Amy and Rouge Tennis is an LCD game distributed by the McDonald's chain of fast food restaurants. They were offered as a part of Happy Meals for a limited time in 2004. This particular game was sold under another name in other regions of the world as Amy and Rouge Volleyball.
There is a directional pad which includes left and right directions and a single button. The background seems to be that of a tennis court. The object of the game is to hit a ball back at an opponent on the end of the screen using the one button. If the opponent misses the ball the score tally goes up. If you miss the ball, then the opponent's score tally will go up instead.
