When playing 4 in a line game sometimes one player and two players will block from making a line so you end up longer on the game trying to create a line and sometimes you end filling out five boxes to complete a line to win they as to be a way removing this person which is blocking someone from making a line like if not active also sometimes they will complete a random box to win a prize as well I think they must complete a line to win a prize I think you're developers could do this
