After a successful 24-hour online mathematical magic show in 2020, a group of maths communicators are back to do another ambitious and fun 24-hour online show, this time about maths and games. We're raising money for four charities close to our hearts, and one of these is Rheumatoid Arthritis Foundation.

Rheumatoid Arthritis Foundation, Help Fight RA is a 501(c)(3) charitable non-profit organization. Rheumatoid Arthritis Foundation is a volunteer-operated organization that provides support to patients battling Rheumatoid Arthritis. Rheumatoid Arthritis Foundation's vision is to be recognized as a foundation that enables patients directly to fight RA, to improve their health and create a world free of RA. Rheumatoid Arthritis Foundation works with leading hospitals, doctors and researchers to find more effective ways to treat RA and — ultimately — cure it.
