Toggle is a game in which you tap, swipe, and pinch your way through colorful rectangles, circles, and other shapes.
The game starts out easy to pick up, but as you progress, the challenge increases. Each level has a specific theme, and the difficulty increases as well. The harder the level is, the more you will earn as you progress.
If you ever get stuck, you can always reach the end by pressing the "home" button at the top of the screen. It will then take you back to the beginning of the level, and you can start again from there.
You will earn stars as you progress, and each star is worth a certain number of points. The higher the star, the higher the reward you get.
