Question 1

What is a Schulte Table (Schulte Grid) and how does it test peripheral vision?

Accepted Answer

A Schulte Table is a square grid filled with randomly placed numbers that you must find and tap in ascending order as fast as possible. It was developed by German psychiatrist Walter Schulte as a test of attention and visual search speed. Because the numbers are scattered, you cannot read them in a line; you have to take in the whole grid at once. The fastest players keep their eyes fixed near the center and detect targets with peripheral vision rather than scanning cell by cell. That is why the Schulte Grid is used by speed readers, athletes and pilots to measure and widen their useful field of view.

Question 2

What is a good time on a 5x5 Schulte Grid compared to the global human average?

Accepted Answer

Most adults finish a classic 5×5 Schulte Grid (numbers 1 to 25) in about 35 to 45 seconds on their first attempts. Players who practice regularly usually move into the fast range of 20 to 30 seconds within a couple of weeks. Elite performers and trained speed readers often finish in under 16 seconds. Teenagers and young adults tend to be quickest, while times gradually rise with age, mostly because of slower visual processing rather than weaker attention. Fatigue, screen size and distractions all matter, so compare your best time from several runs rather than one attempt when you judge your level against these benchmarks.

Question 3

How does daily Schulte Grid practice improve speed reading and ADHD concentration?

Accepted Answer

Speed reading depends on taking in several words per glance instead of one, which requires a wider useful field of vision and fewer eye jumps. Daily Schulte Grid practice trains exactly that skill: you learn to hold your gaze still and spot targets in the edges of your vision. It also demands sustained, selective attention, since every number must be found in order without losing your place. Many people with attention difficulties use short sessions as a focus warm-up. Five minutes a day is enough to see steady improvement. It is a helpful training exercise, not a medical treatment, and it does not replace professional ADHD care.

Question 4

How do Unlimited 25-Block Waves and the Active Play Timer work?

Accepted Answer

Level 1 is a 3×3 grid with numbers 1 to 9, Level 2 is 4×4 with 1 to 16, and Level 3 is the classic 5×5 with 1 to 25. From Level 4 on, each level adds 10 more numbers with no upper limit. The board never shows more than 25 tiles, so bigger levels are split into waves: Part 1 shows 1 to 25, Part 2 shows 26 to 50, and so on. The Active Play Timer only runs while you are searching. It starts when you tap the first number of a wave, pauses when the wave ends, and stays paused while reward videos play.

Question 5

What is Dynamic Shuffle (Gorbov-Schulte) Mode and how does it train working memory?

Accepted Answer

Dynamic Shuffle is a free mode that moves every remaining number to a new position after each correct tap. You can no longer remember where the next numbers were, so every search starts from scratch and relies purely on fast visual scanning. It is inspired by the Gorbov-Schulte test, a harder variant that uses two interleaved number sequences and forces you to switch attention between them while holding your place in each. Both versions put extra load on working memory and attention switching, because you must keep the current target in mind while the scene keeps changing. Expect slower times at first and faster improvement.

Question 6

Where should you look while solving a Schulte Grid?

Accepted Answer

Fix your eyes on the center cell and try not to move them. Every time your eyes jump from one spot to another, called a saccadic eye movement, you lose a fraction of a second and briefly take in almost nothing. Beginners dart around the grid hunting for each number, which makes them slow and tired. Experienced players keep a soft, steady central gaze and let their peripheral vision catch the next target, then tap it without looking directly at it. Start slowly, accept some mistakes, and practice keeping your eyes still. Over time the whole grid will feel readable in a single glance.
