Watch. Remember. Repeat.
Simon Says is a free online memory game: four pads play a growing sequence of lights and tones, and you repeat it back — one wrong pad ends the run, every round adds one more step until you can't.

The sequence grows by one step every round, and the playback gap shrinks from ~450ms to ~220ms as rounds climb. Best streak lives on this device only. Tones are synthesized live with the Web Audio API — no audio files.
