     DESCRIPTION OF PREFERRED EMBODIMENT 
     Referring to  FIGS. 1 ,  2 ,  3 , and  4 , the present invention, designated as numeral  12 , includes a plurality of dominos cards  12  each having a rectangular polyhedron configuration with a top face ( 18 ) and a bottom face ( 20 ) with substantially the same dimensions. 
     Each card  12  is segmented into a top portion  14  and a bottom portion  16  having a top face  18  and a bottom face  20  respectively. The top portion  14  and bottom portion  16  both have a rectangular shape with a top face  18  and a bottom face  20  respectively surrounded by a plurality of sidewalls  25 . The peripheral edge  27  along the perimeter of the top face  18  of the top portion is recessed inwardly toward the center of the top face  18 . Centrally disposed is a window or opening  30  for viewing the selected mathematical operation showing below. The surrounding sidewalls  25  of the top portion  14  and bottom portion  16  are also recessed inwardly from the perimeter of the top face  18  and inwardly therefrom. 
     Encompassed between and centrally disposed therein is a means  35  for selecting a specific mathematical operation. In the preferred embodiment, the means for selecting a specific mathematical operation comprises a circular shape disc  37  with a rod  40  centrally disposed therein. Each mathematical operation is incorporated along the circumference of the disc  37 . The circular shape disc  37  is enclosed between the top portion  14  and bottom portion  16 . A small slot  42  allows the edge of the circular shape disc  37  to be exposed therethrough. In operation, a user rotates the circular shape disc  37  until the desired operation is displayed through the window  30 . 
     As shown the top face  18  and bottom face  20 , are divided into a left section  24  and a right section  26  with a movable mathematical operation  30  sign therebetween. Each section ( 24 ,  26 ) incorporates indicia means representing a number therein. Each section ( 24 ,  26 ) has a unique combination of a number with a variable mathematical operation sign therebetween. 
     The game is played in segments called hands. A hand consists of preferably four players with a hand of  12  cards each. Preferably it is recommended that not more than eight players take part in the game at any one time. The remaining dominos cards ( 10 ) comprise the deck which is used by the players to pull extra cards. 
     The game is designed to be played with all mathematical functions including addition, subtraction, multiplication, and division as shown on mathematical operation means  35 . Additionally, the game can be designed to work with algebraic functions wherein the indicia means incorporated on the face of the card can be letters. 
     Prior to beginning the game a numerical factor should be predetermined and agreed upon by the all the players. This numerical factor is used to determine the raw score of the current player. The game continues until a player reaches a predetermined negative or positive score. At that point the participants choose to either continue the hand until it plays out or end the game. 
     The game proceeds with selecting the number of domino cards in relations to number of players. Then, proceeding clockwise for the current player&#39;s a score is determined for each played card. Then, the raw score is determined by dividing the total score by the predetermined numerical factor thereby calculating the direct score for a particular play. 
     Each open ended card is computed individually. This individual computation is identified by the used of after each card has been played. The number provided by each producing a total sum of all cards in play as depicted in  FIG. 5 . 
     To play a card, it must match the numerical base value of the preceding card regardless of which tentacle alignment it would play against. If the current player has no available playing card, then each current player draws from the deck until a playable card is drawn. The first player to play out all of the game cards and have the highest score is the winner. 
     The complexity of the game can be varied as the players skills increased. The numbers on each section can be either negative or positive on the mathematical scale. 
     Referring to  FIG. 5 , there is shown an illustration of how the score is computed in the present invention. In this illustration, the computation proceeds as follows: (3+6)+(6×6)+(6−5)+(6/2). The total value is “49”. The computed value is (3+36+1+3)/3 wherein “3” is the predetermined numerical factor. Since “49” does not evenly divide by “3”, then there is no direct count computed in this case. Thus, the player does not obtain any points. The game can be adjusted to support fractions by agreement of the players. 
     In alternative embodiments, each card can be constructed to accommodate an electronic chips or chips. The electronic chips are programmed to select and digitally display upon each domino indicia means to support the mathematical game. In this embodiment as shown in  FIG. 1 , each domino can be incorporated with an electronic means ( 41 ) for controlling selection and display of an indicia means upon a first display means, a second display means and an operational display means. In this embodiment, the upper portion and lower portion have a face divided into a left section ( 24 ) and a right section ( 26 ) with an operational window ( 30 ) therebeteween. The first display means is incorporated upon the left section ( 24 ) for displaying a first indicia means. As illustrated number  7 , would be displayed upon left section ( 24 ). The second display means is incorporated upon the right section ( 26 ) for displaying a second indicia means. As illustrated number  6 , would be displayed upon right section ( 26 ). The operational display means is incorporated upon the operational window ( 30 ) for displaying a mathematical operation. As illustrated number “X”, would be displayed upon operational window ( 30 ). Each display means mentioned above can be a LED, LCD, Liquid Plasma or another suitable display means Thus, as illustrated the number  7 , number  6 , and “X” would be displayed utilizing LED&#39;s or LCD. The electronic means ( 41 ) can be a semi-conductor chip or chips having a processor ( 51 ), memory ( 52 ), and Input/output capability ( 55 ). The electronic means ( 41 ) can automatically control the display of the indicia means or provide the user an option to select the indicia means or mathematical operation to display through standard input means. The indicia means can be numerical or alphabetic for algebraic operations. The display means can be raised or in Braille to support blind persons. The input means can be keyboard like, handwritten recognition or voice recognition. The input means can be implemented through a small keyboard upon peripheral edge  27 . Alternatively, an input communication port can be added into peripheral edge  27  near electronic means  41  and a removable keyboard can be connected to domino card  12 . The electronic means comprises a random number generator software ( 53 ) that programs the processor to randomly compute a left indicia means. a right indicia means, and a mathematical operation.
