Steal

Stealing is a gameplay mechanic where the player matches two or more of a kind, based on the icon in the top left corner, and uses the cards to steal a card from an opponent.

Two of a kind - blind steal
To steal a card, play any two of a kind into the discard pile. For example, if you had two Tacocats, you could play them as actions and then choose a player. That player would hold up their cards and you'd take a card at random.

Three of a kind - "Go fish"
Playing three of a kind lets you NAME the card you want, and the player of your choice has to give it to you. If they don't have the card you want, you're out of luck, so be sure to keep an eye on who still has Defuse cards.

Card icons
You can play any card as two or three of a kind, as long as the icons in the upper left match. For example, on each Shuffle card the artwork on the face of the card varies, but the icon is always the same. So, instead of playing the Shuffle cards as actions to shuffle the deck, you could play them as a pair and use them to steal from another player.

Five different icons - Steal from the Discard pile
If you play any 5 cards that have different icons in the corners, go through the Discard Pile to take any single card you'd like.
