Overview

Simon: the classic memory pattern game

Simon is the electronic memory game that has tested reflexes and recall since 1978. The game plays a sequence of coloured, tone-paired flashes, and your job is to repeat it back exactly. Each round the sequence grows by one, so what starts as a single flash quickly becomes a long chain that pushes your short-term memory to its limit. Get one wrong and the game is over — your score is how far you got.

This version pairs each of the four pads with its own musical tone, just like the original, which makes the sequences easier to remember as little melodies. It runs entirely in your browser, saves your best round, and works with a tap or a click on any device.

Frequently asked questions

How does Simon help memory?
It exercises your working memory and 'chunking' — grouping items into larger units. Associating each pad with its tone turns a list of colours into a remembered melody, a classic memory technique.
What's a good Simon score?
Most people manage around 8–12 before slipping. Reaching the high teens or beyond takes real focus and a good strategy for remembering long sequences.
Why do the pads make sounds?
The tones are part of the original game and a genuine memory aid — the sequence becomes a short tune, which is easier to recall than colours alone. Your device must allow audio.
Is my best score saved?
Yes — it is stored in your browser on your device and is not sent anywhere.
