Rules:
1. The Offensive player’s hand must be below the waist.
2. The Victim should attempt to see the circle without looking down. In other words, by peripheral vision, the Victim realizes there is a circle-hand event occurring. The Victim has two possible methods to win the game:
a. The Victim does not look down at the signal. Instead, the Victim stares the Offensive Player in the eye and says, “I’m not going to look down.” (or words to that effect.)
b. The Victim does not look down at the signal. Instead, the Victim quickly pokes his index finger through the Offensive Player’s circle-hand display. If he can poke inside and break the circle, then that person wins, and gets to hit the Offensive player in the bicep. This action requires excellent motor skills (to poke the circle without actually looking directly at it.)
3. If the Victim looks at the circle, he loses (and is hit.)
4. If the Victim attempts to poke the circle and misses, he loses (and is hit.)
5. If the Victim attempts to poke the circle and Offensive player closes the circle, trapping the Victim’s finger, then the Victim loses (and is hit.)
It is customary to playfully “wipe off the hit” after it is delivered. (Quick open hand brush on the bicep.)
There is no limit on the type of distraction allowed by the Offensive Player to draw attention
signal. A good tactic is saying, “Hey, is this yours?” Or, “You oughta try one of these.”
There is no limit on the limit to the amount of times a day you can try this out. You’ll find some people are “easy to get” and some people have good alertness and peripheral vision, “tougher to get.”
