A passage is drawn at random from a set of seven and shown above the input box. Type it out one character at a time; each character you get right turns green and the cursor moves on. The sixty second clock does not start until your first keystroke, and the run ends when the clock reaches zero or you finish the passage.
Words per minute uses the standard five characters to a word: correct characters divided by five, divided by the minutes elapsed, updated once a second. Accuracy is correct keystrokes as a percentage of all keystrokes, so a wrong key costs accuracy permanently even after you fix it. Best WPM keeps the session high. Note that finishing the passage early still has the final WPM worked out over the full sixty seconds, so it reads lower than the live figure.
The run stops and your result is recorded, but the WPM is calculated across the full minute rather than the time you took.
Yes. New Text loads another of the seven passages at any time and resets everything except Best WPM.
Yes. On a touch screen the game shows on-screen buttons, and games played with a mouse work by tapping.
