Games for Adults
The person with the 'Killer' chit is the killer while the rest of the players mill around the yard or room. The killer chooses his victim and slowly makes his way towards him or her. Then, very quietly he whispers 'You are Dead' in the victim's ear. The victim shrieks and feigns death. Lights are then turned on and the players try to name the killer.
If any of the players guesses and gets the wrong killer, he dies immediately. The lights go off again and the game continues. Every time there is a murder, the players have a chance to guess the killer. A correct guess results in the death of the killer and the game ends.
Ask a neutral judge to rate the performance of each team. Make provisions for scary background music or special effects, if possible.
Games for Kids
Wrap the Mummy
Divide the kids into pairs and supply them with a roll of one toilet paper per team. One kid acts as a mummy while the other wraps the toilet paper around the mummy. The team which finishes the toilet paper first and succeeds in completely wrapping the mummy, wins the candy prize.
It's So Gross
Take random food items and turn them into gross mass. For instance, mash the bananas and peel the grapes so that they become slimy. Take some cold ketchup out of the refrigerator and put it in an opaque plastic bag. Soak a few sticks of pretzels and mushrooms. Put each of these food items in a separate self locking plastic bags.
Ask the kids to stand in a circle and pass the bags around. The kids stick their hands inside the bags and try to identify the food item. The kid who guesses right wins the prize!
