About this game

Simon is the iconic 1978 electronic memory game where each round adds one new color-and-tone to a sequence you must repeat. It trains both auditory and visual sequential memory.

Tones are generated live with the Web Audio API: G4 (green), E4 (red), C4 (yellow), G3 (blue). Use Q / W / A / S keys for keyboard play.
