- Take a route map (difficulty level 1 to 10) and look at the sequence of holds. The routes always follow a deliberate line.
- Apply magnesium to your fingers for a better grip.
- Use both hands when climbing. However, only 3 fingers may touch the ball at the same time. It doesn't matter which fingers you use, they can always be different ones.
- The Boulderball is always held freely in the air when climbing. You are not allowed to put it down or support it.
- Make sure you have a non-sensitive surface, as the Boulderball can "crash".
- Hold the Boulderball up on the first two holds indicated on the route. Hold hold 3 of the route with a third finger. Now release hold 1 and move on to hold 4 (does not have to be with the finger of the first hold). Follow the route in this way.
- Once a finger is positioned on a grip, it may not be replaced by another. However, the finger may change position on the hold, i.e. slip.
- If you have managed the ascent and descent without "falling", you have reached the goal.
- You can also climb freely or come up with your own routes.
