The soccer playing field hitherto in common use is rectangle shaped and lined marked as part of the field, which it delimits it. The field is exteriorly delimited through two margin lines and two post lines and divided by the median line in two equal field halfs, the mid of the median line representing the centre of the playing field.

A gate is placed mid of each post line. The length of margin lines is, in any case, bigger than the length of the post lines, each of them having maximum and minimum limits for all playing fields types (broadly, for international games as well). Each extremity of the field halfs has, delimited by some lines, a post (gate) area, a penalty area and a penalty point, which is also the centre of the outer penalty area arc of circle. The margin lines intersect the post lines, according to 90° angles, in four points representing the corners of the field, marked by compulsory corner flags and corner arcs of circle. The extremities of the median line intersect the mid of the margin lines according to 90° angles in two points which can be marked with median line extremity flags.

The shape and dimensions (minimum and maximum ones) of all soccer playing fields (for international matches as well) according to Law lof the Matches Laws/1 1 are shown in the Fig. 1-5 of the works/3-6/and in Tables 1 and 2 (columns 4-7), and those of a handball playing field are illustrated in Fig, 1 of the work/7/.

Additionally to the Law 1-Playing field from the Playing Laws/1/, the following Fig. 1- 5 from the works/3-6/and Tables 1 and 2 contain the values of some new indicators : -St-the total surface of the playing field, m2, -Se-the ratio between the total surface St of the playing field and the teams number ne, m2/e -Sj-the ratio between the total surface St of the playing field and the players number nj, m2/j -Lc-the length of the playing field through its centre (the length of the playing field passing through the centre point and penalty points is equal with the length of the margin lines for the common playing field ; respectively the length of the playing field passing through the centre point and two penalty points, for the playing field according to the invention), m.

These new indicators have been used both in the manufacturing and obtaining processes of the playing field according to this invention and in comparison of the said field with the actual classic soccer playing field.

The soccer playing field hitherto in common use assures the practice of the actual soccer game between two teams, which takes place according to the Playing Laws established by FIFA and authorised by IFAB/1, 2/and which enjoys a large spreading and huge popularity around the world, being known as"the king of sports","universal sport".

The actual classic soccer game according to the Playing Laws/11 takes place between two teams, each formed of 11 players-one goalkeeper and 10 field players-usually distributed in three compartments with different tasks and attributes : the defence compartment, the midfield compartment and the attack compartment, the number of the players allocated to each compartment being determined by the playing system adopted by each team. The players role, the organization and the display of the actual classic soccer game are described in numerous works in the field/1, 2, 8-12/.

Despite all known and well-established qualities, which made it be known as"the king of sports", one can say the actual classic soccer have some real defects, such as : -the complexity, spectacular and creativity are limited and beneath the physical and tactical possibilities of the players and technical leaders, due to the fact the development of the soccer has reached a point hard to be surpassed and which can create a certain pattern, limitation and obstruction, which can only be resolved by using new solutions according to the present invention able to re-launch the soccer creative dimension by creating new technical-tactical and even strategic possibilities ; -the impossibility of checking and making a quick difference, through direct simultaneous confrontation of some winner teams value, in case of doubts regarding the achieved classification ; -the impossibility of reducing the tournaments duration, if required.

In view of these defects, the playing field for soccer and other sportive games, according to the present invention, is so devised that the playing field is more complex, allowing the progress of a soccer match and other sportive games, simultaneously, between three or four teams without any essential alterations of the soccer Playing Laws/1/ established by FIFA and authorised by IFAB or any other sportive playing Rules, above mentioned, except increasing the complexity and spectacular dimension of the said games.

The playing field according to the present invention for the simultaneous game between three, respectively four teams is identical with the actual classic playing field between two teams as far as the principal mentioned indicators are involved : -Se-the ratio between the total surface St of the playing field and the teams number ne, m2/e, -Sj-the ratio between the total surface St of the playing field and the players number nj, m2/j, -the dimensions and the mark of the : post lines, posts, post (gates) areas, penalty areas, penalty points, corner flags, median line extremity flags, corner arcs of circle, outer penalty fields arcs of circle, central circle, -the lines mark and the notation, the noting and mark area of the playing field.

The soccer playing field for simultaneous matches is polygonal shaped : -star polygon having three arms staggered one to each other with 120°, or -hexagonal polygon (hexagon), the three segments of the median line being staggered one to each other with 120° each of the said polygonal shaped playing fields being used depending on availability and according to the contest's rules.

The three armed star polygon shaped playing field eliminates the above mentioned defects due to its complexity which allows the simultaneous matches between three teams, being provided with a central point framed by the central circle, which forms the centre of the playing field from which this one divides itself in three equal parts (one for each team) through the three median line segments (equal and staggered one to another by 120° angles). The playing field is exteriorly delimited through three margin lines (each consisting of two halfs which intersects each other in 120° angles) alternated by three post lines. On each of these three post lines (identically to the actual classic playing field between two teams) a gate (post) is placed and the post area, the penalty area, the penalty point are marked. The intersections of the post lines with the margin lines (in 90° angles) are marked through six arcs of circle and compulsory flags. The intersections of the median line extremities with the margin lines half may be marked by three median line extremities flags (not compulsory).

