This is a simple Concentration style game. I created it as a tool to learn Swift. It's a fun distraction game when waiting in long lines. 1. Pick an Emoji Theme. 2. Tap on two cards to revile the emoji on the underside of card. If cards match you get 1 point. If cards don't match and you've seen the second card before so you know it's not a match you lose 1 point, you also can lose 2 points. You can't touch more than two cards at a time. You have to wait for animations to complete before touching new card. The app now uses Leaderboard High Score - With Penalties
