Reaching a sequence of around nine is a strong result; most people land somewhere between six and ten. Past that it gets hard fast, because you are holding more steps than short-term memory comfortably keeps. Use chunking and rhythm to stretch a little further.

Any tips for going further?

Group the tiles into small chunks, give the pattern a rhythm, and try to picture the path rather than memorising each tile cold. Staying relaxed helps more than straining, which tends to scatter your focus.

Is this the same as the Simon game?

It is closely related. Simon adds colours and tones and a particular four-button layout, while this is a clean grid focused purely on the growing sequence. If you like one, try the other.

Are my best scores saved?

Sequence Memory Test

Tiles light up in a pattern; watch, then repeat it back. Each round adds one more step, so the sequence keeps growing until you slip. This free sequence memory test shows how long a chain you can hold in short-term memory. Many people reach a sequence of eight or nine before it breaks. Runs in your browser, no sign-up.

How to use it

1
Watch the pattern

The tiles flash in order. Round one is a single tile; each round adds one to the end.
2
Repeat it

Click the tiles back in the same order. Get it right and the next round adds a step.
3
Reach your limit

One wrong tile ends the run. Your level is the longest sequence you repeated correctly.

When it comes in handy
