The invention is a logic game consisting of. a transparent or semi-transparent stationary base¬ plate divided into various colour fields, and fur¬ thermore of coloured mobile bodies, preferentially square plates made of transparent or semi-transpa¬ rent sheet and of a cover. The square plates are located on one or both sides of the stationary baseplate In a way that - except for one square plate - they cover the stationary baseplate. When a square plate is moved to cover the missing square, the "hole" migrates and so the sequence of square

plates can be altered. The size of coloured fields on the stationary baseplate is similar to that of the square plates and the coloured fields and the square plates below and/or above them are in co- vorugo, except whαn a oqunre plate io being ohi Fl¬ ed from one place to the other. The fields and the square plates are advantageously coloured to one of the three basic colours (e.g. yellow, blue and red) or to the blend of any two of these colours, the material being advisably glass or transparent plastic. The cover surrounds the stationary base¬ plate and the square plates, with the size of open-inn--- on it being smaller than that of the square plates. The number and place of apertures are identical with those of the fields on the sta¬ tionary baseplate. V/hen the game is held in the way of light or against a lit object, the various transparent material layers can be viewed through the opening of the cover and if the square plates are not in the process of shifting but pushed to their places, each cover opening is associated with a colour, which could be a basic colour or different blends of the basic colour, depending on the "stacked" layers and their number, respective¬ ly. The task could be to reach a situation by

shifting the square plates, whereby the same colour blend (e.g. brown) is seen through all cover open¬ ings.

There are many logic games (toys) where the task is to arrange oβvβral elements of different colours •into a certain colour sequence. Such a game is for example Rubik's cube (17o o62 _> R _U bi Erne,Hungary/, where each side of a cube is divided into nine squares and after arrangements by rotation the purpose is to make all squares on one side unico- lour. In the case of the game known as Babel tower, the coloured elements are balls which are to be grouped by rotation according to colours, making a sequence of the unicolour balls so that the co¬ lour proceeds from light to dark. It is a common feature of such games (toys) that since the co¬ loured elements are non-transparent, they must be grouped side by side, consequently a large number of elements is necessary to make the task appro¬ priately complex. Babel tower has more than thirty coloured elements, and Rubik's cube has 54. As a result, a disadvantage is the complicated structure. In addition, there are also toys with shiftable squares, the movement principle of which hns been used in this invention.

The concept we have started out from when develop¬ ing this game was that if we used transparent co¬ loured elements in the game, they can be put one behind the other, ensuring that one covers the other, and when they are illuminated, the colours are blended, thereby establishing a new mixture of colours, which will, however, still function as a single coloured element. In this way the number of functions on a given area is higher, and a rich variation of possibilities can be achieved in a small place with some coloured elements. What is more, the human eye can only see the final colour blend through each cover opening, and it is unable to distinguish each separate transparent layer "stacked", consequently the player may only draw conclusions about the colour of each layer by lo¬ gic. Therefore, solving tho problem of such cover¬ ing .layers, for example arranging to one colour is a very complicated challenge requiring much think¬ ing.

Our invention is demonstrated by way of Fig. 1. This figure depicts a three coloured layer design, in a way that the layers and the two- halves of the cover have been moved away from each other in a vertical direction ("exploded diagram").

The colourmix logic game embodied by the inven¬ tion consists of transparent or semi-transparent stationary baseplate (4) divided into fields (5) of various colours, as well as of coloured bodies designed of transparent or semi-transparent plates, preferentially of square plates (3) and of cover (1). The square plates (3) are located on one or both sides of stationary baseplate 4 in a way that - except for one square plate (3) - they co¬ ver stationary baseplate 4. The size of coloured fields arranged on the stationary baseplate is si¬ milar to that of the square plates and the coloured fields as well as the square plates below and/or above are in coverage, except when a square plate is in the process of being shifted. The cover sur¬ rounds the stationary baseplate and the square plates, and the openings on the cover ore smaller than _, the size of square plates. The number and place of apertures are identical with those of the fields on the fixed baseplate. Fig. 1 depicts a configura ion where stationary baseplate (4) is divided into six square-shaped fields (5) of preferentially identical areas, and coloured to a basic colour, that is to the blend of two basic colours (yellow, blue, red and orange,

respectively). Be-low and above the stationary base¬ plate (4) there are five each of transparent or semi-transparent square plates (3), the size of which is preferentially identical with that of fields (5). Square plates 3 may be edged or rounded. At the top and at the bottom is cover (1) which is preferen ially made of non-transparent material and which surrounds, "houses" stationary baseplate (4) and square plates (3). There are openings (2) on cover; (1) and they have for example a round shape.

The game consists of shifting square plates (3) to the currently available empty space, in the cc. e of square plates (3) located both belov. and above stationary baseplate 4. The shifting of square plates 3 is advisably carried out with the finger¬ tip through apertures 2 of cover 1. Fig. '1 shows a colour arrangement when through all the six openings (2) of cover (1) the same co¬ lour blend, i.e. brown is seen, in other words when the task is solved. In this case, at all six positions the three basic colours (yellow, blue., and red) are blended and at the position where a square plate (3) is not located and so there are only two layers above each other, orange (the mix-

ture of red and yellow/ is blended with blue. Symbols: 6 yellow, 7 blue, 8 red, ? orange.

Table 1 shows how many colours can be created by shifting square plates /5/ in addition to square plates /3/ and the fixed baseplate fields of the colours shown in Fig.l.
