context_page_description: Panagiotis Verdes was born in Chiliomodi, Korinthos, a province in southern Greece, where he graduated from high school. He followed his passion for constructions and studied at the Aristotelian University of Thessaloniki from 1965 until 1970. During his career, he was primarily involved in building, road and public network constructions until his retirement in 2003.
context_section_description: Prior to Verdes's invention, the 6x6x6 cube was thought to be impossible due to geometry constraints. Verdes's invention uses a completely different mechanism than the smaller Rubik's cubes; his mechanism is based on concentric, right-angle conical surfaces whose axes of rotation coincide with the semi-axes of the cube. The patents for the cubes were awarded in 2004, and mass-production began in 2008. Verdes's mechanism allows cubes of up to size 11x11x11, as larger cubes have geometrical constraints.
