To unlock the mystery of The Cypher players must carefully explore three different time paths: the middle ages, the summer of 1900 and the final weeks of the 20th century. They explore ancient ruins, examine historical documents, news clippings, forensic evidence, hack into secret computer files and uncover clues to a startling mystery. Each week new evidence emerges and new locations are revealed. In the final episode, players race against time, an evil villain and each other to solve the mystery before time runs out. The Cypher became a runaway success for Sierra's World Opponent Network (WON.net) with over 2 million registered players and 2.5 million page views per month.
