"Random Number 99" is an app that randomly generates numbers up to 99.
The numbers are displayed in a large font size, so many people can see them at the same time.
An operation is easy. A start and a stop only tap the window.
You can use easily by the bingo game, a small-scale lottery, party, etc.
Probably, a lottery while you sound favorite BGM which you save at iPad will be pleasant.
If iPad is connected to a projector or a loud speaker, force will increase further.
