Millennium Game is a Yu-Gi-Oh! board game created by Mattel in 2002. It features action figures of Mai Valentine, Yami Yugi, Joey Wheeler, and Seto Kaiba. In order to become the "King of Games", players must obtain all five pieces of the 3D Millennium Puzzle. Each player begins the game in the Ultimate Dueling Arena with one piece of the puzzle. Players need powerful monsters to win the "Arena" duels, and gather them by visiting the "Game Shops" located at the four corners of the board. Players move between the Arena and the Game Shops, battling in three separate duels along the way - Janken, Saikoro and Ikusa - trying to get the most powerful Monster Slider Cards. They return to the Arena to compete for the remaining puzzle pieces. The first player to assemble the Millennium Puzzle wins.
