Looking at it you'd think you need to open the game 5,000 times, and you don't, its only 50, but after you unlock it, its 500. Very odd and like another player said, you can just used the "Reset Game' feature in settings. So dont get thrown off by this 'daunting' task, its only 50 resets. You should be able to do it in about 2 minutes (AT MOST).
