Memorize a pattern of filled cells on a grid, then recreate it from memory. Based on the Visual Pattern Test (Della Sala et al., 1999), a validated measure of visuospatial short-term memory.
Study the pattern
A grid appears with some cells filled in purple. Study it carefully — the pattern will disappear after a few seconds.
Recreate it from memory
Tap the cells you remember being filled, then press Submit. Take your time — there is no time limit during recall.
See your result
Green cells = correct, amber = cells you missed, red = cells you added by mistake. Aim for 75%+ accuracy to keep your lives.
Complete 5 rounds without running out of lives. Each round uses a randomly generated pattern.
