Push4

Rules of the game: The player chooses the color he wants, then puts his ball into the upper hole. If there is already a ball in the seat, it will be pushed down one square. If you add a ball with 5 balls already placed vertically, the ball at the bottom will be pushed out. The ball that was pushed out can be used again. If there is no match even after placing all the balls (20 balls), it will be treated as a draw. You can use the stick to remove all the balls. If you place four or your colored balls in a row in horizontal, vertical, and diagonal directions, you win. —description from the publisher
