How far can people get?

Reaching a sequence in the high teens is a strong run, and most people break somewhere between rounds eight and fifteen. Using the tone as well as the colour helps, because two cues are easier to recall than one.

Can I turn the sound off?

Yes. There is a mute control, and the game still works on colour alone. Browsers also keep audio silent until you interact with the page, so the first tap is what switches the sound on.

What is the trick to remembering?

Hum or sub-vocalise the tones, and give the sequence a rhythm so it plays back like a little tune. Chunking the pattern into groups of three or four also makes a long sequence far easier to hold.

Are my best scores saved?

Your best result for each game is kept in your browser so you have something to beat next time. It lives only on this device, so clearing your browser data or switching to another device starts you fresh. Nothing is tied to an account because there is no account.

Does anything I do here get sent to a server?

No. Every game runs locally in your browser. Your scores and any text you type stay on your own device, nothing is uploaded, and nothing is logged or stored by us. Once the page has loaded it keeps working even if you go offline.
