Sardines

This is also known as "Reverse Hide and Seek." It's an ideal game for a big group, more so than traditional Hide and Seek (in which everyone is hiding at the same time and know where their friends are, making it really lame when they all find each other once they're found).

To play Sardines, everyone starts in one room or location. One person is selected to go and hide, while everyone else stays and counts to 100 (or whatever number they agree to with the "hider"). When they reach 100, everyone splits up to search for the person who is hidden. If anyone finds him/her, they hide with him/her. This continues until everyone is hidden except for one person who is still looking for the original hider (and everyone else who has joined him/her). The game can get pretty silly if 6 people are trying to fit under the same table or in the same closet.

This game also works outdoors, so long as the area is limited (such as a park or yard).

The Adverb Game

Send someone out of the room while the rest of the group chooses an adverb.

An adverb is (more or less) a word describing a way that something can be done. Examples: softly, angrily, musically, solemnly, cheerfully, flirtatiously, desperately.

The person who left the room is called back in and chooses picks a few people from the main group to act out a scene, such as “shopping for groceries,” “on a first date” or “washing the dishes.”

The actors pretend to perform the task, but do so according to the adverb the group selected. (Flirtatiously would involve a lot of giggling, winking and hair-tossing, for example. Musically might have everyone singing their conversations.)

The individual then has to guess what the adverb is. When they succeed, they pick someone else to leave the room and the game begins again.

Smurfing

To play "Smurfing," select one person to leave the group. Everyone else sits together and chooses an activity that ends in "-ing." Examples: crying, laughing, kissing, picking your nose, blowing out candles.

The person returns to the group and tries to discover what the chosen activity is, by asking one person at a time a question about their "smurfing" habits, or "smurfing" in general.

The person might ask questions like these:
"When is the last time you smurfed?"
"Do you smurf alone?"
"Does everyone smurf?"
"How often do you smurf?"
"Is smurfing embarrassing?"

They question can only be posed to one person at a time, although it may be asked more than once.

This worked really well once when my FHE group played. I picked the word; it was "dying."

"How often do you smurf?" resulted in several possible answers:

"I am constantly smurfing," or "I can only smurf once, and I haven't yet."

You might want to set limits on what words can be chosen to keep the game appropriate.
