Card Sharks is an American television game show created by Chester Feldman for Mark Goodson-Bill Todman Productions. Based on the card game Acey Deucey, the game has two contestants compete for control of a row of oversized playing cards by answering questions posed by the host and then guessing if the next card is higher or lower in value than the previous one. The concept has been made into a series four separate times since its debut in 1978, and also appeared as part of CBS's Gameshow Marathon. The show originally ran on NBC from 1978 to 1981 with Jim Perry hosting; a revival ran from 1986 to 1989 on CBS with Bob Eubanks as host, accompanied by another version in syndication with Bill Rafferty. Gene Wood was the announcer on these three versions. Another syndicated revival aired from 2001 to 2002 with Pat Bullard as host and Gary Kroeger as announcer. All versions of the show had various female assistants to handle the playing cards.
