To do this glitch, you need to play the Playboy table, this saves the options so that you have 10 balls. Once you've played it and the game saved, pick any table other than Playboy or Strikes 'N Spares. On the table menu select options and turn autosave off and then on. This will then load the save data, which includes the 10 balls option from Playboy. When you play the table, you get 10 balls instead of 3 or 5, but the ball indicator stops displaying what ball you have after ball 5.
