Two paddles face each other across a 600 by 400 court and knock a ball back and forth. You score when the ball passes the paddle on the far side, and the first player to 7 points wins. Both paddles are driven from the same keyboard, so this is a two-player game at one screen.
A point goes to a player each time the ball leaves the court behind their opponent, and the ball is then served from the centre toward whoever conceded. There are no bonus points and no clock. First to 7 takes the match. Every paddle hit multiplies the ball's horizontal speed by 1.05, up to a cap of 14 pixels per frame, so long rallies get progressively faster.
No. Both paddles are controlled by keyboard, so you need a second player sharing the keyboard with you.
Until one side reaches 7 points. There is no timer, so the length depends on how long the rallies run.
Yes — on a touch screen the game shows on-screen buttons, and games played with a mouse work by tapping.
