With a free Player account, you can play Squad Challenges hosted by others.
If you don't have a Host to invite you to play, or if your Host doesn't host Challenges every week, here are some options.
Most weeks, SuperBetter will host a Squad Challenge that is available to everyone with a SuperBetter Player or Hero account to join. We do this so those with a free Player account will always have a Challenge to play. And, it's a fun way to bring our whole community together.
You might also consider subscribing to a Host Account for yourself and hosting your own Challenges for a group of friends, or for a club that you belong.
