Winning at least one match in a ticket-entry ensures a tradable booster pack as a reward.

After 6 April 2011, players could buy cards from the Black and White series, which have a code to be digitally represented.

It was followed by Pokémon Trading Card Game Live after TCG Online's servers were shut down in 2023.
