How it works
Watch the path, then tap the same cells in order. Length grows; two misses ends. Corsi-style span can be normed on a real board. This 16-cell web grid is practice, not a clinical IQ.

❓ FAQ
Is this Corsi blocks?Corsi is a 9-block board with a published procedure. This is a 4×4 original lite.
Forward versus backward?This lite is forward only. Backward spatial span is a different load. Neither is an IQ index.
Why 4×4?To feel different from the 3×3 Corsi-style toy already on this site. Still not a normed board.
