Besides a time limit, the game also has other difficulty features. The box jumps around without any clear pattern, thus throwing off your rhythm. It also chooses words at random. Often, you must type short and long, complex words in succession. The game measures your top score and your accuracy rating in the end.

The exercise is ideal for students who are typing for the first time. Adults can also benefit by improving both their typing speed and accuracy. Remember, the key to better scores is through practice.
