Kolam Kambi (South Indian Line-Drawing Puzzle)

Mark out an evenly spaced grid of dots on the ground using chalk or a trickle of rice flour.

Try to draw a single continuous looping line that winds around and encloses every dot on the grid.

The line must never lift off the surface, cross itself, or touch any dot directly.

Plan your path in advance since a wrong turn partway through can trap you with no way to finish the pattern.

For a group challenge, players can race to complete their own dot grid first or take turns extending one shared pattern.

A successfully completed loop that encloses every single dot without gaps wins that round.
