Simply tap the question mark or shake and view the result. Tap the coin or shake to flip again.
Spinning coin animation, sound, text, vibration, shake-to-flip and coin type are all configurable via the Settings menu. Verify the flip algorithm is truly random by running the built-in Self Test and flipping the coin 100,000 times while watching the results in real-time. (Sorry, no cheating!) Add new coins from the Android Market by clicking Settings -> Get More Coins.
