The Asano family possessed a heirloom known as the Sorcerer's Trump. In the year 1984, however, it was stolen under mysterious circumstances. Seventeen years later, Sayaka, the young heiress of the Asano family, forms a group together with her friends Miki and Kyoko, and the three begin looking for the lost treasure. Heist after heist goes by unsuccessfully. Eventually, the girls organize a TV show, challenging dubious personalities to card games, hoping to find the Sorcerer's Trump in process.
Cardangels is a card game in which the player takes the roles of the three friends, playing cards against young, attractive female opponents. Four types of card games are available: poker, blackjack, speed, and babanuki (a variant of old maid). A slot machine-like introduction determines which games are played against which opponents. The player can select the amount of rounds (minimum ten) needed to win a game and advance to the next opponent. The "free play" mode allows the player to choose the type of game actively, but the amount of available opponents is lower. There is no gambling in any of the games; points are awarded for combinations in poker and blackjack. The opponents undress after losing a game; however, they retain their underwear - there is no explicit nudity in the game.
