By rolling one of the dice, a question in that category will end up on top. The participant answers that question or completes the open-ended statement. A facilitator or others in the group can ask for a longer or different response, or can add to it from their own perspective. If the discussion doesn't take off at that point, choose another participant to roll the dice or pick up another one of the twelve.
Categories range from light or low risk to medium to high risk, although the person responding can choose how deep to go.
