Challenges are themed sets of activities in SuperBetter. They're what you play.
Each Challenge includes an epic win (a goal), daily quests to help you achieve the epic win, and bad guys to battle that get in the way of your progress. When playing a challenge you will also activate power-ups and check in with an ally each day.
A Hero account has a library of over 40 Challenges with themes related to mental health, life skills, and emotional, physical, social & mental resilience. There is no set length for Solo Challenges. Most can be completed in 2-4 weeks or less.
A Host account includes over 90 Challenges that can be hosted for squads. Squad Challenges always have 5-days of activities. Some topics that need more than a week are broken down into a series of weekly epic wins to fit the 5-day format. Hosts can also design their own Challenges.
