About this game

Schulte Table is a grid of randomly-arranged numbers from 1 to N. Your job is simple: find the 1, tap it, then the 2, then the 3, and so on until the last cell. Your time is recorded, and a wrong tap adds a 2-second penalty. The classic format is a 5Γ—5 grid going from 1 to 25, but you can warm up on 3Γ—3 (9 cells) or push yourself with 7Γ—7 (49 cells).

It is one of the oldest tools in attentional training. Russian psychiatrist Walter Schulte introduced it in the 1950s as a way to measure attention span. Soviet-era cosmonaut training programmes adopted it; modern speed-reading courses still use it; competitive shooters and goalkeepers use it to train peripheral vision because the trick is to keep your eyes near the centre of the grid and locate numbers using the corner of your visual field rather than darting saccades around.

Tips for a faster time

First, sit at a normal reading distance from the screen β€” not so close that you can only see one cell at a time, not so far that the numbers are tiny. Second, before you tap "1", let your eyes settle near the centre of the grid. Third, try to keep your eyes still while you scan; the temptation is to look directly at every cell, but moving your eyes 25 times costs more than the few extra milliseconds it takes to spot the number with your peripheral vision.

A typical adult on a 5Γ—5 grid finishes in 30 to 45 seconds. Trained speed readers regularly clock 18 to 22 seconds. The published world record sits below 11 seconds β€” that is barely enough time to physically tap 25 cells, never mind locate them. If you want to improve quickly, do five 5Γ—5 runs back to back; you will notice the third and fourth attempts feel almost trance-like compared to the first.
