Based on the Sony Pictures Television format, the classic game show CHAIN REACTION - which originally debuted in the 1980s - features two teams competing against one another to complete chains of words, after the first and last words of the chain are revealed. Each word in the chain is related in some way to the word directly above and below it. By making inferences based on the revealed words and the revealed letters in incomplete words, contestants try to fill in the word chains to win money.
