A card viewing device has a housing having opposed first and second side walls, opposed front and rear walls, a card-accepting entranceway in a lower portion of the front wall, a viewing aperture in an upper portion of the rear wall, and an optical system within the housing for projecting an image of a portion of at least one card received within the device through the entranceway through the viewing window for observation by a user. The device is particularly adapted to allow private viewing of playing cards lying face-down on a playing surface, allowing the user of the device to view the card faces without lifting the cards off the playing surface or otherwise making them viewable by others.
