This is an easy kids party game that will fit in with any “spy” or “detective” party theme. You’ll need the clothing accessories explained below and a stopwatch or other clock for keeping time.
Have a second room, or anywhere the rest of the kids can’t see what’s happening, and make a good selection of clothing ‘accessories’. You need at least twice as many items as you have children. Things like ties, hats, jewelry, socks, shoes, whatever. You need more than one thing in each category, i.e. 6 ties, 4 necklaces, etc. Have the whole group go in and everyone put on one or more articles from the assortment. Make sure the number of items left over is enough for ½ the kids in the group.
Have them then go play another game, have a snack, anything that uses up 15 minutes or so of them all wearing their borrowed attire. Then it’s time to play this fun game.
Gather them all back together, and have them draw numbers out of a hat. Make teams out of the evens and the odds, and separate them to different sides of the room. Starting with the odds, send that group out of the room to swap their borrowed accessories among themselves. In other words, Susie takes John’s borrowed hat, John puts on Sam’s borrowed tie, etc., until everyone has changed their item.
Now send the team back to the other room to line up in front of the evens. The evens have to figure out what everyone’s wearing that’s different from what they started with. When one “odd” is figured out, have them step out of the line, until they’ve all been figured out. Time how long it takes.
Now it’s the ‘evens’ turn and it has to be harder because the ‘odds’ now know how the game is played. The evens need to switch their borrowed accessories for something new from the pile, preferable of the same type – meaning change a hat for a different hat, a necklace for a bracelet or different necklace. Once done, repeat the guessing process, time them and declare the winning team.
I’d suggest that this game should be for kids age 9 and up, but if anyone uses it with younger kids and it works, let me know and I’ll change the age range.
