This is difficult to do in a straight-forward way. The best method is to start a game in France (or the earliest location if I'm remembering that incorrectly) with several cards (4 is a good number), make sure you have enough coins to activate auto-daub on all the cards together, and do not daub any tiles. Let the powerup bar fill naturally over time, and as you start coming up on the end of the game (when the remaining bingos are in the 15-20 range), activate your powerup - it doesn't matter what it is. As soon as the bar has finished emptying, activate the auto-daub for all your cards, and this will immediately fill your bar up again since you have let so many numbers go by without daubbing them.
