Alternate connecting numbers and letters in random designs. The faster you go the more points you get.

Connectors from ProCogny is fun game that requires keeping two sequences in mind at the same time. The technical term for this ability is alternating tasks. Players will connect a series of dots in random patterns by alternating between numbers and letters. Click the right ones to get points, lose points by clicking them in the wrong order. You may find yourself going faster as you progress, and the levels get more complex with more and more dots.
