Game Center

Game Center is the smartphone equivalent of classic sites like Minigames and Newgrounds.

In Game Center you can find an enormous number of games, all of them perfectly playable from the app interface. They're all are organized by genre and each has its own entry with a short description and a selection of similar games.

To open any of them just tap the image and then the Play icon.

The sole defect in Game Center is that it's sacrificed a bit in the way of performance in favor of quantity, meaning it's quite possible you'll hit frequent slowdowns that end up dampening the final experience in the game.
