A big majority of games in the App Store are casual games. Of these, physics puzzle games are among the most successful games in the App Store. They deliver pick-up-and-play gameplay that is both addictive and suitable for all ages. Although these games do not actually teach physics, outside of basic projectile motion, angles and structure stability, they do carry a more realistic element than other games. Physics puzzle games have a considerable population in the App Store because the gameplay requires quick touch control, multitouch, and even tilting making it well suited for the iPhone, iPod Touch, and iPad.
Best Physics Games in the App Store: CUT THE ROPE
Cut the Rope is a cute puzzle physics game which for the most part requires you to utilize centripetal force and tension (in simplistic scenarios, of course) in order to bring the candy to that little critter inside the box. The gameplay is unique as it stays away from traditional projectile or building blocks gameplay often used in most physics puzzle games. Chillingo, the developer, has stated that Cut the Rope is the fastest selling iOS game to date. Cut the Rope is truly a must-have for puzzle gamers, as it is unique, innovative, and just plain fun to look at. Expect it to be somewhere at the top of the charts for a long time.

Best Physics Games in the App Store: ANGRY BIRDS
Angry Birds puts you in control of a slingshot with your ammunition being a diverse set of angry birds. Your objective is to attack those pesky piglets who stole the birds’ eggs by smashing through their structures. Although the gameplay isn’t unique, let alone the physics element, the overall execution, from the characters and storyline all the way to the cute graphics and insane number of levels, easily trumps its predecessors. Angry Birds is one of the most addicting and popular puzzle games ever in the App Store. Definitely a must-have for any iDevice owner especially one who enjoys a touch of action added in a physics puzzle game.

Best Physics Games in the App Store: STAIR DISMOUNT
Stair Dismount is one of those “injury” games, which are quite unique in the App Store, wherein you are tasked to achieve the highest score possible based on how much damage you are able to inflict on your character. Don’t worry; your character is simply a rag doll or a crash-test dummy. The gameplay of Stair Dismount is to find the exact location where to push your character and the amount of force you need to generate maximum damage as your character falls down a set of stairs or from a high structure. Your character follows rag doll physics, and you have to perfectly utilize this in order to inflict the most damage. Most of the gameplay obviously is simple trial and error as rag doll physics offers almost limitless possibilities. The best part is really watching your rag doll bump, twist, and somersault, and hearing those bone-crunching sounds.
