The track shown in Fig. 15 is composed of two circles touching each other, which are also connected with track sections along their external tangent lines. In the case shown in Fig. 16 the left side of the track is modified, so that it is connected laterally to a circular track section at the right side at the lateral touching points, as well as at the lower tangent point.

In Fig. 22 a threefold curved track inside a large external circle can be seen, which exhibits an image similar to the "Trinyang" symbol.

Fig. 23, Fig. 24 and Fig. 25. show various modes of embodiment of the track for the dexterity game according to the invention. As shown in Fig. 23, the track is produced as a V shaped track 2 in the game board 1, in which the ball 3 is located. As shown in Fig. 24, the track is produced as a rectangular shaped track 2 in the game board 1, in which the ball 3 is located. As shown in Fig. 25, the track is produced as an arch shaped track 2 in the game board 1 , in which the ball 3 is located. In case of the track configurations shown in Figs. 1, 2, 14, 18, 19, 20 and 21, the ball 3 moving in the track 2 is able to switch over from a given rotating direction to another determined rotating direction on the game board 1 without changing the general direction of the movement.

On the other hand, in case of the track configurations shown in Figs. 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 15 and 22, the ball 3 travelling in the track 2 can switch over from a direction of rotation to another determined direction of rotation, and then it can return to the original direction of rotation once again.

The preferred actual embodiments and applications of the game according to the invention are as follows:

The configuration is preferably circular, where arched transition is established within the circle along lines similar to the Yin- Yang symbol, with destination points and circular tracks in their continuation.

Base plate: made of plastic, wood or metal.

Possible forms of balls: small, large, made of plastic, wood, metal, other (stone).

Track: preferably wedge shaped, but it can have trapezoid, circle or square cross section also.

Our experiences indicate that the shape of the track 2 forming the track is important, the best is the V shape, so the V shaped track 2 is preferred, but the track can be also arched or rectangular. In given case we can use different size of balls too.

In case of a possible embodiment Fig. 15, 16, and 17 illustrates the simplest configuration of "ball track A B" and "ball track AB" corresponding to the principle of the present invention. This embodiment is less "attractive" relative to the more complex ones, but the principle of the invention is still valid here. The "ball track 1 and 2" is nice in its simplicity, and it allows the establishment of a small product, which fits into a palm. The principle of the invention is realised in case of "ball track 3" as well as in case of "ball track 2". Its further development is ball track 4 and 5 and the trinjang, which represent the possible embodiment of the various game versions. Its possible embodiment is preferably made from wood, and the ball tracks are not covered, where the balls might fall out if moved inadequately. It is possible to establish an embodiment of the game, where the track is provided with transparent cover surface, which prevents the balls from leaving the tracks. The material of the transparent cover and the game board constituting the track could be in the given case plastic, e.g. Plexiglas. In case of a possible embodiment of the game the board is not planar, but an arched shell surface.

The definition of this shape of embodiment is as follows, which at the same time corresponds to the explanation of the "ball track A B" and "ball track AB".

In case of a preferred embodiment of the invention, the subject of the invention ball tracks consisting of curved sections, characterised by that:

- it has at least one section (section "A") which has a single curve returning back to itself (preferably a circle),

- or it consists of curved sections, which together form a single continuous track that returns to itself, characterised by that the ball moving along the section "A" can travel from any points of section "A" with a continuous movement without stopping travelling in the same direction, so that it touches every point of section "A" a number of times.

- furthermore, it has at least one section (section "B"), characterised by that it has two end points, which are connected to section "A", and the end points of section "B" are characteristically are connected to section "A", so that the ball travelling along section "B" can approach section "A" from either end of section "B", and it passes to section "A while travelling into the same direction, and it keeps on travelling along section "A" corresponding to this direction, which direction is characteristically opposite to the direction from which the ball passed from section "A" to section "B".

In case of the game according to the invention the following details are the same and have the same roles as those of ball games known and used formerly:

- ball track,

- spiral shapes, which can be interpreted as consisting of nearly half circles,

- the ball is to be delivered from a starting point to a destination point,

- the table is stationary, and the ball is to be rolled manually (the board is to be tilted in case of Yin- Yang). Differences are as follows:

- the ball can travel continuously along at least two routes that return to themselves,

- the track has a part, which contains a section which returns to itself along at least two routes,

- each of these sections is curved, and ensures a continuous movement of the ball, which could travel through every point of the track section repeatedly, while the movement remains continuous,

- furthermore the branches between the track sections are curved, and allow that the ball changes to another track section while moving continuously,

- furthermore there are at least one branches, where each of the track sections, that can be selected when the ball is rolled, allows a returning movement,

- also, these track sections allows a change to opposite direction of rotation, where the direction of rotation remains the same at one of the track sections, and becomes opposite to the original direction of rotation at the other track section.

Application, use of the game according to the invention:

- The ball is rolled along the track established in a plane by tilting the planar board,

- for moving the ball along the track the planar plate supporting the track is continuously tilted in the direction where we want the ball to roll, and by carefully and harmonically moving the board the ball is caused to roll continuously,

- furthermore, the branches of the track are configured in a way, that the ball rolling along a circular path can be guided to the selected track section by an appropriate tilting of the board.

This principle can work in case of three internal circles without outside circle, only with three internal circles. The essential function is to change the direction of rotation without changing the principal direction of travel. The game according to the invention can also be used in manners other than holding in hands, placing on the planar surface, e.g. on a table, but we apply an arched e.g. spherical surface support, in the given case at the middle part of the board from below. This mode of manipulation give rise to a further possibility of tilting the game board on the supporting ball or arched surface to guide and roll the ball in the tracks in the game boards. This provides the dexterity game function as well as its expansion, where the user has to make tilting at the suitable direction at the appropriate time. This mode of application represents a significant difference relative to the„Spiral Billard" ball game, because the user moves the ball manually in this game, while the board supporting the track is manipulated in case of the solution realized by us. The mode of use also different from that of the Spiral Billard" ball game, because not the ball is guided itself, by the board is tilted when held in hand or by other manner.

The advantage of the game according to the invention includes the potential for developing skills and improving dexterity. It contain a ball track, the curve of which allows a continuous rolling, and this track depicts a Yin- Yang symbol in the given case. All curves consists of semi circles in case of a preferred embodiment, and the semi circles follow one another in a sequence, that the ball keeps or travelling in one direction of rotation, or start to travel in the opposite direction of rotation without stopping.

During the use, the ball changes direction of rotation while its movement remains uninterrupted. The changing of the direction of rotation takes place without changing the direction of movement. As a result of this, a game is realized when the rolling of the ball is "enjoyable" for the player, which can be produced with a harmonic movements.

The solution according to the invention allows establishing a game, in which a continuous movement is ensured by the curves. There is a construction, a structural design in case of the invention, which allows a certain kind of use, and at the same time, it allows the production of a game. In case of a preferred embodiment, it does not start from an inside point, but from an internal spiral curve. Yin- Yang is the simples shape with which it can be realized. The symbolism of Yin- Yang describes eternity with the harmonic interaction of dual pairs. The essence in philosophical substance the continuously movement of this game / tool, and it makes this feeling happen.

The configuration of the track may be established with three or more tacks in (arched) version. An additional difference relative to the solution of the Spiral Billard company, that the directions of rotation can be changed. This feature is not available with the previous solutions. The essential idea is to allow transition, changing the direction of rotation.
