Working memory

Pincode Game

A timed memory drill that trains digit span and mental manipulation. A sequence flashes one digit at a time, then you type it back: in order, reversed, or sorted low to high. The sequence grows as you get them right, so it always sits at the edge of your memory, or you can cap it and drill one length until the technique sticks. A staple of trading-firm cognitive assessments.
