🧠  How to Train Working Memory in 4 Steps

1) Start with Number Chunking (2–3 min)

Warm up by memorizing short digit strings, then typing them back exactly. Use chunking: split long numbers into small groups (e.g., 173905 → 17 · 39 · 05).

Try: Number Memory — increase one digit at a time, reset gently after a miss.

2) Add 1-Back Attention (2–3 min)

1-Back tasks train you to compare the current item with the previous one—a light version of more intense N-back drills. Focus on calm, consistent responses over speed.

Try: 1-Back Letters — start at 0.9s pace, then move to 0.75s as accuracy stays ≥90%.

3) Train Visual Recall (2–3 min)

Visual memory benefits from quick flips and targeted search. Alternate between pure recall and focused search so you practice both storing and selecting information.

• Recall: Matching Pairs — flip methodically, remember card positions.
• Selective attention: Visual Search — find the odd tile fast.

4) Track, Tweak, Repeat

Keep sessions short and consistent. Aim for accuracy first (≥90%), then nudge speed or difficulty. Most games store best scores locally in your browser (localStorage), so you can see progress.
