"Spooky" Halloween Games

You could play "Hide the Pumpkin" and you get a mini pumpkin and hide it in one of the rooms. One of the rooms has a person dressed up in a scary mask hiding and one room has the pumpkin. Each person has to try to get the pumpkin before the scary person by checking each room. You have to hide the pumpkin a little also so each person has to go all the way into each room. If they go into the room with the scary mask person when they get close to the hiding place the person jumps out. It is soo funny the kids will scream and have a good time. They have to know the person in the scary mask though. The winner is the person who found the pumpkin in the least amount of time. Make sure you have two prizes just in case of a tie.

My mom did this for a party when I was a kid.

She got a large bag of pasta and over cooked it (I mean really over cooked, you want it mushy.) Then dyed it with green food coloring and mixed in little toys. If we wanted a favor from the part we had to dig our hands in to get it. Gross and fun. But don't put kazoos in it, they won't work afterward.

The biggest hit at that party though was the "haunted tunnel". Mom got 2 large cardboard wardrobe boxes and taped them together to make a long tunnel. She used a pencil to punch a bunch of holes in the cardboard (near the middle of the tunnel)that she stuck twinkling christmas lights through. She stapled some damp sponges to the floor of the tunnel at one end and had several lengths of black thread hanging from the celing to feel like cob webs. Both ends of the tunnel were covered in black fabric that was cut into strips. This was how the kids got into our living room for the party and once the games were over we pretty much spent the rest of the day going through it again. Loads of fun.

Edit:
I almost forgot about the bug juice. Equal parts punch and lemon-lime soda with a hanfull of rasins thrown in. bubbles will collect on the rasins making them float to the top then the bubbles pop and the "bugs" fall back to the bottom. Very fun

There's always the icky guessing game. Drape a box with black fabric and put a series of different things in the box -- peeled grapes in a bowl, wet spaghetti, jello. Have them guess what they are touching without seeing it. Alternatively, you can blindfold one kid at a time and have the others watch as the guesser makes icky faces.

A bowl of dry-ice punch (gingerale, pineapple sherbert, and a large chunk of dry ice) will give off smoke and be very spooky. Just don't touch the dry ice with your hands.
