A word appears. Type it. Another appears. Type that one too. Sixty seconds. As many words as your fingers can manage. The faster each word, the more points you score.
Typing speed correlates strongly with productivity in any keyboard-based job. Even casual typists can improve from 30 to 60 WPM with regular practice. Fast Fingers also trains motor planning and whole-word visual processing.
