Treasure Box

Treasure Box is one of those apps that, once downloaded, you'll think solely exists to test your patience.

To play, just click repetitively on the coin box that appears in the center of the screen.

The first four levels involve clicking on the box a thousand times, and the fifth level involves clicking ten thousand times. For each objective, the box will pop open and you'll receive the prize inside. A prize that, by the way, doesn't actually exist. To speed up the process, you can watch short ads to reduce the required number of clicks.

If you want to wear your hand down by tapping repeatedly on your screen in search of a reward that will never come, Treasure Box is undoubtedly an app that can fulfil this goal.
