Working memory

Grid Recall

A spatial working memory drill. A pattern of cells flashes on a 4x4 grid, the grid is masked, and you click the pattern back from memory. Red decoy cells try to sneak into your answer, and the pattern grows while you keep getting rounds right. Twenty rounds, adapting to the span you can hold.

Mode

Sequential

Twenty rounds of pattern recall: the grid flashes a set of blue cells, then you click them back from memory. Half the rounds add red decoy cells to keep out of your answer. The pattern grows while you get rounds right.

Upgrade to unlock Sequential mode.

Session

20 rounds, one pattern each. Two correct rounds grow the pattern by one cell; a miss shrinks it by one, so the drill settles at the size you can hold.
