A "Pokémon" trading card game also exists. Players use Pokémon cards to battle each other and collect them by opening packs. There are also live tournaments hosted by Nintendo. Pokémon's damage is counted by "damage counters" or objects which are placed on the cards to keep track of damage. After you add up all of the numbers on the damage counters, you subtract it from the card's HP (health points) to find out how much HP is left. Only 60 cards are used in a player's deck, and six of these are set aside in a pile called "prize cards." After one player knocks out an opponent's card, the defeater takes just one face-down prize card for non-EX Pokémon. Meanwhile, when someone makes an EX Pokémon faint, he or she gets two prize cards. There is one discard pile for each player, where fainted Pokémon go. Some ways to win are taking all of your prize cards, and/or making your opponent draw all of his or her cards.
