TAGUAN
(Hide and Seek)

2 to 20 or more players
Indoors or outdoors

One player is chosen as the it.  He remains at a base determined by all the players.  The other players then hide, and when securely hidden, they call out "It!".   The it goes to search for them.  Those who are hiding may repeat the call at their own discretion.

The game ends when all of the players are found.  The player who is first found will be the new it (the searcher) in the next round.
