Angry Birds, Cut the Rope, and Fruit Ninja are provided as examples of strong apps. Angry Birds is simple, colorful, and has sold over 500 million copies at a low price point. Cut the Rope is also inexpensive, simple, and entertaining, though it has different gameplay and objectives than Angry Birds. Fruit Ninja, like the prior two, is affordable, easy to play, and visually appealing, but additionally allows for multiplayer which enhances the fun of playing with friends.
