Simplified closable type game board device for basic symbol and alphanumeric recognition

A Nim game device comprising:

• a rectangular closable type playing board, the rectangular closable type playing board including a rectangular lid and a rectangular bottom board which are both of congruent length, height, and width, wherein a rectangular lid and a rectangular bottom board are hinged together on one side so as to be closed, and when opened to an approximate ninety degree angle then reveal two separate playing fields each of congruent dimensions, with each playing field being a rectangular grid defined by a predetermined number of rows and columns which are sectioned into individual unit spaces, with each playing field having an equal number of rows, columns, and unit spaces, and where each unit space of each grid is of congruent dimensions;
• a first playing field, located inside a rectangular closable type playing board on a surface of a rectangular bottom board, that is used as an action area for attaching and removing a first set, a second set, and a third set of game pieces from individual unit space coordinates of a first playing field, wherein each individual unit space coordinate of a first playing field is rectangular in dimensions;
• a second playing field, located on a surface on top of a rectangular lid, that is used as a display area for attaching and removing a first set, a second set, a third set, a fourth set, and a fifth set of game pieces from individual unit space coordinates of a second playing field, wherein each individual unit space coordinate of a second playing field is rectangular in dimensions;
• a perimeter of space equal to one row of grid units surrounding both of the two playing fields such that one side above or below and one side to the left or right of each playing field grid are marked with alphanumeric symbols for the purpose of coordinate identification;
• five sets of game pieces in the form of rectangular tiles which measure a length and a height dimension that is less than or equal to a length and a height dimension of each individual unit space coordinate, wherein a first set of game pieces has a letter imprinted onto one side of a rectangular tile, and which is attached to and removed from individual unit space coordinates of a first and a second playing field grids;
• a second set of game pieces in the form of rectangular tiles which measure a length and a height dimension that is less than or equal to a length and a height dimension of each individual unit space coordinate, wherein a second set of game pieces has a shape imprinted on one side of a rectangular tile, and which is attached to and removed from individual unit space coordinates of a first and a second playing field grids;
• a third set of game pieces in the form of rectangular tiles which measure a length and a height dimension that is less than or equal to a length and a height dimension of each individual unit space coordinate, wherein a third set of game pieces has a number imprinted on one side of a rectangular tile, and which is attached to and removed from individual unit space coordinates of a first and a second playing field grids;
• a fourth set of game pieces in the form of rectangular tiles which measure a length and a height dimension that is less than or equal to a length and a height dimension of each individual unit space coordinate, wherein a fourth set of game pieces has a question mark imprinted on one side of a rectangular tile, and which is attached to and removed from individual unit space coordinates of a second playing field grid to indicate that a selected coordinate holds a first set, second set, or third set game piece that has been prepositioned by an opponent on a corresponding coordinate of a targeted first playing field grid and whose identity is unknown, and
• a fifth set of game pieces in the form of rectangular tiles which measure a length and a height dimension that is less than or equal to a length and a height dimension of each individual unit space coordinate, wherein a fifth set of game pieces has a red surface imprinted on one side of a rectangular tile, and which is attached to and removed from individual unit space coordinates of a second playing field grid to indicate that no first set, second set, or third set game piece has been prepositioned by an opponent on a corresponding coordinate of a targeted first playing field grid.
