Proof It!
Find the word (or punctuation) which contains a mistake, and then type in the correction. Work quickly and accurately for bonus points.


Which Word?
Read a sentence that has one word left out, and select the word which most appropriately fits the context of the sentence. This game focuses on pairs of words which are often used incorrectly.


Alphabet Soup
Two letters have been left out of a word. Fill in the missing letters in as many ways as possible to create valid words. Try to gain speed bonus points, but avoid making too many guesses, or you'll lose accuracy points.
