How to Play

1. Watch – Gray squares will briefly light up in a sequence (one by one).
2. Repeat – Click the squares in the exact same order.
3. Progress – Each correct round adds one more step to the sequence.
4. Fail? – The game ends. Try to beat your longest sequence!

Why Train Spatial Memory?

Spatial memory is crucial for:

• Navigation – Remembering routes and locations.
• STEM learning – Visualizing geometry, diagrams, and 3D structures.
• Everyday tasks – Packing, organizing, and recalling where things are.

This grid‑based task is a digital version of the classic Corsi block‑tapping test, a widely used neuropsychological assessment.

Tips for Improvement

• Chunking – Mentally group squares into patterns (L‑shape, diagonal).
• Verbal coding – Silently name positions (e.g., “top‑left, center”).
• Pacing – Don’t rush; accuracy is more important than speed.
• Gradual increase – Start with 3×3 and short sequences, then increase grid size.

Difficulty Levels

Initial sequence length is always 3. After each correct recall, the sequence grows by one.
