Prince of Persia Classic iOS Hidden achievement

I have gotten 17 of the 18 game center achievements in Prince of Persia Classic HD on my iPad. The last achievement is hidden, and I have searched the Internet on how to unlock it, to no avail. Does someone know how to unlock this last achievement?


Solution 1:

The pc version of the game has 20 achievements and one of them requires resetting the game and make in record time. Try this.
