Best level by mode and difficulty
Sequence, Pattern, Easy, Standard, and Hard keep separate best levels because the task changes.
Free Browser Tool
Choose Sequence mode to watch cells one by one and replay them in order, or Pattern mode to see all target cells for 3 seconds and then select them from memory.
Pick Easy, Standard, or Hard difficulty, review your best level, and compare recent sessions stored only on this device. This is a practice task, not a medical or cognitive diagnostic test.

The History button keeps recent visual memory sessions on this device so you can compare your own practice without creating an account.
Sequence, Pattern, Easy, Standard, and Hard keep separate best levels because the task changes.
The last 20 sessions per mode and difficulty show best level, longest sequence, mistakes, accuracy, and duration.
Visual memory history stays in browser storage and is not uploaded to Quartenson analytics or backend systems.
For fair comparison, use the same mode, difficulty, device, and input method when checking whether your level is improving.
Use this tool when you want a short sequence-recall task that is easy to repeat and compare.
Useful for practising ordered positions or short whole-pattern recall rather than finding one target.
Good for quick practice sessions where the goal is to stay attentive for a growing pattern.
Best for users who want a lightweight local record without accounts or cloud sync.
Each browser tool includes a result benchmark below the trainer. After a completed session, you can compare the current setup with anonymous community completions or sessions saved on this device. Use it as practical context, not as a medical, safety, or diagnostic score.
Benchmarks are grouped by matching tool settings, such as grid size, mode, difficulty, trial count, device context, and input method.
Community charts use completion metrics only. They do not include account details, email, or your local progress history.
The local view uses sessions stored in this browser, so you can compare repeat practice without uploading those local results.
The task has two modes. Sequence mode asks you to remember the order of highlighted cells. Pattern mode shows all target cells together for 3 seconds, then asks you to select the remembered cells without order.
If you complete the full sequence or pattern correctly, the next level becomes longer. If you miss a cell, the session ends and your best completed level is saved locally.
This tool is for short visual-memory practice and self-comparison. It does not diagnose memory, attention, or cognitive ability.
A useful result combines level, sequence length, mistakes, and accuracy.
| Metric | What it means |
|---|---|
| Best level | The highest level you completed before the session ended |
| Longest sequence | The longest pattern you successfully replayed |
| Accuracy | Correct clicks compared with all replay attempts |
| Mistakes | Missed cells that ended the session |
Do not compare Pattern results directly with Sequence results, or Hard results directly with Easy results. They use different memory pressure.
Start with the difficulty that lets you complete several levels cleanly before increasing the grid size.
A 3x3 grid for learning the task and building confidence with shorter patterns.
A 4x4 grid for normal practice with a balanced amount of visual search and memory load.
A 6x6 grid for denser position recall once Standard feels stable.
If your mistakes appear early, lower the difficulty and rebuild clean sequence recall first.
Avoid clicking early. Wait until the preview ends, then replay the cells in the required order or set.
Mentally group positions by rows, corners, or simple shapes instead of memorizing isolated dots.
Compare the same difficulty on the same device and input method.
A tired session can make your level look worse without telling you much about progress.
Short answers about the browser-based visual memory trainer.
A visual memory test asks you to remember visual information, such as positions in a grid, and recall it after a short delay. This browser tool uses ordered sequences, 3-second pattern recall, and progressive levels.
No. It is a recreational practice tool for self-comparison. It does not diagnose memory, attention, cognitive ability, or any health condition.
There is no universal good level because results depend on difficulty, screen size, device, input method, fatigue, and practice. Compare your own sessions with the same settings.
Yes, locally on your device. It can keep the last 20 sessions per mode and difficulty plus your best level. The history is not synced or uploaded and can be cleared from the History modal or browser storage.
After a completed session, the benchmark compares the current tool settings with matching completion metrics. The Community view uses anonymous aggregated results, while This device uses sessions stored locally in your browser.
Quartenson uses only the result metrics needed for comparison, such as time, accuracy, mistakes, level, or clean trials. It does not use account details, email, or local history for the community chart.
A benchmark needs enough matching completions for the exact setup. If there is not enough data yet, the chart may be hidden until more matching results are available.
