Pokémon offers an online version of the trading card game on its official website. The free download comes with four free online theme decks and offers single player and multi-player options.
Players start with four decks and are able to battle both real people and computer-controlled opponents. The Trainer Challenge allows players to brush up on their skills while Versus Mode and Tournament Mode bring real players from around the world into the game.
Players can collect booster packs and improve their decks just as they would when playing the game offline. Pokémon TCG Online also has an in-game trading feature that allows players to swap cards.
