Rock Jenga

The rules of Rock Jenga:

• You can play Rock Jenga whenever there’s lots of rocks around. Ideally, there’s a good combination of smaller and bigger rocks to play with.
• Choose a large rock to be the base
• Take it in turns to add a rock to the base or to any other rock in the structure on top of it
• You can take as much time as you want, but once you pick up a rock to use, you must use it
• If any rock from the structure falls off/hits the ground, you’re eliminated
