Abstract: Improved flash cards for teaching and practicing the game of blackjack. Each flash card has two playing situations presented in separate sections (10 and 23) on its front side, in opposing orientations and at opposing ends of the card. In each section, the playing cards held by the player are represented as two or more overlapping images (11 and 12) of portions of playing cards. The dealer's card is a smaller image (16) of a playing card in perspective, within a frame (14) which overlaps the image of one of the player's cards. The recommended action (42) for a player to take when presented with each situation and the rule (44) governing how to play in each situation are printed in similar sections (40 and 50) on the back of each flash card. Identifiers (18and 46) appear on each side of the flash card to indicate a group of flash cards to which the card belongs, and the sequence of the card within that group.
