Ruckus

From BoardGameGeek:

Ruckus is a fast-paced, real-time card game of collection and cunning. All players act simultaneously, forming families of matching cards, stealing opponents' sets, drawing from the central pile, or completing their own collections without waiting for turns. Timing and observation are key, as players must manage their hand while reacting to others' moves. Rounds end when a player empties their hand and shouts “Ruckus!” Points are scored for cards in completed families, with penalties for leftover cards. The game continues across multiple rounds until a player reaches the target score, and the winner is the one with the highest total. Quick thinking, strategic steals, and real-time chaos make every round lively and unpredictable. -description from the publisher
