Arithmetic game

Claim 2

An arithmetic game comprising, in combination, a game board having thereon a playing field divided, by mutually perpendicular lines, into first rectangular spaces, aligned in mutually perpendicular first rows and first columns, for placing thereon first game pieces provided with digit symbols combinable with arithmetical operators and ''''equal'''' symbols to pose arithmetical equations; said playing field being further divided, by mutually perpendicular lines, into second rectangular spaces, aligned in mutually perpendicular second rows and second columns, for placing thereon second game pieces, some of which are provided with arithmetical operator symbols and others of which are provided with ''''equal'''' symbols; said first columns and rows alternating with said second columns and rows, respectively, whereby the four sides of each first space are bounded by two second rows and two second columns.

Claim 3

An arithmetic game, as claimed in claim 1, in which said arithmetical operator symbols and said ''''equal'''' symbols are imprinted in said second columns and second rows.

Claim 4

An arithmetic game, as claimed in claim 2, in which said arithmetical operator symbols are provided in alternate second columns and second rows, and said ''''equal'''' symbols are provided in second columns and second rows intermediate said alternate second columns and second rows.

Claim 5

An arithmetic game, as claimed in claim 1, in which said second spaces have a distinctive appearance distinguishing said second spaces from said first spaces.

Claim 6

An arithmetic game, as claimed in claim 4, in which said second spaces have dimensions differing from those of said first spaces.

Claim 7

An arithmetic game, as claimed in claim 4, in which said second spaces have a color differing from that of said first spaces.

Claim 8

An arithmetic game, as claimed in claim 1, in which each of said first game pieces is provided with a single digit symbol selected from the digits ''''0'''' through ''''9.''''

Claim 9

A game, as claimed in claim 1, wherein said game board is formed with recesses at each of said spaces, said recesses receiving said board pieces.

Claim 10

A game board, as claimed in claim 8, in which each of said recesses has a sloping bottom surface; said game pieces comprising blocks having correspondingly sloping bottom surfaces engageable with the bottom surfaces of said recesses.

Claim 11

A game, as claimed in claim 1, in which said pieces are blocks having a pair of opposite surfaces; said symbols being provided on only a single surface of a block.

Claim 12

A game comprising, in combination, a game board defining a playing field and constructed and arranged to receive board pieces at discrete spaced locations thereon; said game board carrying, between said locations, indicia imposing certain actions to be performed by the players; and a plurality of board pieces provided in multiples, for positioning at said discrete locations; said indicia representing arithmetical operators; at least some of said board pieces carrying indicia representing arithmetical elements useable with said operators; said game board being formed with recesses at each of said discrete spaced locations thereon, said recesses receiving said board pieces; and a two-part case releasably enclosing said game board and having a hand grip; the two parts of said case being substantially identical, and each part having, in longitudinal section, a substantially rectangular U-shape including a pair of elongated legs extending perpendicular to a base; said two parts being telescopable over said game board with said bases engaging opposite edges of said game board and the legs of each part overlapping legs of the other part; one leg of each part, adjacent its free edge, having projections from its inner surface engageable in openings adjacent the free edge of the overlapped leg of the other part; said projections extending through said openings into recesses in said game board.

Claim 13

A game comprising, in combination, a game board defining a playing field and constructed and arranged to receive board pieces at discrete spaced locations thereon; said game board carrying, between said locations, indicia imposing certain actions to be performed by the players; and a plurality of board pieces provided in multiples, for positioning at said discrete locations; said indicia representing arithmetical operators; at least some of said board pieces carrying indicia representing arithmetical elements useable with said operators; said game board being formed with recesses at each of said discrete spaced locations thereon, said recesses receiving said board pieces; and a two-part case releasably enclosing said game board and having a hand grip; the two parts of said case being substantially identical, and each part having, in longitudinal section, a substantially rectangular U-shape including a pair of elongated legs extending perpendicular to a base; said two parts being telescopable over said game board with said bases engaging opposite edges of said game board and the legs of each part overlapping legs of the other part; one leg of each part, adjacent its free edge, having projections from its inner surface engageable in openings adjacent the free edge of the overlapped leg of the other part; said projections extending through said openings into recesses in said game board.
