How to make a Halloween mystery box

Making a Halloween mystery box is really quick and easy. Start with a fairly large cardboard box that still has all its flaps, and close it shut.

Then draw a large circle in the middle of the box, cut it out and fasten the flaps back in place with some sticky tape.

Next, take an old white sheet and cut it roughly to size so that there’s enough to cover the box plus a bit extra.

Place it on top of the box and cut a slit in the sheet over where the hole in the box is. This is where you’ll put your hand in. Then draw two eyes and a mouth on with a marker pen to make it look like a ghost.

Time to play!

Once you’ve made your DIY mystery box and you’ve got a large selection of tricks and treats, it’s time to start the game!

Take the box out of sight while you put a trick or treat inside, and then replace it on the table. Do the same for each player and watch them squirm as they try to guess what’s inside the box!



Make sure you’ve got a mixture of tricks and treats to put in the box and have some extra prizes on hand for people who correctly guess what’s in the box.


Stock up on plenty of Halloween sweets and chocolates like these, and any leftovers can be given to trick or treaters or used to fill party bags.
