How do you get high scores?

Count on it taking about 8 completed puzzle grids to get 100 points, so about 80 completed to get 1000 points. It really depends on how quickly you complete each word puzzle. Many people can get 500 plus points in a steady hour of play, so count on it taking 2-3 hours of steady play get 1000...depending on how quickly you solve each one. I am reasonably quick for the first hour or two (not as fast as some), but can’t keep it up, so I usually reach 1000 in a little under 2 hours.
