Let's be clear up front

It's not "right-brain training."
There's no such thing.

You might have heard of "left-brained" and "right-brained" personalities. Brain science has retired that idea — a large 2013 study found no such whole-brain type. So Right Brain isn't "right-brain training"; it's a set of playful ways to practise the broad, open, present mode of attention.

The name is an evocative metaphor. The science is real — and we keep the two clearly apart.

A gym for the wide-angle mind

One open skill, thirty ways to practise it.

The whole, not the parts

Each game rewards grasping a scene's gist — its average, its flow, its balance — instead of fixating on one loud detail.

Real perception science

Ensemble perception, Gestalt grouping, global motion, scene gist — every game maps to a peer-reviewed phenomenon.

A two-minute reset

Glance, sense the whole, choose. Short adaptive sessions that meet you at your level and widen your lens by the end.

How it works

Glance. Sense the whole. Resist the loud detail.

  1. 1

    A whole flashes by

    A scene appears for a brief, comfortable glance — flicker-safe by design (WCAG 2.3.1).

  2. 2

    You read its gist

    Sense the average, direction, balance, or pattern — the whole, not the standout.

  3. 3

    You resist the lure

    Each round hides one salient detail built to pull your eye. Catching the whole anyway is the practice.

  4. 4

    It adapts to you

    Difficulty tunes to your edge. Choose your pace and length in Settings — or tap Surprise me.

We grade by the evidence — a real mix of Strong, Moderate, Early and Contested. When the science is still debated, we say so.

Grounded in evidence

Science-First isn't a slogan. It's in the build.

An evidence label on every game

Strong, moderate, early, or contested — each game shows its grade and its peer-reviewed sources in plain sight.

No "brain score"

We show practice consistency and how you feel before and after — concrete, measurable signals, never a single invented number.

A claims linter

A check in our codebase blocks medical claims and debunked neuro-myths from ever reaching a screen.
