Speed and Precision
A grid of scrambled numbers and one simple goal: click them from 1 upward as fast as you can. Schulte tables train visual search, attention span and steady focus.

Example
In this 3x3 example, 1 and 2 are found. The next number to find is 3.
Every number gets its own split time, so you can see where you slowed down.
Schulte tables have been used for decades in attention research and speed-reading courses.
The grid scales to your screen. The 7x7 table works best on a larger display.
Your times stay in this browser. No account needed.
Total time, errors, average per number and a chart of every split.
Start on 3x3 to learn, train on 5x5, and push yourself on 7x7.
The main score: the time from the board appearing to finding the last number.
How it is calculatedSum of all split times, in seconds
Clicks on a number that was not the next one.
How it is calculatedCount of wrong clicks
Your typical search time per number, useful for comparing grid sizes loosely.
How it is calculatedTotal time divided by numbers found
How long each number took. Long splits show where your scan broke down.

These bands are site-defined guidance for adults on a desktop computer or a recent phone. They are not population norms and not a diagnosis.
| Band | Range | What it means |
|---|---|---|
| Excellent | below 5 s | Instant recognition. |
| Good | 5-7.9 s | Quick and smooth. |
| Average | 8-11.9 s | A typical first result. |
| Needs practice | 12 s or more | Try scanning in rows. |
| Band | Range | What it means |
|---|---|---|
| Excellent | below 20 s | Strong visual search. |
| Good | 20-29.9 s | Better than many first sessions. |
| Average | 30-44.9 s | A common range. |
| Needs practice | 45 s or more | Practice brings fast gains here. |
| Band | Range | What it means |
|---|---|---|
| Excellent | below 60 s | Outstanding for a large grid. |
| Good | 60-89.9 s | Steady and efficient. |
| Average | 90-129.9 s | A typical result. |
| Needs practice | 130 s or more | Build up on 5x5 first. |
The tables are named after the German psychiatrist Walter Schulte, who used number grids to study attention in the twentieth century.
They later became popular in education and speed-reading courses, especially in Eastern Europe.
Finding numbers in order combines visual search, working memory for the next target, and sustained attention across the whole grid.
Your speed depends on how well you scan without losing your place.
Speed-reading teachers suggest keeping your eyes near the center and spotting numbers with peripheral vision. With practice, many people find they move their eyes less.
Whether this transfers to reading speed is debated. The table itself, however, clearly improves with practice.
Grid size has the biggest effect, so only compare times on the same size. Screen size, marking found numbers, and fatigue matter too.
Most people improve quickly over the first few sessions, then more slowly. Track your median over a week rather than a single best.
Each bar in the chart shows how long one number took to find. Tall bars point to numbers that were hard to spot, often because they sat in a corner or near a similar-looking number.
Over several sessions you may notice that your bars become more even. That usually means your scanning has become more systematic.
With marking on, found cells are shaded and the search area shrinks as you go, which makes the last numbers easier. With marking off, the grid stays the same throughout, which is closer to the paper version.
Both are valid. Choose one and keep it, so that your history compares like with like.
Your first table of the day is often the slowest. Eyes and attention need a moment to settle into the scanning rhythm. A quick 3x3 table before your main 5x5 session takes only a few seconds and usually makes the recorded result more representative.
Over a week, compare your median rather than your single best time, because a lucky layout can produce an unusually fast result.
Number search tasks are used to study attention, visual search and processing speed.
Teachers use printed Schulte tables as short focus warm-ups at the start of a lesson.
A two-minute daily habit that gives a clear, trackable number.
Similar tasks appear in some assessments. This online table is a training game, not a diagnostic tool.
Rest your gaze near the middle and let your peripheral vision find the next number.
Silently repeating the target number keeps it active while you scan.
A wrong click costs only a moment. Panic costs more.
Pick one grid size for a week so your progress is easy to see.
It is a grid of numbers in random order. You find and click them in ascending order as fast as you can.
After a countdown the grid appears and the clock starts. You click each number in order. The clock stops on the last number.
A 3x3 table takes a few seconds, a 5x5 table usually 20 to 45 seconds, and a 7x7 table one to two minutes.
Yes. Press P, use the pause button, or switch tabs. The clock stops while paused. Only completed tables are saved.
Any modern browser. The 7x7 table is best on a tablet or computer screen.
Total time is your main score. Errors show how often you clicked the wrong number. Split times show where you lost time.
For 5x5, under 20 seconds is Excellent and under 30 seconds is Good on this site. These are site guidance bands.

It is often used in speed-reading courses, but evidence that it makes reading faster is limited. It is best treated as an attention and visual search exercise.
The total time only means something when every number has been found, so a partial table cannot be compared with complete ones.
Results depend on age, device, sleep, language, mood and practice. Average several sessions before drawing conclusions. This is not a medical or psychological diagnostic tool.
It takes about a minute. Your results stay private in this browser.
