Sevens, also known as Parliament or Fan Tan, is a free card game available on Android developed by CloverQ. The game is easy to learn and play, with a scoring system that adds longevity to the gameplay. The objective of the game is to get rid of all your cards before your opponents do.

The game starts with the player who has the seven of diamonds, and the game proceeds clockwise from there. Players must lay down cards that match the suit or rank of the card previously played. If a player cannot play a card, they must pass their turn. The game ends when a player runs out of cards, and the remaining players receive penalty points based on the cards remaining in their hands. The player with the fewest penalty points at the end of the game wins.

With a clean and simple interface, Sevens provides an enjoyable experience for players of all ages. The AI opponents are challenging enough to keep the game interesting, but not so difficult as to make it frustrating. Overall, Sevens is a great option for those looking for a quick and fun card game on their Android device.
