This app is a simple pool table simulator. It does not have an AI to play against you, but you can play the game against your friend, or practice by yourself. The rules of the game are not imposed on you and you can play by whatever rules you choose. You can strike any ball you want, or pick up any ball and carry it to a different spot on the table, carry it off the table, or carry it back to the table. Click on the question mark icon to see a help page that describes how to control the app.
