The rules of the game are simple. You are given a dictionary definition and the first letter of the word and you must type in the rest, while a timer is going. You keep going until you miss or skip a certain number of words or time runs out. It is incredibly addicting, but so educational, you won't care.
Knoword is great for any age from teenagers on up. It would be fun for teens and parents to take turns playing and compare scores. In addition to vocabulary and spelling, you are also advancing your analytical and typing skills. You can become a member (free, and optional) of Knoword. If you do, you get to have your play ranked against other members and can suggest new words for the game.
If you don't believe that an educational game can be so fun and addictive, go try Knoword now. When you finally come up for air, please come back and comment and let us know what you think of the game.
