What is a Schulte Grid?

A Schulte grid (or Schulte table) is a square grid filled with randomly arranged numbers. Your task is simple: tap or click each number in ascending order — 1, 2, 3… — as quickly as possible. The catch is that your eyes should stay fixed on the center of the board. Finding each number using your peripheral vision, not by scanning, is the whole point.

Originally developed as a psychological assessment tool for measuring attention and processing speed, Schulte grids became widely used in sports science, pilot selection, and cognitive rehabilitation. Today millions of people use them as a daily mental workout — 5 to 10 minutes a day can measurably improve reading speed, visual field, and focus.

Health & Performance Benefits

  • Peripheral vision — trains your brain to perceive information away from the center of gaze, expanding your functional visual field.
  • Processing speed — repeated practice reduces reaction time and the time needed to scan and categorize visual information.
  • Working memory & attention — keeping track of the next target while scanning strengthens attentional control and working memory.
  • ADHD support — the structured, immediately rewarding nature of the task helps build sustained attention and reduce distractibility.
  • Cognitive maintenance for seniors — regular use supports neuroplasticity and helps maintain processing speed as we age.
  • Athletic training — used by professional teams to improve court vision, situational awareness, and decision speed. Standard selection test for pilots and drivers.

Six Game Modes

We offer six difficulty modes to keep training fresh. Normal is the classic experience — numbers stay visible after tapping. Easy removes the cell background on each correct tap so the found numbers float in space. Blind removes the number itself, leaving an empty cell. Blind + Easy removes both — the found cells simply disappear. Mix and Easy Mix shuffle the remaining numbers after every tap, forcing you to relocate targets constantly — the hardest training for peripheral processing.
