A two-minute focus drill with a clear start, a clear end, and a score. Free to play below — no sign-up. It is not a diagnostic tool and not a treatment.
No account? It takes less than 10 seconds.
This is a focus exercise, not a medical device. It cannot diagnose ADHD, it is not a treatment, and your time on it says nothing about whether you have the condition. If you're looking for a diagnosis or considering changes to how you manage ADHD, that conversation belongs with a qualified clinician.
A Schulte Table asks you to find numbers in order while keeping your eyes fixed on the centre of the grid. It trains one narrow, measurable thing: how quickly you can locate a target in your visual field without hunting for it. That skill is real and it is trainable.
What it does not do is generalise. The research on brain-training transfer — the idea that practising one narrow task improves cognition broadly — is mixed at best, across the entire category. Anyone selling you a focus game as an ADHD intervention is ahead of the evidence.
The reason it still shows up in ADHD discussions is more practical than clinical. A round takes seconds. It has a defined beginning and end. Every tap gives feedback. The score is unambiguous, so there's no ambiguity about whether you did the thing. Those are properties that make a task easy to start — and starting is usually the hard part.
Keep it to two or three minutes
About five rounds on a 4×4. Stop while it still feels easy to continue — that's what makes you willing to come back tomorrow.
Use it as a starting ritual, not a workout
The most common report is that it's useful immediately before something you're avoiding. A short task with a guaranteed finish is an easier on-ramp than the thing itself.
Start on the 4×4, not the 5×5
Short rounds beat impressive ones. Move up only when the smaller grid stops feeling demanding.
Watch accuracy, not just time
Rushing to a fast time with several misclicks is the opposite of what you're training. A clean slow round is worth more than a messy fast one.
Expect bad days, and don't read into them
Times swing with sleep, stress, caffeine and time of day far more than most people expect. One slow session is noise, not a signal.
No. Schulte tables have a history as a clinical attention-assessment instrument, used by a trained professional alongside other measures — that is not the same as a diagnosis, and it is certainly not something a website can do. A slow or inconsistent time here tells you nothing about whether you have ADHD. Many people without ADHD have slow times, and many people with ADHD have fast ones. If you're seeking a diagnosis, that requires a qualified clinician.
Honestly: the evidence for broad transfer is weak, and that applies to the whole brain-training category rather than this exercise specifically. What is well supported is that you get better at what you practise — so you should expect to improve at fast visual search and at holding attention on a short, structured task. Some people find that a two-minute drill with a clear start, end, and score is a useful way to begin a work session. That's a real benefit, but it's a behavioural one, not a treatment effect.
A few properties line up well: rounds are very short, so the task ends before attention has to be sustained through boredom; there's immediate feedback on every tap; the score is unambiguous; and the difficulty adapts, so it rarely sits in the demotivating zone of far-too-easy or far-too-hard. None of that is ADHD-specific — those are just properties of a well-designed short task — but they're the properties people commonly report struggling to find in longer focus exercises.
Shorter than you'd think. Two to three minutes, or roughly five rounds on a 4×4. The point is to finish while it still feels easy to continue. Long sessions turn a task you'll come back to into one you'll avoid, which is the failure mode that matters most for building any daily habit.
The 4×4. It's about 8–15 seconds a round, which is short enough to complete before frustration sets in, and it lets you get several rounds into a couple of minutes. Move to the 5×5 when the 4×4 stops feeling demanding — not before.
It's a free, ad-light game with no chat, no social features, and no purchase required to play, so there's little to object to. Start on the 3×3 or 4×4, keep sessions to a few minutes, and treat it as a game rather than therapy. Anything concerning a child's ADHD care should go through their clinician.
