Monsters in town! Can you stop them before they mess up the Mons-Cube Town? Try to re-arrange your Monster Cubes to match the designated Code Number and defeat the monsters! With the help of some mathematics, saving the town is more than fun! In Monster Code mode, players try to solve the puzzle by finding the legal combination of three Monster Cubes that matches the Code number shown on the Monster Card. The player who is the first to announce the correct combination beats the monster and scores the victory points on the Monster Card. Whoever scores the most points in the end wins the game and becomes the hero of Mons-Cube Town!
