The application is a rhythm-based game based on the Pokémon Trading Card Game. The goal is to tap Pokémon in rhythm to the music and sounds going on in the game.

Gameplay
The game's basic gameplay is to tap on the screen in rhythm with the song's lyrics. One Pokémon card is on the screen at a time, corresponding to the respective Pokémon of the song. As the time to tap the card approaches, the respective energy symbols of the card approach a circle; the more centered the symbol is on the circle, the more accurate the player is.

The game features two gameplay modes. One on which the cards and symbols appear, and one that the player taps based on just the sound. The player's accuracy is measured in points, and there is an online leaderboard for the smartphone versions.
