before proceeding to a detailed description of the drawing , it is appropriate to note that in the illustrated example , the game board has been shown as one adapted especially to interest and amuse younger children . thus , in the illustrated example of the game board has a number of paths representing travel from a mud puddle to a garbage pit . the game pieces are in the simulation of small pigs , and the goal is to travel to the garbage pit from the mud puddle , so that the winning pig may wallow in and presumably partake of the garbage at the finish line . this is , of course , merely one embodiment of the game , and it is understandable that the game could utilize pieces in the form of spaceships , automobiles , etc ., respectively traveling to far - off galaxies , or in the case of automobiles , police cars , or taxis , through a labyrinthine maze of city streets . the various embodiments in which the game may be commercially produced are , it is believed , almost limitless . it is sufficient to note that in every instance , the game will have the structural and functional essentials illustrated and described herein , and no attempt will be made to discuss game rules or particular games that can be played , except to the extent absolutely necessary for the purpose of providing an understanding of how the game structure illustrated and described herein is constructed and used . in the illustrated embodiment , a game board 10 is formed as a laminate , rectangular , flat assembly of a base or circuit grid support plate 12 underlying and permanently secured in face - to - face contact with a cover plate or playing surface 14 . the circuit grid support plate 12 , in the illustrated embodiment , comprises a base plate member 16 formed of electrically insulative material , having on its upper surface a circuit grid generally designated 18 . the circuit grid can be a printed circuit , or alternatively , it could be formed of electrically conductive foil , ink , wires , or any other suitable means adapted to provide electrical paths within the grid . grid 18 basically comprises first and second sides of opposite polarity . the first side has been generally designated 20 , and as seen from fig8 in the illustrated embodiment includes an elongated , straight main circuit element 22 which in the illustrated example extends longitudinally of the game board along one side edge thereof . the main circuit element 22 is integral with a plurality of branch circuit elements 24 extending perpendicularly to the main element , transversely of the game board over a substantial portion of the width of the board . the branch elements 24 , in the illustrated example , are uniformly , closely spaced along the length of the main circuit element 22 , and can be of any desired number , there being 22 branch elements extending from the main circuit element 22 of side 20 , in the illustrated example . the opposite side of the circuit has been generally designated 26 . in the illustrated example , this includes a plurality of individual , separate main circuit elements 28 , 30 , 32 , 34 , 36 , 38 , and 39 respectively . again , the number may differ from game to game . indeed , the first side 20 of the circuit could itself comprise a plurality of individual main circuit elements , rather than a single main circuit element 22 . each of the main circuit elements 28 through 39 of what has been generally termed the opposite side 26 of the circuit has a plurality of individual branch elements alternating with and paralleling branch circuit elements 24 of the first side 20 . thus , circuit element 28 in the illustrated example has four , parallel branch elements 28a , 28b , 28c , 28d disposed in alternating , spaced parallel relation to branch circuit elements 24 of the first side 20 of the circuit incorporated in the game board . main circuit element 30 is provided with three branch circuit elements 30a , 30b , 30c alternating with other branch circuit elements 24 of the first side . main circuit element 32 has three branch circuit elements 32a , 32b , 32c ; main element 34 has branch elements 34a , 34b , 34c ; main element 36 has branch elements 36a , 36b , 36c ; main element 38 has branch elements 38a , 38b , 38c ; and main element 39 has branch elements 39a , 39b , and 39c . all the branch elements of the second side 26 of the circuit are in a ladder - like arrangement , in alternating , spaced relationship to the branch elements 24 of the first side 20 of the circuit . it is also important to note that the plurality of main circuit elements 28 through 39 of the second side 26 of the circuitry are normally free of any electrical connections to each other . rather , each of the main circuit elements 28 through 39 , at the end thereof remote from its branch elements , is formed with an electrical terminal 40 . the several terminals 40 , as seen from fig8 are arranged in an annular series , about a common terminal 42 centered in said series and formed upon the end of a common circuit connection 44 connected to an electrical lead 46 that is attached to one pole of a removable battery 48 , from the other pole of which extends a lead 50 connected to one terminal of a main power control switch 52 , the other terminal of which is connected to a lead 54 extending to one terminal of a flasher control device 56 connected at its other terminal by lead 58 to the main circuit element 22 of the first side 20 of the circuit . the battery , switch , and flasher control device 56 can all be enclosed in a housing 60 , which of course would be made readily removable so as to facilitate replacement or recharging of the battery . the connection of the individual circuit elements 28 through 39 of the second side 26 in circuit with the battery 48 is controlled by a circuit selector generally designated 62 and illustrated in fig4 and 7 as incorporating a diametrically extending , integral handle 64 which in the illustrated example , but obviously not necessarily , is in the simulation of an animal , in particular a pig , to increase its attractiveness to youthful players . the body 65 of the selector is of electrically insulative material , and has a flat underside overlying the several terminals 40 and the common terminal 42 . centrally provided in the body is a tubular sleeve 66 , constituting a spindle or stub shaft extending downwardly