Ultimagear plastic model kits lets users experience putting together realistic items featured in popular anime, manga, and movies while enjoying their structures, gimmicks, and textures. The first round features the global fan-favorite Millennium Puzzle from the Yu-Gi-Oh! series! Ultimagear Millennium Puzzle has steps in its build. Step 1 is to assemble the puzzle pieces, and step 2 is to complete the Millennium Puzzle as a puzzle. There are no instructions to complete the assembly from step 2 for this unprecedented plastic model kit. In order to complete this puzzle, one must rely on their "intuition" to find a very small path to completion from the "countless assembly patterns" that are created from the order, positioning, sliding and spinning of the pieces. The completed kit is approx. 3.93" (10 cm) long, recreating the size of the actual puzzle.
