This is also known as hide-and-seek. As usual, an "it" is selected and while he counts out loud (ie. 1-30), eyes closed on a "home base", the rest of the players find a place to hide. Once the time is out, the "it" tries to find the other players. If one is spotted, the "it" shouts "boong ". The two ("it" and player) races to the home base to touch it (shouts: "save" upon touching home base).
The first player that loses the race, becomes the next "it". The "it" can then continue to find the others, but a new "it" is already guaranteed to replace him. The other players, if they find out, can continue to challenge "race" the "it" to the base without getting spotted or just give themselves up.
