Capturing words isn't easy. Only the noblest and bravest of souls dare try. Many shrink back, fail, or give up. But you are not one of the many. You seek to capture words, and you will not be prevailed upon. It's you versus the world... Actually it's you versus thousands of squirrels running in circles to turn a crank that rotates a gear that drops a ball onto a lever that juices a server farm that powers an adaptive algorithm that quickly ramps up difficulty to match your skill, so LetterMarch is just as challenging for a college professor as it is for a first grader. Capture words, destroy superfluous letters, and conquer the world.
