Fire is weak to water, but strong against snow. Water is weak to snow, but strong against fire. Snow is weak to fire, strong against water. Whenever a player uses a stronger card against the opponent, they will get a card of the same color and element added to their score on their side of the screen. If two players use the same element, the card with the higher number is the one chosen to add to a player's score. If two players use the same element with the same number, a draw will happen resulting in another card having to be played by both players. There is a special type of card, called a Power Card. When played correctly, they could have effects such as reversing card priority, removing points from the opponent, or adding points to the player that played the card. These types of cards also have unique animations compared to the other cards.
