This game is an exciting math battle game. The goal of this game is to make the opponents zero-dimensional. You use cards with various operators and functions for the goal. At the beginning of the game, each player has 3 "bases "(1, X, X ^ 2). In your turn, you can perform an operation or add a function to their field from their hands. You can choose between attack or defense. When you choose Attack: Differentiate the opponent's base and erase it. When you choose Defense: Add your own base or strengthen it with integration. The base disappears when the result of the operation becomes 0 or diverges. It seems difficult, but once you learn how to play it, you can always play this exciting game.
