🧠 Corsi Block Test: Measure Your Spatial Memory

Irregularly placed blocks light up one at a time. Remember the order, then tap them back exactly as they flashed — clear a length and the sequence grows by one. Devised by Philip Corsi in 1972 to measure visuospatial working memory, the longest sequence you reproduce correctly is your block span.

💡 How to play — Blocks light up one after another — watch the order, then tap them back in exactly the same sequence. Clear a length once out of two tries and the sequence grows by one. Two mistakes end the test, and your score is the longest sequence you reproduced correctly.
