Stache is an engaging card game available on Android, inspired by classic games like Thirty-One and Knack. Players aim to form winning combinations by collecting cards of the same suit to score up to 31 points, or by gathering three cards of the same rank from different suits to achieve 30½ points. The game encourages strategic decision-making as players can swap cards, skip turns, or knock to close the round, adding layers of interaction and competition.

The gameplay features an elimination format where each player starts with three lives. Players who lose all their lives enter a "Swimming" phase, where they must avoid further losses to regain a life. The round concludes when a player achieves a "Stache" or knocks, leading to an exciting battle of wits until only one player emerges victorious. Stache offers a fun and strategic card game experience for players of all skill levels.
