How to play:

1. Take out the plastic Stackball frame and place it on a flat surface.

2. Place a handful of balls in the frame (about 10-12 balls).

3. Move the frame around rapidly on the flat surface until the balls settle into place. Remove any balls that are not touching the surface.

4. It should look something like this.

5. Take turns stacking balls on each other, as you build up the stack.

6. Continue stacking...

7. Continue stacking... No skipping turns!

8. The winner is the last person to place a ball on the stack without knocking any other balls down.

Alternate version: Play in small teams of 2-3 people and set a timer for 2-3 mins. The team that finishes with the most balls on their stack wins (note: rebuilds are allowed in the team versions if you knock down the stack).
