What Is Brain Training?
Brain training is the practice of exercising specific mental skills with structured, repeatable tasks.

Why Train Your Brain Here?
- One skill at a time. Each subcategory isolates a single ability, so you know exactly what you are training and can track it separately.

- Short sessions are enough. Five minutes of focused daily practice beats one long weekly session for building cognitive habits.
- Progressive difficulty. Levels add targets, speed and complexity only as your accuracy proves you are ready.

Brain Training FAQ
Is brain training on this page free?
Yes. Every exercise in all six subcategories runs in your browser and is free to play with no sign-up required.
Which skills can I train?
Working memory (N-Back, sequences), attention (Schulte Grid, Stroop), deduction (logic puzzles), reaction speed (CPS and reflex tests), perception (colour and time) and spatial reasoning (mental rotation and symmetry).
How long should I train each day?
Five to ten minutes of focused daily practice is the recommended dose. Consistency matters more than session length.
How do I know I am improving?
Every game records a concrete metric — best time, score or level — so you can compare today's result with last week's on the same task.
The training library grows with the site: each new cognitive game joins the subcategory that matches the skill it trains.
