As the title says I think I found a glitch where you can shoot up to 2 balls (sometimes 3). So far I can only do this glitch in multiplayer split screen. Don't know if this works on xbox live because I have yet to find a match so I can try it. Heres what you do: before you launch the ball, tilt the table excessively until you see a random score pop out of nowhere. Once you see the score pop up. You can now launch 2 balls into the game! You can do this everytime since multiplayer split screen has unlimited balls
