Path Trace
A path glows across the grid, one step at a time. Retrace it in the same order.
How to play
- Watch the path light up step by step
- Retrace it by tapping the cells in order
- A wrong cell costs a life; you have 3
- Each success adds a step
What it trains
Spatial. This is a walking version of the Corsi block-tapping task from 1972, still used in neuropsychology to measure spatial span. Typical adults manage sequences of 5 to 6 blocks. Paths are kinder than random blocks because each step constrains the next, and your brain happily exploits that structure.
Corsi, 1972; Berch et al., 1998 review.
One honest tip
Trace the path with your eyes during playback, like dragging a finger you do not have.
