About this game
Designed by Philip Corsi in 1972, the Corsi Block-Tapping test measures spatial working memory — distinct from verbal working memory (Digit Span). Average adult span is around 5 blocks.
In each round, blocks light up in sequence; you tap them in the same order. Span grows by 1 each correct round, up to 9 blocks.
