Kendama

Hold the kendama by its handle, letting the ball hang down on its string.

Swing the ball upward and try to catch it in one of the three cups on the handle.

Once comfortable catching in the cups, try landing the ball's hole onto the spike at the top of the handle.

Progress to combination tricks that chain multiple catches together without dropping the ball.

For group play, take turns attempting the same trick and see who lands it in the fewest tries.
