Bingo Machine is a lifestyle app developed by ao-system Inc. for Android devices. It is a bingo machine simulator that randomly removes balls with numbers from 1 to 75. The app displays the history of the numbers taken out, making it easy to keep track of the game.

This app also has a card function that enables multiple people to enjoy bingo games with just this app. One person acts as a facilitator and handles the bingo lottery machine, while the other person handles the bingo cards as a participant. The app has a function to read out the balls that are taken out, making it perfect for bingo parties, events, and everyone who wants to enjoy it for free.

Bingo Machine is intended for use by multiple people at the same place, such as at a party. It is not intended for solo use. The app does not have a cooperation function between devices, so multiple people need to install the app on their devices to enjoy the game.
