What Are Prefrontal Games?

The prefrontal cortex, right behind your forehead, is the brain's chief executive. It powers the executive functions — setting goals, suppressing impulses, holding and processing information in mind, and switching nimbly between rules. Cognitive science groups these into three core components, each with classic training paradigms that have been used for decades — and this collection turns all of them into instantly playable games:

The Schulte Grid (attention and visual scanning) and Memory Matrix (spatial working memory) round out the collection as ideal companions.

How to Train Most Effectively

  1. Short and frequent: 5–10 minutes a day beats a weekend marathon — brains consolidate through spaced repetition.
  2. Rotate the trio: alternating inhibition, memory and flexibility is more balanced than grinding a single game.
  3. Stay in the challenge zone: adaptive difficulty keeps you at "reachable but effortful" — the sweet spot for progress.
  4. Sleep on it: executive-function gains consolidate during sleep; late-night cramming is half as effective.

よくある質問

Do prefrontal games really exercise the brain?

Their prototypes (Stroop, N-back, task switching) are classic experimental paradigms that cognitive science has used for decades, reliably training each executive-function component. Treat them as brain fitness — regular practice yields steady gains.

Who are they for?

All ages: students sharpen focus and working memory, professionals train task-switching and interference resistance, and older adults stay cognitively active. Rotate the three games daily for 5–15 minutes.

How long should I train each day?

5–15 minutes is ideal — each game takes 1–2 minutes per round, so two rounds of each fits perfectly. Stop when you notice your mind wandering; executive training needs an awake brain.

Are scores and progress saved?

Yes. Your Stroop best, current N-back level and best N, and Task Switching best score are stored locally in your browser and restored automatically. Clearing browser data resets them.
