The Teraminx (7x7x7) is a stunning dodecahedron puzzle with 12 faces, each featuring 7 layers of colorful pieces. Invented by Andrew Cormier in 2008 and mass-produced by cube4you in 2009, it challenges solvers with 372 centers, 150 edges, and 20 corners. Its countless combinations make it a beast for dedicated cubers. Each face rotates independently, scrambling colors in a complex dance. Though not a WCA event, Matthieu Aubert’s 23:04.94-minute solve sets the unofficial record. Solve it by aligning centers, pairing edges, then finishing like a Megaminx—no edge parity needed. Brands like ShengShou ensure smooth turns. On rubikverse.com, the virtual simulator lets you tackle this giant anytime.