from the body into registering bearing openings formed in the plates 14 , 16 of the game board , so as to rotatably mount the selector 62 upon the playing surface as shown . in a preferred embodiment , the stub shaft or spindle 66 is so designed as to permit the selector to be bodily removed from the plates 14 , 16 , so that another selector can be substituted if desired . the purpose of facilitating ready substitution of one selector for another is to increase the versatility of the game , by having various types of electrical bridging elements 68 , any of which can be utilized . referring to fig5 and also to fig4 it will be seen that secured to the underside of the body 65 of the selector , is a diametrically extending bridging element 68 of electrically conductive material , having at its ends detents 70 engageable in electrically conductive pads 71 of the several terminals 40 . bridging element 68 is formed ( see fig5 ) with diametrically opposed , spirally extending , integral wiping contacts 67 , 67 which engage the center terminal 42 ( see fig4 ) to maintain the bridging element in electrical engagement with the center terminal in the various positions to which the selector is rotated . it will thus be seen that utilizing a selector such as shown in fig5 operation of the selector to a given position will connect two of the circuit elements of the second side 26 of the circuit , in circuit with the battery , so that they are &# 34 ; live &# 34 ;. all other circuit elements will be &# 34 ; dead &# 34 ; in the sense that no electrical current can flow therethrough , since they will not be connected to the battery . for example , if the selector is adjusted to a position in which the diametrically extending bridging element 68 engages the terminals 40 of circuit elements 28 and 36 , these circuit elements will be connected through the common terminal 42 and common circuit connection 44 , in circuit with the battery and hence will be &# 34 ; live &# 34 ;. referring to fig4 it may be noted that wiper arms extending downwardly from the central portion of the bridging element provide an electrical connection between the bridging element and the common terminal 42 so as to effect the connection of the selected elements 28 , 30 , 32 , 34 , 36 , 38 , or 39 to the battery . in another position of the selector , the elements 30 , 38 would be connected to the battery . in yet another position , elements 32 , 39 would be so connected . in still another position , the element 34 would be connected to the battery . it is possible , by substitution of one selector for another , to utilize selectors that have , for example , cruciform or t - shaped bridging elements . a cruciform bridging element would provide four bridging terminals , and would have the capability of connecting up to four of the elements 28 through 39 to the source of electrical power . a t - shaped element would connect three of said circuit elements to the source of power . it follows , of course , that the bridging element could simply be a radial arm extending from the center of the selector , so as to permit only one of the circuit elements of the side 26 to be connected to the source of electrical power . all of these modifications are believed sufficiently obvious as not to require special illustration herein . it is mainly important to note that the selector element , when rotated by the players during the course of a game , is continually changing those areas of the second side 26 that are &# 34 ; live &# 34 ; or &# 34 ; dead &# 34 ; electrically . this adds measurably to the interest in the game , since the players do not know which of said circuit areas are alive or dead at any given point during the course of the game . in the playing of the game , a plurality of game pieces 72 are employed . in the illustrated example these are in the simulation of piglets , and are of different colors , each game piece incorporating a molded body of electrically insulative material 74 , having in its top surface a recess in which is mounted a signal lamp 76 , connected by embedded leads 78 to exposed terminals provided upon the underside of the body in positions where they are adapted to contact a branch circuit element 24 of circuit side 20 , and a branch circuit element , as for example element 36c of the opposite side 26 of the circuit . it follows that with circuit element 24 being alive at all times , the signal lamp 76 will be energized when , and only when , the branch element of the opposite side 26 ( in the illustrated example the element 36c ) is energized according to the position of the selector 62 at that time . in the selector position shown in fig1 and 4 , the signal lamp 76 would be illuminated for the playing piece illustrated in fig2 because the selector has connected circuit element 36 in circuit with the battery , along with circuit element 28 , so that branch element 36c is live . accordingly , a circuit would be closed through the signal lamp 76 and the source of power , providing a visual indication that a successful move of the game piece along its assigned path has been achieved . this successful move is rewarded according to the particular game rules , and in the present example may result in the player being allowed to leave the game piece in the position to which it has been advanced . if advancement of the playing piece results in no energizing of the signal lamp 76 , the game rules may require that the piece be moved backwards , space by space , until the signal lamp again begins to blink by reason of its connection to the source of power through the flasher 56 . to protect the signal lamp there may be provided upon each of the playing piece bodies 74 , a dome - shaped , transparent shield 80 . the game pieces are movable along paths 82 formed as slots extending the full depth of the cover plate 14 . in the illustrated example , the slots are approximately parallel , and if desired they may curve somewhat as they extend from the start to the finish line denoted by the opposite ends of the respective slots . each slot , in the illustrated example , has opposed longitudinal edges formed with uniformly spaced , relatively shallow notches 84 representing steps along which the playing pieces 72 may be advanced . in the illustrated example , since the playing pieces are in the form of piglets , each