Leaderboards

Local leaderboards allow you to input your name when getting a highscore.  Once you've pinched or pressed the text input area, please look around for the virtual keyboard (it may spawn behind you).   Great for when you're playing with family or friends in your own home!  You can clear these leaderboards by going to game Settings > Saved Games and selecting Clear Leaderboard Score

Global leaderboards require you to be signed into a Game Center account.  Your score will be shared with other players from all over the world!  These scores clear each week.
