Candy Crush Saga manages to be one of the most compelling, entertaining, and socially-engaging match 3 games currently on the App Store with deep Facebook integration and an addictive reward scheme.
The concept of Candy Crush Saga is very basic. Match three similar pieces of candy to advance to the next level. Each level has a certain number of candy matches needed, with bonuses, combos, and high-score opportunities, all integrated with Facebook for friendly competition. The game is free to play, but there are a number of upgrades, including lives that allow you to keep playing if you lose on any given level (which can happen frequently when you reach higher levels) or charms that slow down gameplay or swap out different colored pieces of candy. The game is reminiscent of Candy Land or the old Christmas specials of the 60s and 70s, complete with pastel colors and cutesy winter monsters.
If you enjoy match 3 games, Facebook games, or strong themes with compelling gameplay, Candy Crush Saga should be on your iPhone or iPad. You don't need to spend a dime to enjoy the rich gameplay experience here, and even if you do, the rewards are often exciting. It's not the most original game on the App Store, but it is very polished and enjoyable.
