Chain Reaction is based on the popular television game show of the same name. Players must try to guess words based on their relationship with the previous or following word. Players may request to be given letters of the words to help them solve the word. Each letter given by the computer, and each wrong guess reduces the players score. Therefore, the object is to guess all the words in the chain with as little help as possible, and with as few incorrect guesses as possible. The number of games per day is set by the system operator. Callers have the option to make up missed turns from previous days. The game is reset each month automatically. No need to run any maintenance routines.
