At least 3 people, but more people make for more fun
It’s hide-and-seek flipped on its head. With their eyes closed, seekers congregate and count to a predetermined number while one player hides.
When the group finishes counting, the hunt is on! The seekers spread out to find the hiding player; as the seekers find the player hiding, they join him in the hiding place until all the seekers have found the hiding place (packed like sardines, get it!?).
The last player to join the group becomes the next person to hide.
Find the hider before the others do, hide with him, and don’t be last!
In other variants
Play the game indoors — use the entire house for great hiding spots. You could even play a literal version and cram into the pantry with cans of REAL sardines!
