Treasure

Treasure is one of those apps that will seem to have the sole function of testing your patience.

To play, simply 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. The prize, 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 is undoubtedly an app can fulfil this goal.
