Front-Facing Camera required to play Drop 7 by Zynga

I love Drop 7. I have played the game off and on for years. The only reason I dont give this game a 5 star rating is due to two requirements in particular.

1. This game is incompatible with the original iPad, and
2. The game requires a front-facing camera.
----really? A camera? For what purpose?
