Materials: hiding places 

Number of players: Unlimited (the more the better)

Object: To have everyone find the person hiding and join them. To be the first person to find the person hiding 

Play: One person is selected to hide. The other players count very loudly, to a set number. (20-50 works well.) When the group finishes counting, they yell "Ready or not, here we come!" 
Players scatter and try to find the person hiding. When the person is found, the people who found him, hides with him. This is when the name "sardines" makes sense. The players try to cram into the hiding place like sardines in a can. 
The game is over when everyone is hiding with the first person.
The person who found the hider first become the new hider.

Note: A country farm works really well. Large homes with lots of rooms also work well. It is really fun to play at night.
