Squares in a 3x3 grid light up one after another. Repeat the sequence by clicking or tapping them in the same order. Every level adds one more step, so your score shows how long a sequence you can hold in working memory.

How to use the Sequence Memory Test
Press Start test. Choose speed, lives and sound first if you like.
Watch the squares light up. On level 1 only one square flashes.
Repeat the sequence by clicking or tapping the squares in the same order, or use the number pad keys.
Keep going: each level replays the whole sequence plus one new square.
See your score: the longest sequence you repeated correctly, saved to your history.
What the sequence memory test measures
This game tests visuospatial working memory: your ability to hold a series of locations in mind and recall them in order. It is closely related to the Corsi block-tapping task, a test psychologists have used since the 1970s, in which an examiner taps blocks in a sequence and the participant repeats it. Unlike the Corsi task, this version keeps the same sequence and adds one step per level, like the classic Simon toy.

Strategies that work
Chunk the sequence. Treat every 3 or 4 steps as one unit ("top row left to right, then centre").
See shapes. Paths often form letters, lines or triangles that are easier to remember than single squares.
Name the positions. Number the squares 1 to 9 like a phone keypad and remember the digits.
Use sound. Turn on Sounds: each square has its own note, so the sequence becomes a short melody.
Stay relaxed. Rushing your clicks causes most mistakes on long sequences; the input has no time limit.
Frequently asked questions
How is the score calculated?
Your score is the length of the longest sequence you repeated without a mistake. If you complete level 9 (a 9-square sequence) and then miss a square on level 10, your score is 9. In three lives mode a mistake costs a life and the same level is replayed.
What is a good score on a sequence memory test?
There is no official norm for this exact game, because results depend on speed, grid size and practice. As a rough guide, many first-time players reach somewhere around 6 to 10, which fits classic research on short-term memory span (about 7 ± 2 items). Scores in the teens usually come with practice and strategies such as chunking or tracing the path as a shape.
Does the sequence change every level?
No. As in the classic Simon-style game, the sequence keeps all previous steps and adds one new random square at the end. You only need to remember one new square each level, but you must repeat the whole sequence.
Can the same square appear twice?
Yes, a square can appear more than once in a sequence, but never twice in a row, so every flash is clearly visible.
How can I improve my sequence memory?
Group the steps into chunks of three or four, picture the path as a shape or letter, say the positions to yourself (top-left, centre, bottom-right), and turn on the tones so you also remember a melody. Regular short practice sessions help more than long ones.
