Abstract: A method of gradually revealing an image using cube puzzles is provided. A first image is divided into a plurality of blocks. Each block can have one or more arbitrary colors. A second image is then generated from the first image where each block of the second image corresponds to one or more blocks of the first image. The blocks of the second image are unicolor blocks with colors that are selected from one of the six colors of a cube puzzle. Groups of adjacent blocks of the second image with the same number of rows and columns as the sides of the cube puzzles are assigned to participants to match to the color of the blocks on the sides of their cube puzzles. Once each participant matches the colors of an assigned region on a side of the corresponding cube puzzle, the matched region is reveled to all participants.
