Schulte Grid Game

The Schulte Grid is a classic attention training tool, originally invented by German psychologist Schulte. The game is simple: numbers are randomly filled in a grid, and the player needs to find these numbers in order.

This game helps to improve the following abilities:

Attention Concentration
Visual Search
Reaction Speed
Brain Flexibility

Reference Data

Here are the reference times for completing a 5x5 Schulte Grid for different age groups:

Age Group	Time Reference
7 ~ 12 years old	Less than 26 seconds is excellent, indicating top academic performance. 42 seconds is average, with a middle or lower class ranking. 50 seconds indicates significant issues, and the student may fail exams.
13 ~ 17 years old	Less than 16 seconds is excellent, indicating top academic performance. 26 seconds is average, with a middle or lower class ranking. 36 seconds indicates significant issues, and the student may fail tests.
18 years and older	The fastest time can be as low as 8 seconds. 20 seconds is average.

Reference data for a 4x4 Schulte Grid (children's version):

Time Reference
Less than 16 seconds is excellent.
26 seconds is average.
50 seconds indicates significant issues.

The Schulte Grid not only helps measure attention levels but is also an effective training method. It is commonly used by psychologists in therapy and training sessions.
Through dynamic practice, the Schulte Grid can exercise the visual nerve endings, improving the speed of visual orientation and search movements. It helps to develop attention concentration, allocation, and control, expand visual span, increase reading speed, and enhance visual stability, discrimination, and directional search ability.
As practice continues, the time required will gradually decrease. Beginners can start with a 9-cell grid and move to more challenging grids as they become more proficient. Those with wider visual fields and higher attention parameters can start with a 25-cell grid and, if interested, can create larger grids (e.g., 36, 49, 64, 81, 100, 121 cells) for further practice.
