Player one types the first word of a sentence into the computer. Player two types the second word. The other players enter new words on their respective turns. If a player sees an opportunity to end the sentence with a word, he or she may do so and follow it with a period. No more words can be entered following the period.
Players use the text editing keys to insert words inside of the sentence.
The sentence must continue to be grammatically correct. The first player to extend the sentence to the end of the matrix is the winner.
