Passive learning system for international code flags or signaling flags

Abstract: A passive learning system is provided herein. The passive learning system may comprise a plurality of cards which define a deck of cards. Each card in the deck of cards may define a front surface and a back surface. The front surface may have a unique card identifier, corresponding flag indicia and corresponding flag descriptor indicia. The unique card identifier may be typical of a conventional deck of cards (e.g., ace of spades, queen of hearts, etc.). The deck of cards may be used to play any game such as poker or blackjack, etc. As the participant plays the card game, the participant may be dealt random cards having random unique card identifiers, flag indices and corresponding flag descriptor indices. The participant may simultaneously learn to recognize the signaling flags and their meanings in a fun low stress environment. (end of abstract)
