The Pokémon Trading Card Game (ポケモンカードゲーム, Pokemon Kādo Gēmu, "Pokémon Card Game"), abbreviated as PTCG or Pokémon TCG, is a collectible card game developed by Creatures Inc. based on the Pokémon franchise. Standard gameplay cards include Pokémon cards, energy cards, trainer cards, and stadium cards, a variant of trainer cards. Pokémon cards contain data about the creature's type,and where it came from, attacks, ability, and HP as well as any special effects the cards have on the game.

Pokémon card collectables are valued based on their rarity, though some lower rarity cards can be worth more than higher rarity ones. This depends on the popularity of the card within competitive play, the age of the card, number of cards printed, and various other factors. From the lowest to the highest level, cards rarities are indicated by different shapes on the bottom corner, i.e. Common (circle), Uncommon (diamond), and Rare (star). Japanese-edition cards use letters rather than shapes to denote rarities; i.e. from the lowest to the highest level, C, U, R, RR, SR, and UR. In a single Pokémon TCG booster pack, a collector can pull 10 cards in total, i.e. five Common cards, three Uncommon cards, a reverse holographic card of any rarity, and sometimes a Rare card. Starting with the Scarlet and Violet series however, each pack will contain one holographic card, as well as two reverse holographic cards. Unlike the basic Common and Uncommon, Rare collectables are divided into many different sub-groups, comprising Holo Rare, Reverse Holo, Half Art/Half Body, Full Art/Full Body, Secret Rare, Ultra Rare, Rainbow Rare, Promo, and card mechanics including EX/GX, V/VSTAR/VMAX, and Tag Team. Rarities can be also account for old card collectibles such as "1st-edition Base Set" and "First Generation Sets", and such collectibles are some of the rarest and most expensive Pokémon cards with some valuing at thousands and millions of dollars.
