In this podcast. David Woodbridge gives us an overview and quick demonstration of Blindfold Pong, a free audio game for iOS.
In Blindfold Pong, you hear one or two balls, and you must move the phone left and right to hit the ball with your paddle. Using head phones or ear buds, you hear the ball heading towards you, and the ball will bounce off of your paddle when it's sound is in the center of your head.
The ball gets faster each time you hit it with your paddle, and you can change the bounce angle by hitting it at the left or right side of your paddle. As you move from level to level, your paddle gets smaller and the balls get faster. You can change the ball sounds and many other settings in the game.
