Schulte Table: Number Search
NumberRushV scatters numbers across a grid and asks you to tap them in ascending order against the clock. It is a Schulte table, a long-standing exercise for peripheral vision and visual search.
How to play NumberRushV
- A grid appears with the numbers placed at random.
- Tap them in ascending order: 1, then 2, then 3, and so on.
- The clock starts when you tap 1, not when the grid appears, so you can look before you begin.
- A wrong tap adds a one second penalty.
- The clock stops on the last number. Each grid size keeps its own best time.
How scoring works
Your score is the elapsed time from tapping 1 to tapping the final number, plus one second for every incorrect tap along the way. Lower is better. Best times are stored per grid size, because a 5x5 and a 7x7 are not comparable, and improving on one does not carry over to the other.
Three ways to score better
- Hold your gaze near the middle of the grid and find numbers without moving your eyes. That is the actual exercise.
- Do not scan line by line. It feels systematic but is slower than letting the number appear in peripheral vision.
- Accuracy beats frantic tapping. A one second penalty wipes out several fast finds.
Common questions
What is a Schulte table used for?
It is a classic drill for widening the span of visual attention and speeding up visual search. Its usefulness is as an exercise, not as a diagnostic of anything.
When does the timer actually start?
On your first tap on the number 1. You can study the grid for as long as you like before that without it costing you anything.
Why keep separate records per grid size?
A larger grid is a different task, not just a longer one. Pooling the times would make a good 5x5 look like a poor 7x7.
