Sequence Memory Test

How to play the sequence memory test

1. Tap Start. A 3×3 grid of nine sleepy tile faces appears, and the label above it says Watch closely! Taps are ignored while the sequence plays.
2. Level 1 wakes up a single tile: it lights up and opens its eyes. When the label switches to Your turn!, tap that tile.
3. Every new level replays the whole sequence so far, then adds one new tile at the end. Each tile glows for 0.5 seconds with a 0.25-second gap before the next, and the same tile can light up more than once.
4. Tap the entire sequence back in order. Each correct tap makes the tile flash with a happy face, and a progress meter shows how far through the sequence you are. Clear the level and you’ll see Nice! with the next level number.
5. One wrong tap ends the run. You’ll see Oops!, and the tile you should have pressed glows, so you can see exactly where it slipped. Your score is the number of levels you completed, shown as “Level 7”, for example.

Sequence Memory has one mode, Test mode, with fixed difficulty, so every run counts toward your records.

If the flashes feel too quick, turn on Large text & slower pace in Settings. Tiles then glow for 0.65 seconds with 0.3-second gaps.

What it measures

This is a visuospatial short-term memory task. You hold a list of positions, in order, for a few seconds and play it back. Think of it as your memory span for where and when, rather than for words or digits.

Memory researchers use a close relative called the Corsi block-tapping test: an examiner taps a row of blocks and you copy the order. In that version each trial is a brand-new sequence, and adults typically manage about 5 to 7 blocks (Kessels et al., 2000; see the 2021 methodology review).

Our game follows the Human Benchmark “Sequence” format instead, where the sequence is cumulative. The old part replays every round, so you get free rehearsal and only need to add one new tile. That is why scores here run well above Corsi spans. The two numbers can’t be compared directly.

Some honest limits:

• Practice raises your score on this game. A large 2016 review (Simons and colleagues) found that trained tasks improve reliably, while evidence for transfer to other tasks or everyday life is thin. A new personal record means you got better at Sequence Memory. That’s a fine goal for a daily rep, and we don’t claim more.
• Scores move from day to day. Sleep, noise, a notification or one slippery tap can cost you a few levels.
• It is not a medical or IQ test. It doesn’t diagnose anything.

Sequence memory test averages

The reference point comes from Human Benchmark’s Sequence Memory test, which uses the same cumulative format: its public figures put the median at level 9. After each run, Brainsquat’s result screen shows a rough band based on that reference, such as “Top 20–30% of players,” never an exact percentile, and names the source.

What your level means for you:

Read the reference with three caveats. Human Benchmark players choose to take the test, mostly on desktop with a mouse, and their ages aren’t recorded. That’s why the band is coarse on purpose.

Timing matters less here than in a reaction test. Phone browsers add roughly 58–70 ms of touch delay (Pronk et al., 2020), but your taps aren’t timed, so that delay doesn’t cost you levels. What phones do add is the risk of a mis-tap on a small tile.

Tips for a better, fairer score

1. Draw the shape, not the dots. Connect the positions into a line or a letter: an L, a zigzag, a triangle. A shape is easier to hold than a list of loose points.
2. Number the tiles like a phone keypad. Top-left is 1, center is 5, bottom-right is 9. Say the string silently, like “1-5-9-6”. A spoken code plus the picture gives you two copies of the same sequence.
3. Chunk in threes. Past level 6, split the sequence into groups of three and leave a tiny pause between groups as you tap. With only nine tiles, the same tile often comes up more than once, and chunks help you keep repeats straight.
4. Watch hardest for the new tile. The old part replays every round, so check it quietly and put your full attention on the last flash.
5. Tap calmly. Speed isn’t scored, and one slip ends the run. Count your first run of the day as your honest number, since later runs include warm-up.
