Abstract
Planar puzzles and a game utilizing these puzzles exploit simple geometric shapes for the design of a plurality of initial configurations that make up each of the puzzles. Each of the initial configurations may be further subdivided into elementary pieceparts. For each puzzle, it is possible to rearrange certain of the initial configurations to form a new puzzle configuration having the identical shape of the initial configurations by reassembling the pieceparts of each of the configurations. By proceeding in a series of merger steps, it is possible to rearrange all of the initial configurations into a single merged configuration that also has the same shape as the original configurations. The game aspect furnishes each player with the opportunity to generate mergers from configurations under control of the other players. The strategy is to generate as many mergers as possible in the time allowed while blocking other players from merger opportunities.
