A monthly, story-driven puzzle subscription.
When Albert Einstein died his brain studied and dissected, and shipped all over in an attempt to better understand the source of his genius (true story). Through unique, physical puzzles we tell a fictional story of The Gray Matter Sodality (GMS), an organization seeking to reclaim and unify those brain fragments. Join GMS today!
