Stare at your opponent until they blink. You are trusted not to blink (honor system), and if you do, it is up to you to go to a different level to try again. In the bottom left hand corner it tells you: Difficulty; which is either 1,2,3, or 4. The time varies if you have different opponents. IT WILL BE DIFFERENT (PROBABLY) EVERY TIME. Even if you have the same opponent. Press the back button to go back to the main menu. :D enjoy!!!
Love and Favorite!!!!! Fun fact: Snakes don't actually blink...
