Do you remember playing a game where there were 10-20 objects on a tray, which you had 1 or 2 minutes to look at and then once they were covered up / removed, you had to remember all the objects?
Some people call this game "Kim's Game" (see below) or the "Memory Game"
I recently did a twist on the game for a baby shower - the items were placed on a tray and passed around, people had to remember as many as they could, then all the goodies went to the mum-to-be as a gift.
You can do something similar for a birthday party or team building exercise
