An educational game system consisting of three or more individual decks of cards, and, in some embodiments, an extra set of cards used for special situations to be described hereinafter, and consisting of at least two individual games. The first of the two games is for developing a working knowledge of a set of mathematical (e.g. arithmetic, propositional, lingual) relations, and can be played by two to a given number n of players using one deck, up to 2n players using two decks, up to 3n players using three decks, etc. The second game is a game of skill and chance, played using all of the decks, which is also a means of separating the decks from each other. |

DETAILED DESCRIPTION This invention presents a given number of decks of cards, each card having one side which is identical with respect to all other cards in its own deck, but unique with respect to all cards of other decks, and the other side showing a value pair and/or a relation pair (as previously defined).
Also included may be one extra set of cards, each card having one side bearing some type of punctuation (as defined hereinafter), and the other side identical with respect to all other punctuation cards, but unique with respect to all nonpunctuation cards.
Punctuation for purposes of this specification and the following claims is defined as any words, symbols, or characters without which the same concept could be expressed by position, but which are used anyway through choice or convention.
The value/relation/punctuation side of the cards should be designed so that the following specifications are met: (1) Any value or relation card should be readily identifiable from at least two opposite corners.
(2) Every value card should have its value printed in two colors, going in opposite directions on the card.
(3) Every relation card should use the same two colors, having each of its relations (even if they are the same relation) printed in one color and one direction on the card.
(4) Every punctuation card should use the same two colors, or just one of the two, having its punctuation printed in as many directions.
(5) It should be possible to line up any two cards in such a manner that one color and direction line up on one side, and the other color and direction line up on the other side.
(6) The only exception to the above specifications are the following: (A) In an embodiment in which all statements formed in one direction are identical in meaning to the statement simultaneously formed in the opposite direction, only one color need be used (for both directions).
(B) In an embodiment in which all symbols representing values have meanings which remain the same when the symbol is rotated 180 degrees (e
