This is a fun and interesting casual game. In the game, you can remember the location and appearance of marine life by flipping over the marine life. If the types of marine life turned over are the same, the pairing is successful. If not, continue to turn over the next group of marine life for pairing. Players remember the appearance of marine life by flipping through the cards and pair them up two by two. If all marine life are successfully matched within the specified time, the game is won. If all marine life are not successfully matched within the specified time, the game fails!
