You can let the audiences roll the coin on the screen. When you perform your magic, you simply press somewhere on the screen and a hole will come out. This hole can be the same as the scene of performance, and it seems that there is really a hole on the phone. If we roll the coin, it will really fall from the phone.
Coins from different countries or regions are also supported, including Canada, China, Hong Kong, India, Japan, South Korea, New Zealand, Russia, Singapore, Taiwan, England, as well as America.
