GAME.

vApplication le'd April 24, 1920, SerialNo. 376,199. Renewed July 1'?,` 1924.

To all 'whomzt mag/concern.' i

Be it known that we, lViNrinLD R. Burnin and Gnonen C. FURINGTON, citizens of the United States, residing at 15 Brattle Street, Cambridge, county of Middlesex, Commonwealth of Massachusetts, and Fort Fairfield, county of Aroostook, State of Maine, re-

spectively, have invented certain new and useful Improvements in Games, of which the following is a specification.

This invention relates to games and particularly to a mathematical game involving computation in the moves in such a manner as to stimulate both the knowledge of and practice in certain branches of mathematics.

In games of an educational nature the necessity of sustained interest is very great as any lag in the sport of the play relegates 'the matter to one of task and the game -such games are carried on and one well adapted to impart rapid and accurate cal-y culation in both algebra and arithmetic.

In the drawings:

Fig. I is 'a game board and play pieces.

Figs. II, III, and IV are diagrammatic representations of fragments of a characteristic game in progress, and

Fig. V a representative score.

Fig. VI is a table of code values.

The apparatus comprises a tartan or plaided field A, preferably a square subdivided into 10() units a.. Opposite'sides of the field A constitute Borders or bases B in which are set down different values or factors opposite adjacent squares.

The pieces C are of disc or other suitable form and bear on their faces characters. These may be numerals or letters according as the play is to be of arithmetical or algebraio nature or may be both on opposite or combined faces.

The Scots or pieces C are two groups or clans each of characteristic color as for eX- ample Clan Bruce of characteristic red and Clan Elison-of blue, it being sufficient for `the purposes of this application to refer to the group of each player as reds `or blues. The pieces C each bear a value designation, letters or numbers, which constitute the factor of multiplication, addition, etc. of the computation ofthe play. j

Each group, ige. reds or blues is preferably subdivided asshown in Fig. I into two or more groups of the same value des-j. ignation and the designation of both are preferablysimilar so as to compel addition or multiplication. Forexample, if there are twosets of men on each side designated a and two b, there will be developed in ordinary play score points of a2 value or b2 value as well as those of ab value, etc. Also these values will frequently double or treble giving consolidated score items of 2a? or 362.

Referring to Fig. II it willbe seen that the Red Scot or piece having a value character a has jumped from its initial` position indicated in broken lines over the Blue Scot or piece having a value character b Y giving the resultant product ab.. This would be set'down in the red column. In Fig. III a red player value c has jumped a Blue Scot a giving a play product ac. In Fig. IV a red man value c has jumped a blue man of character c giving a play product -of c2. 1

`Along the border or base of each side adjacent check squares are assigned values which may be numbers or symbols.v In the drawings we have shown numbers which We prefer for present purposes.

In the use of the apparatus shown the Scots or play pieces C are lined up on the two rows of squares adjacent to each border.

As shown the pieces lettered a to e inclusive are arranged in that order in two rows. In play, however, the order may be varied `at will.y Each player assigns to the symbols of his pieces numericalvalues. These values may be announced or may be kept secret -fill the score is computed. Values may be either plus or minus. This stimulates the closest observation of an opponents play and a mental estimate of the mathematics of his strategy. The apparent careless exposingof a piece to attack may lead the enemy to guess its minus value and counter it with a minus piece thereby giving a plus value `to the product or score item of the move.

The` pieces are preferably moved diagonally along the diagonal lines of the overplaid E. Pieces are jumped or moved to the square or check next beyond that occupied by the enemy piece diagoiially next in front of it.

Any pieeereaching the border or goal line is rewarded by having its value character multiplied bythe value of the border square and the same added to the score.

The apparatus preferably includes a score space or board having separate columns divided by equation marks so that the productl of the jump items may be set down in a column and after cancellation or consolidation the nunierical values may be assigned and the score footed.

`While we have indicated as a preferred form pieces having alphabetical characters for algebraic play, it will be readily understood that multiplication or addition of numbers might be desired childrem All suchy modifications of characters, values, field or pieces are in accordance with our invention if within the limits of the appended claims.

lVhat we therefore claim and desire to secure by Letters Patent is:

l. ln a mathematical game apparatus7 aboard having va -eld of playsub-divided into a plurality of adjoining-units, the marginal units of opposite sides of saidfield having different values, and two sets of play pieces, the pieces of each set-having dillerent arbitrarily selected numerical values,

2. In a mathematical game apparatus, a board having a. rectangular iield of play symmetrically divided into uniform posi vith younger tion. squares, the marginal row of squares on each side. being of dilferent value characters, and two sets of play pieces, the pieces of each set having different arbitrarily selected numerical values.

l 3. In a mathematical game apparatus, a board having a rect-angular field of play symmetrically divided into uniform position squares, the marginal row of squares on nach side being of different mathematical factors, and two sets of playpieces, the pieces of each. set having different mathematical factors.

4f. A mathematical l game comprising an area of playand opposing play pieces of different arbitrarily selected numerical valuesl adapted to be moved in intersecting paths in said area ofiplay, and each having characters providing varying mathematical computations on the occasion of the intersecting meetings of opposing pieces.

5. A mathematical game comprising an area of play including positions of indicated values, and opposing play pieces of different arbitrarily selected numerical values adapted to be moved in intersecting paths in said area. of play and each having characters providing varying mathematical computations on the occasion of the intersecting meetings of opposing pieces.

In testimony whereof we alii-X our signatures in presence of two witnesses.
