Number Grid scatters numbers across a grid and asks you to find and click them in order. It is the Schulte table, a visual-search drill widely used in speed-reading and attention training. The scoring is pure time — nothing is hidden, everything is visible, and all the difficulty is in systematic search.
A grid of scattered numbers appears.
Find 1 and click it.
Continue in ascending order without skipping.
Every number stays visible throughout.
Your score is the total time to complete the grid.
Visual search efficiency and peripheral awareness. The drill trains you to widen your effective field so you spot the next number without a full scan.
Fix your gaze on the centre and use peripheral vision to find numbers. Scanning cell by cell is far slower.
Keep your eyes still between clicks. Each eye movement costs more time than people expect.
Look for the next two numbers at once so you are never searching from cold.
Do not use your finger to track. Following a pointer narrows your field to exactly what you are pointing at.
A grid of scrambled numbers found in order as fast as possible. It has been used for decades in attention and speed-reading training.
It improves at this task and at similar search tasks. Claims that it transfers to reading comprehension speed are not well supported — reading is limited by comprehension, not by eye movement.
Track your own improvement. Times depend heavily on grid size, so a published figure for a different grid would mislead.
Keeping them central and using peripheral vision is faster once you get used to it, which is exactly what the drill is for.
