Card-e Cards is 9-Volt's multiplayer mode in WarioWare, Inc.: Mega Party Game$!. It involves each player taking turns to pick cards to put into the deck. When a player picks up an e-card, all the cards in the deck are put into the e-Reader and that player has to complete all the microgames in order to put them into its own pile. Should the player fail a microgame at anytime, the session ends and all cards in the deck, and the player's own cards, are sent to the Pile. Any player who beats all the microgames picked will not only receive the cards in the deck, but also the cards lost in the pile. Also, while a player is playing, their opponents can go and steal other cards by walking over to that player's pile and pressing when the bar next to it is full. If there are no cards left to pick but there are cards still in the deck and/or pile, players battle for the remaining cards by playing a multiplayer microgame. The winner is the one who has the most cards at the end.