The hexagonal polygon shaped playing field eliminates the above mentioned defects due to its complexity which allows the simultaneous match between three teams, being provided with a central point framed by the central circle, which forms the centre of the playing field from which this one divides itself in three equal parts (one for each team) through the three median line segments (equal and staggered one to another by 120° angles). The playing field is exteriorly delimited through three margin lines alternated by three post lines. On each of these three post lines (identically to the actual classic playing field between two teams) a gate (post) is placed and the post area, the penalty area, the penalty point are marked. The intersections of the post lines with the margin lines (in 120° angles) are marked through six arcs of circle and compulsory flags. The intersections of the median line extremities with the margin lines half may be marked by three median line extremities flags (not compulsory).

The soccer playing field for simultaneous matches between four teams is also polygonal shaped : -four armed cross polygon, the arms being staggered at 90°, or -octagonal polygon (octagon), with the four segments of the median line staggered at 90°, each of the said octagonal shaped playing fields being used depending on availability and according to the contest's rules.

The four armed cross polygon shaped playing field eliminates the above mentioned defects due to its complexity which allows the simultaneous match between four teams, being provided with a central point which is the centre of the playing field, framed by the central circle, from which this playing field divides itself in four equal parts (one for each team) through the four median line segments (equal and staggered one to another by 90° angles). The playing field is exteriorly delimited through four margin lines (each consisting of two halfs which intersects each other in 90° angles) alternated by four post lines. On each of these four post lines (identically to the actual classic playing field between two teams) a gate (post) is placed and the post area, the penalty area, the penalty point are marked. The intersections of the post lines with the margin lines (in 90° angles) are marked through eight arcs of circle and compulsory flags. The intersections of the median line extremities with the margin lines half may be marked by four median line extremities flags (not compulsory).

The octagonal polygon shaped playing field eliminates the above mentioned defects due to its complexity which allows the simultaneous match between four teams, being provided with a central point which is the centre of the playing field, framed by the central circle, from which this playing field divides itself in four equal parts (one for each team) through the four median line segments (equal and staggered one to another by 90° angles). The playing field is exteriorly delimited through four margin lines alternated by four post lines. On each of these four post lines (identically to the actual classic playing field between two teams) a gate (post) is placed and the post area, the penalty area, the penalty point are marked. The intersections of the post lines with the margin lines (in 135° angles) are marked through eight arcs of circle and compulsory flags. The intersections of the median line extremities with the margin lines half may be marked by four median line extremities flags (not compulsory).

The form and the dimensions of all soccer playing fields types for simultaneous matches between three, respectively four teams, according to the present invention, are shown in Fig. 6-25 of the works/3-6/and Tables 1 and 2 (columns 8-14), and the form and the dimensions of all soccer playing fields types for simultaneous matches between three, respectively four teams, according to the present invention, are illustrated in Fig. 2 H-5 H of the work m.

The processes of obtaining such playing fields for soccer and other sportive games, according to the present invention, consist of applying the following algorithm (rules) : a) Because of geometric reasons (and in spite of the classic traditional rectangular shaped soccer playing field for matches between two teams) the shape of the playing field designed for simultaneous matches between three teams will be either : -star polygon having three arms staggered one to each other with 120°, or -hexagonal polygon (hexagon), with the three segments of the median line staggered at 120°, each of the said polygonal shaped playing fields being used depending on availability and according to the contest's rules. b) Because of the same geometric reasons (and in spite of the classic traditional rectangular shaped soccer playing field for matches between two teams) the shape of the playing field designed for simultaneous matches between three teams will be either : -four armed cross polygon, the arms being staggered at 90°, or -octagonal polygon (octagon), with the four segments of the median line staggered at 90°, each of the said polygonal shaped playing fields being used depending on availability and according to the contest's rules. c) For the actual classic soccer and other sportive games playing field the values of the indicators, which are calculated, are : -St-the total surface of the playing field, (St= Length x Width), m2 -Se-the ratio between the total surface of the playing field and the team number, (Se=St/ne), m2/e -Si-the ration between the total surface of the playing field and the players' number, (Sj= St/nj), m2/j. d) For the simultaneous matches of three or four teams soccer and other sportive games playing field the values of the St indicator (the total surface of the playing field, m2) are calculated by multiplying the teams number with the value of the Se indicator (calculated for the actual classic soccer and other sportive games playing field) (St= nexSe). e) In order to maintain the identical geometric conditions for both two soccer team matches and three, respectively four soccer teams matches, the values of the following indicators and parameters are maintained identical : -Se-the ratio between the total surface of the playing field and the team number, m2/e' -Sj-the ration between the total surface of the playing field and the players' number, m2/j, -the length of the post lines, m, -the mark and the dimensions of the post lines, posts, post area, penalty point, penalty area, arc of circle from the penalty point, compulsory corner flags, corner arcs of circle, mark of the post lines (not compulsory)' -the mark and the notations of the margin lines, post lines, median line, centre of the field, central circle, posts areas, penalty areas, penalty point arcs of circle, compulsory corner flags, median line extremity flags (not compulsory), corner arcs of circle, post lines marks (not compulsory).
