Reach the open spot in the circle before your opponent.
Four or more people sit, stand, or kneel in a circle facing in. One person goes around the circle touching each person on the head as they pass and saying "Witch". The person on the outside continues around the circle tapping and saying "Witch" until he/she decides he/she's ready. He/she then taps someone on the head and says "Ghost" and proceeds to run around the circle. The "Ghost" must run around the circle in the opposite direction. Both are racing for the open spot in the circle. The loser gets to be the caller for the next round. Variations on this game are many including hopping or skipping, or perhaps in piggy-back.
