preferred embodiments of the invention will now be described with reference to various examples of how the invention can best be made and used . like reference numerals are used throughout the description and several views of the drawing to indicate like or corresponding parts . referring now to fig1 and fig2 the golf course 10 according to a first embodiment of the present invention includes eleven holes extending over about 25 acres of land , as compared with about 60 acres or more of land required for a conventional nine - hole golf course . a round of eleven holes , numbered hole # 1 through hole # 11 , extends in a partially convoluted course pattern over a walking distance of from a minimum of about 1 , 000 yards to a maximum of about 1 , 265 yards commencing from a starting tee box 12 adjacent a clubhouse and parking area p and advancing sequentially from hole - to - hole along a circuitous round and terminating at hole # 11 near the starting tee box . a cup 14 and a set of tee boxes are located on each hole . each round includes nine ( 9 ) par three holes and two ( 2 ) par 2 holes , for a total of twenty - two holes suitable for regulation play . the holes are integrated into the existing rough environs 24 as shown in fig5 . preferably , the holes are spaced apart by a distance l that can be spanned in a single stroke , and the game is played in single strokes from hole - to - hole . because the course is partially convoluted , the last hole # 11 of the round is located near the starting hole # 1 , and play advances from hole - to - hole in clockwise fashion around the course . in the preferred embodiment , conventional fairways are not provided . the integrated rough areas are maintained only for aesthetics , and not for teeing or chipping purposes . optionally , the course 10 may include one or more ponds or lakes w . referring now to fig2 fig3 fig6 and fig7 using hole # 5 as an example , all holes have the following in common : a regulation cup 14 , or optionally an oversized 5 inch ( inside diameter ) cup , with a removable flag pole 16 ; a playing green area 18 in which the cup is embedded ; a grass cut fringe line that delineates the out - of - play ( op ) boundary line 22 of the hole ; and the rough area 24 between the out of play boundary line of one hole and the out of play boundary line of the next hole in sequence that forms a part of the existing natural rough . the distances between adjacent holes and the size of the op boundary lines are determined by the following rules : the spacing distances l between adjacent holes in sequence are measured from the center of the green of the previous hole to center of the green of the next hole in playing sequence . as used herein , “ hole - to - hole spacing distance ” is defined as the spacing distance l from the approximate center of the green playing area of a selected hole in the playing sequence to the approximate center of the green playing area of the immediately preceding hole in the playing sequence . the approximate center c of the playing green area 18 is located at a single stroke spacing distance l , for example 100 yards from the preceding playing green center , as shown in fig6 . for purposes of the present invention , the approximate center of the green playing area is defined as being coincident with the center or origin point c of an imaginary circle 26 that is substantially coincident with the green playing area . as used herein , “ hole - to - hole spacing distance ” refers to the straight line distance l between the approximate centers of any two adjacent greens within the playing round sequence . distances are rounded to the nearest yard . all par 2 holes are 65 yards ± 5 yards in length . two of the par 3 holes are 135 yards minimum , ± 5 yards and 150 yards maximum , ± 5 yards . two of the par 3 holes are 80 yards , ± 5 yards . two of the par 3 holes are 105 yards , ± 5 yards . three of the par 3 holes are 95 yards minimum , ± 5 yards , and 125 yards maximum , ± 5 yards . each green is separated from the rough by an out - of - play ( op ) boundary line . according to an important rule of the game of golf - 22 , a ball landing in the rough area outside of the op boundary line is out of play , and draws a penalty . in that situation , the player must move the ball from the rough and place it inside the op line on the green before resuming play . preferably , the boundary lines ( op lines ) between the green and the rough are established by differential height finger cut grass boundary fringe lines 22 as shown in fig3 and fig7 . the minimum and maximum range limits of the op boundary line are determined as follows : the distance f from the center c of the green to the out of play ( op ) boundary line 22 is the spacing distance l between the center of the green in play to the center of the preceding green multiplied by a predetermined scaling fraction k . preferably , for large greens , the scaling fraction k = k2 = 0 . 20 , and the limits are + 10 yards maximum , − 5 yards minimum . in this example , if the green in play is 100 yards from the preceding green , the op boundary line 22 would meander or vary from 15 to 30 yards relative to the center point c . that is , the op line winds and turns along a curved path that ranges or varies in its spacing distance not more than 30 yards and not less than 15 yards from the approximate center of the green playing area . the approximate center c of the green may be established or located by visual survey and inspection for each green . optionally , the center may be determined more precisely by the origin of an imaginary circle 26 that is substantially coincident with the green playing area , as shown in fig2 and fig6 . as used herein , “ substantially coincident ” means that all or nearly all of the area enclosed by the imaginary circle overlaps the green playing area . referring to fig2 all of the area enclosed by the small diameter circle 26 ( k 1 = 0 . 10 ) is coincident with the green playing area 18 . for the large diameter circle ( k 2 = 0 . 20 ), almost all of the enclosed area is coincident with the green playing area 18 . in either case , the nominal spacing of the op line from to the approximate center of the green playing area is proportional to a predetermined fraction k times the hole - to - hole spacing distance l . for a hole - to - hole spacing distance of 100 yards and scaling fraction k = 0 . 