The upper part is a cylinder, and the lower part is a non-stop rotating disk with holes. When you tap the screen, a small ball will fall from the cylinder and roll into the hole.

When the ball falls into the center of the big hole, the big screen will start to roll, and a random lottery draw.

When the progress bar at the bottom of the screen reaches its apex, as long as you tap the screen, you will drop the ball indefinitely. Although there is a time limit, it is also a time to test your hand speed.

What's more interesting is that there are different little monsters waiting for you to collect. Come and try, unlock more ways to play together and win more rewards.
