting hole, the upper blocks of which have different heights; and a back board coupled on the rear surface of the board to press and fix the pixel blocks, wherein the board includes: a plurality of cross frames formed in the shape of a cross to separate four adjacent mounting holes; and a cross-shaped rotation frame that is stacked on and coupled to the center of at least one of the cross frames so as to be rotatable and separates the mounting holes. Therefore, the present invention provides an advantageous effect of implementing a three-dimensional design by combining the plurality of pixel blocks, the upper blocks of which have different heights. |