2 , the diameter of the imaginary circle 26 ( the nominal diameter of the op line ) is 20 yards . the green playing area boundary established by the op line varies or ranges within predetermined plus or minus limits relative to the imaginary circle and the approximate center c . by way of further example for a smaller green playing area , the distance g between the center c of the green playing area 18 and its op boundary line 20 varies in a range of about k 1 times the distance l between the center of the green on the present hole to the center of the green on the preceding hole , within the limits + 5 yards maximum , − 2 yards minimum . in this example , the scaling fraction k = k 1 = 0 . 10 . if the center of the preceding green is 100 yards from the center of the present green , the out - of - play boundary line would meander or range from a minimum of 8 yards to a maximum of 15 yards relative to the center c of the green playing area 18 . as a safety precaution , each op boundary line is spaced a minimum of 30 yards from any other op line and a minimum of 30 yards from an imaginary line l joining or bisecting the centers of any two greens . it will be understood that the size ( nominal diameter and range limits ) of the op line can be selected for each hole as desired by adjusting the scaling fraction k and ranging limits to accommodate safety spacing considerations as well as degree of playing difficulty . according to an important feature of the present invention , the playing green area surrounded by the out - of - play line for each hole is sized proportionally according to the hole - to - hole spacing distance , making the size of the green playing area for each hole commensurate with the single stroke driving distance to the hole . that is , the green playing area enclosed by the op line is relatively large for long distance holes and relatively small for short distance holes , as indicated by the large area op line 22 and the small area op line 20 in fig2 . the cup 14 is located anywhere on the green 18 at least 2 yards inside the op boundary line . in the exemplary embodiment of fig5 three tee box locations are provided for each hole : the red tee box r is located the shortest distance to the center of next green ; the white tee box w is located at the median distance to the center of the next green ; and the blue tee box b is located the longest distance to the center c of the next green . preferably , each tee box consists of a synthetic turf mat located within about 5 yards of the op line 22 , either fully inside the op line , extending partially across the op line or lying slightly outside the op line . the blue tee box may be placed to the rear of the cup outside of the op line for more advanced players , as shown in fig6 . in this arrangement , the green itself is used to make up the net single stroke driving distance from tee to next green . optionally , for intermediate and advanced play , at least two sand traps s and at least one mound m per hole may be provided , as shown in fig2 . a tee box inside or crossing the op line is treated as a mound . each sand trap s is located at least 1 yard from the op line . a sand trap may be combined with a tee box , but must be located as described above . in holes designed for beginning players , these features are omitted . the golf game of the present invention can be played on the golf course 10 in two ways : total points ; and , stroke play . for total point play , hole - in - one shots and green shots are counted only for the initial placement , and points are allocated as follows : for stroke play , par for 11 holes is 31 strokes , par for 22 holes is 62 strokes , and strokes are allocated as follows : if a tee shot lands out of play anywhere on the course ( e . g ., in the rough or in a hazard ), the player must take a penalty stroke , move the ball in a straight line toward the cup 14 from where the ball lies or was last seen . the player must take a drop anywhere on this line no more than one club length inside the op line 22 . referring now to fig4 a golf course 100 constructed according to an alternative embodiment of the invention is disclosed . this alternative embodiment is suitable for play out - of - doors or simulated on a computer , and is substantially identical to the course layout shown in fig1 except for the inclusion of three circular rings 102 , 104 and 106 that are concentrically disposed about the cup 14 . points are allocated according to the following rules : initial placement of the ball in the cup corresponding with a hole - in - one , 50 points . initial placement within the first ring 102 nearest to the cup , 35 points . initial placement within the second or middle ring 104 , 25 points . initial placement of the ball within the outermost ring 106 , 15 points . par , 0 points . each stroke under par , 10 points . each stroke over par , minus 10 points . in order to maintain a high level of game quality , a system of course rating is provided to allow development of a handicap system based on golfer performance over different courses . for example , a course rating system has been established on distance , with a higher rating point total signifying greater difficulty in play : rating hole nominal yards points par 2 65 0 par 3 @ 75 yards 75 0 par 3 @ 120 yards 120 0 par 3 @ 130 - 150 yards 130 2 135 4 140 6 145 8 150 10 par 3 @ 80 - 120 yards 80 2 90 4 100 6 110 8 120 10 although the invention has been described with reference to certain exemplary arrangements , it is to be understood that these examples are to be treated as preferred embodiments of the invention . various changes , substitutions and modifications can be realized without departing from the spirit and scope of the invention as defined by the appended claims .
a golf course is laid out for play in a front round and a back round , with each round being played on a sequence of eleven holes spaced apart along a course that traverses natural rough environs . the holes are integrated into the existing natural rough environs thereby forming playable green areas adjoining out - of - play rough areas . each hole includes a green located within an out - of - play boundary line , and the distance between the approximate center of the green and its out - of - play boundary line is fractionally proportional to the spacing distance that separates the green in play from the preceding green . all play is single stroke from green - to - green . the spacing distance from one green playing area to the next is limited to a predetermined distance that is calculated to allow it to be spanned in a single stroke by a beginning player . the green itself is used to make up the net driving distance thereby minimizing the total course acreage required for par play .