playing piece has four legs 86 , adapted to be disposed in slots 84 whenever the playing piece is advanced . when the legs 86 of the playing piece are so disposed in opposing slots as illustrated in fig2 and 3 , the contacts defined by the lower ends of the leads 78 are in engagement with adjacent branch circuit elements of the respective sides 20 , 26 of the circuit . as previously noted , if the branch element of the side 26 happens to be energized at the particular time by reason of the selector position , the signal will be activated in the playing piece . thus , advancing the playing piece step by step assures that in every position to which the playing piece is so advanced , the contacts of its signal device will be in engagement with opposite sides of the circuit grid 18 . referring to fig6 a spinner is provided , and in the illustrated example , the spinner has been designated 88 and incorporates a rectangular , flat spinner base 90 on which is freely rotatable an indicator member 92 . this is in the general simulation of the usual arrow , so that when it comes to rest it will point to index markings 96 provided in colored segments 94 of the spinner . the rotary selector 62 has markings 98 , 100 , 102 bearing a relationship to the markings 94 , 96 of the spinner . for example , let it be assumed that the segments 94 of the spinner are of various colors such as yellow , blue , red or green . let it also be assumed that along each path 82 there are corresponding colored areas . if the game piece 72 is at the starting end of the path , shown at the left in fig1 and assuming that the spinner arrow has come to rest in the segment 94 that is colored green , the player whose turn it is advances his or her game piece to the first space of the path that is colored green . note , in this connection , that the markings 96 of the spinner , in a typical embodiment , alternate between black and white . thus , in fig6 the spinner arrow has come to rest in a segment which for purposes of explanation will be considered green , having in it a black dot or marking 96 . as previously noted , the player moves his playing piece to the next position in the path 82 that is colored green . the player now turns the selector 62 to the corresponding color combination , in this case black - green . referring to fig7 imprinted upon the game board , and extending about the selector , are opposed black and white boundary markings 98 , 100 respectively each of which is disposed in proximity to a series of colored , angularly spaced indicia 102 . let it be assumed , thus , that the spinner having indicated black - green as a combination , the player has advanced his piece to the next green area of his assigned path 82 , and has indexed the selector 62 to a position in which the head of the animal simulation 64 points to the green indicium 102 associated with and adjacent to black boundary marking 98 . in these circumstances , and keeping in mind that side 20 of the circuit is continuously connected to one side of the battery or other power source , the rotary selector will have connected to the other side of the battery the main circuit elements 28 and 36 of the second side 26 of the circuit . if it happens that the advanced piece is in contact with a live portion of side 26 of the circuit grid , the signal device 76 of that playing piece will be energized . in the present instance this is a lamp and it will blink by reason of the operation of the flasher . in a typical playing situation , this may permit the player to leave his playing piece at the location to which it has been advanced . if , on the other hand , the signal device is not energized , the rules may require that the player move the piece in a reverse direction , space by space , until the signal thereof eventually makes a circuit with a live portion of side 26 and is again energized . under the rules of the game , the player may under these circumstances halt the step by step reverse movement of his playing piece and leave it in the position to which it has been reversely moved until the players next turn arrives . obviously , the paths along which the playing pieces are moved do not have to be parallel , nor straight , and can follow various tortuous and even intersecting routes . it is necessary , only , that each path along which a playing piece is moved be crossed , at regular or even irregular intervals , by circuit elements of opposite polarity capable of being contacted by the terminals of the visual and / or audible signal device carried by the playing piece . and , as previously noted , so far as the circuitry is concerned , it is an important feature that at least one of the sides of the circuit comprise a multiplicity of circuit elements , not connected to each other , but capable of being brought either singly or in any combination thereof into circuit with the source of power , so as to have both live and dead circuit areas in at least one , and if desired in both , sides of the circuit . it is contemplated that in some instances , the game pieces may not have electrical means incorporated directly therein for the purpose of providing signals indicating a successful advance of the piece . for example , the playing pieces may be weighted , and the circuit grid may be sensitive to the weight of a playing piece in such a way as to close switches spaced along the paths 82 , whereby to actuate other electrical means located on the game board , including lights , buzzers , sirens , or the like . this arrangement , of course , would have in common with the illustrated arrangement the characteristic whereby the advancement of a playing piece to a &# 34 ; live &# 34 ; circuit area determined by the selector position , is effective to provide a visual and / or audible indication to the players resulting from a mechanical or electrical interaction between the playing piece and the underlying circuit grid . while particular embodiments of this invention have been shown in the drawings and described above , it will be apparent , that many changes may be made in the form , arrangement and positioning of the various elements of the combination . in consideration thereof it should be understood that preferred embodiments of this invention disclosed herein are intended to be illustrative only and not intended to limit the scope of the invention .
