What a Schulte table is
A Schulte table is a square grid of numbers in random positions. You find them in ascending order, as quickly as you can. The classic version is five by five, 1 to 25. It is named after the German psychiatrist Walter Schulte and has long been used as a simple attention and visual-search exercise.
How to get more out of it
- Start small. Try 3×3 to learn the feel, then 4×4, then 5×5.
- Look at the middle. The traditional instruction is to keep your eyes on the centre square and find the numbers with the edges of your vision. It is harder than it sounds.
- Compare like with like. A 5×5 time only means something next to another 5×5 time, on the same screen.
What your time does and does not mean
Your time will usually drop over the first few tries. That shows you are getting better at this table. It is not a measure of intelligence, it is not compared with anybody else, and it is not a medical or diagnostic test.

Attention Age is an iPhone app with a five-minute test built from three timed tasks: tap the signals and skip the decoys, judge the middle arrow, and follow moving shapes. You get a 0–100 Attention Index and five category scores, each explained in plain language.
A weekly re-test uses the same tasks so you can compare fairly, and one 20-second Daily Signal is free every day. No account. Your results stay on your iPhone.

Questions
How do you play a Schulte table?
Tap the numbers in ascending order, starting at 1, as fast as you can. The timer starts on your first correct tap and stops on the last number.
What is a good Schulte table time?
There is no official standard, and times depend on the grid size, your screen and how much you have practised. The useful comparison is your own earlier time on the same grid.
Does the Schulte table improve attention?
Practising it reliably makes you faster at Schulte tables. Whether that carries over to other tasks is not something this page can promise.
Is this a medical attention test?
No. It is a practice game. It cannot diagnose anything.
