Uppu Kappurambu (Salt and Camphor)

All players sit in a circle while one player, chosen to start, walks around the outside holding nothing visible.

The walking player secretly drops a small marker or handkerchief behind one seated player without being noticed.

That seated player must feel or notice the marker and quickly stand up to chase the walker around the circle.

If the walker makes it back to the empty spot before being tagged, the chaser becomes the next one to walk around and drop the marker.

If the chaser tags the walker first, the walker must sit in the middle or take a forfeit, and a new walker is chosen.
