Bin Bin Ttak Ttak

Players stand in a loose circle facing a designated leader in the center.

The leader calls out a number while pointing at the group, and players must quickly form clusters of exactly that many people.

Anyone left without a group when the count is checked is eliminated or takes on a small forfeit.

The remaining players reset into a loose circle, and the leader calls a new number for the next round.

Play continues with shrinking numbers until only a small group of fast movers remains.
