Sequence Memory
The 3×3 grid lights up in a random order — watch, then tap the cells back in the same sequence. Every level adds one step and plays a bit faster. A single wrong tap ends the run; your score is the longest sequence you completed.
HOW TO PLAY
- 1Watch the order the cells light up in
- 2Tap the cells back in the same order when it's your turn
- 3Each level adds a step — one wrong tap ends it

About this game
Sequence Memory is a classic working-memory drill: you hold both the positions and the order of the flashes at once. Level one is a single cell, and every level appends one random step — there's no pattern to memorize, only attention.
Cells are locked during playback so you can't jump ahead, and rapid-fire tapping can't corrupt the input order. An optional sound toggle gives each cell its own pitch. Leaving the tab auto-pauses and replays the current sequence on return.
How scoring works
- Score = the longest sequence you reproduced correctly, i.e. levels cleared — higher is better.
- Playback speeds up as you climb: about 0.6s per cell early, down toward 0.3s later.
- One wrong cell ends the run; your best level is stored on this device.
- Most people hold 7–9 steps; past 12 is genuinely strong working memory.
Frequently asked questions
How does it work?
A 3×3 grid flashes cells in a random order; after playback you tap them back in the same order. Level one is a single cell and each level appends one step. A wrong tap ends the run — your score is the longest sequence you completed.
Can I tap during playback?
No. Cells are locked while the sequence plays — input only counts in your turn. That keeps runs honest and stops fast tapping from scrambling the order.
Does playback speed up?
Yes. It starts near 0.6s per cell and tightens toward 0.3s at higher levels. You can enable sound in the HUD — each cell gets its own pitch, which makes the order easier to encode.
Does switching tabs change my sequence?
The game auto-pauses and covers the board. Resuming replays the same sequence from the top — progress is kept, but pausing can't be used to peek.
Where is my best level stored?
Only in this device's browser localStorage — nothing is uploaded, no account, no global ranking. The result screen can clear it in one tap.
How many steps is a good score?
Most people hold 7–9 steps reliably; past 12 is genuinely strong working memory. Chunking the sequence into groups or a little story beats raw memorization.
