Classic Concentration, is inspired by vintage game show 'Concentration' originally presented by Hugh Downs. Classic Concentration is based on the children's memory game of the same name. Two contestants match prizes in order to uncover and solve a rebus picture puzzle, for the chance to win a car in the "Winner’s Circle". Hosted by Alex Trebek, these episodes originally ran on NBC 1987 - 1991 and haven’t been on the air in over 20 years.
