Read full description

This ancient Egyptian spiral race game, played between roughly 3100 B.C. and 2300 B.C., involved up to six participants guiding lion- and sphere-shaped pieces across a coiled snake-shaped track. Its rules weren't fully recorded and were only recently analyzed in depth in a 2024 study, making it a fascinating untapped app concept. Prior to this app, no iPhone implementation existed.
