If you're frustrated by the lack of extra lives on lots of free games and know the pain of waiting for 20 minutes just to continue playing, try this trick before you *gasp!* PAY for extra lives. Try moving your phone's time and date settings one day into the future. Re-open the game, and it should be confused into thinking you've waited 24 hours between playing times. Play your game using the free extra lives, then switch the settings back to the correct date when you're done. Yes, it's clunky, but it's free!
