🕹️ How to play

How to play the sequence memory test: Press Start and the grid lights up square by square while the frame glows blue and the bar says Watch — taps don't count yet. When the last light goes out the frame turns amber and the bar says Your turn: tap the squares back in the same order.
How levels work: Get the whole sequence right and the next level replays it from the beginning with one new step added at the end. Earlier steps never change, so each level you only need to remember one more square. Level 1 is a single step.
What happens when you miss: In Levels mode you start with 2 replays: a wrong tap spends one and replays the same sequence, and your score stays. You can also spend one on purpose if you lose track. Out of replays, the next miss ends the run. Test mode has no replays — one mistake ends it.

📖 Rules & variants

The rule in one line: watch the order the squares light up, tap them back in that order, and the sequence grows by one step every level.

Quick start: ① press Start; ② watch (blue frame, taps ignored); ③ when the frame turns amber and you see Your turn, tap the sequence back — the progress bar fills one segment per tap.

Scoring: your score is the longest sequence you reproduced in full. Miss on level 6 and your score is 5 — the level you missed doesn't count. The cap is 50 steps; clearing level 50 is a perfect clear.

The same square can appear several times, even twice in a row. Back-to-back repeats always have at least 300 ms of darkness between them and the second flash sends out a pulse ring, so two flashes never blur into one long one — tap that square twice.

Two modes: Levels starts with 2 replays, spent automatically on a miss or on purpose; clearing steps 10, 20, 30 and 40 gives one back, up to 3. Test has no replays and a fixed normal pace — one mistake and you're done, which makes it the score to compare. Each mode keeps its own best.

Three paces (Levels only): Slow lights each square for 650 ms with 350 ms gaps; Normal uses 450 ms and 250 ms; Speed-up gets faster as the sequence grows, down to 260 ms and 160 ms. Pace changes how hard it is to read, not the rules.

No input timer: take your time once it's your turn. Every tap counts and lights instantly, fast taps are never dropped, and an extra tap is judged like any other. On a keyboard use keys 1–9 in reading order (7/8/9 is the bottom row) or Tab and Enter.

Tips: don't memorise isolated squares — trace the lights as a route (top left → center → bottom right is a diagonal); chunk it into groups of three or four and say them in your head; when one square repeats, count the pulse rings. If long sequences feel slow, switch to Speed-up.

Example: the sequence top left → center → top left → bottom right. Level 1 shows top left; level 2 adds center; level 3 adds top left again; level 4 replays all three and adds bottom right.

Playing with friends: pass one phone around, one run each, highest step count wins and equal scores tie. For a fair contest agree to one Test-mode run each. With kids, turn the sound on — the nine squares play a pentatonic scale, so any order sounds pleasant to hum along.

❓ FAQ

How does the sequence memory test work?

Squares on a 3×3 grid light up in order; when the frame turns amber you tap them back in the same order. Each level replays the whole sequence and adds one step, and your score is the longest sequence you reproduced. Taps while the lights are playing are ignored, so an early tap never costs you.

What is a good score on a sequence memory test?

We don't show population averages — only your own scores and your last 10 runs. Our just-for-fun ranks call 4–6 steps Steady, 7–9 Sharp, 10–12 Expert, and anything from 13 up increasingly rare. Scores swing by two or three steps with focus and fatigue, so the trend matters more than a single run.

How can I remember longer sequences?

Turn the lights into a route and chunk it. Picturing a finger tracing a path across the grid is far easier than holding nine separate positions; then group the path into threes or fours and repeat them silently. Since each level only adds one step, use the replay to confirm the route is unchanged and save your attention for the new last square.

What's the difference between Levels mode and Test mode?

Levels mode forgives mistakes: you get 2 replays, earn more at steps 10–40, and can pick Slow, Normal or Speed-up. Test mode has no replays and a fixed pace — one mistake ends the run — so its score is the one to compare with friends or your past self. The two modes keep separate bests.

How do I tell when the same square lights up twice in a row?

Watch for the dark gap and the pulse ring: a repeated square goes dark for at least 300 ms, and the second flash sends a ring outward (a static outline if you use reduced motion). A ring means tap that square twice. With sound on you'll also hear the same note twice.

Is this the same as the Simon memory game?

It's the same family of game: watch a sequence of lights, repeat it, and one step is added each round. This version uses a single-colour 3×3 grid where position is all that matters, so it works for colour-blind players, and it adds replays, three paces, a strict Test mode and unmistakable watch / your-turn signals.
