Simon Says

How to play

Watch the color sequence flash, then repeat it back in the same order by clicking the four colored buttons. Each round you clear adds one more step to the sequence, so the game gets progressively harder to memorize. A single wrong click ends the run at your current level.

Frequently asked questions

Is my best level saved?

Yes — your highest level reached is saved locally in your browser, so it persists between visits on the same device.

What's a good level to reach?

Most people start losing track somewhere around level 8-12, since that's roughly the limit of short-term sequence memory without a memorization trick like chunking the pattern into smaller groups.

Does it work on phones?

Yes — tap the colored buttons the same way you'd click them with a mouse.
