FR2572298A1 - Device for monitoring the results of a game of chance - Google Patents

Abstract

The invention relates to a device consisting of a rectangular, rigid, thin, transparent plastic sheet, called a ''test card'' (''test pattern'') 1, on the reverse of which has been printed the rectangular outline of a grid of a game of chance of the Lotto (bingo) type 2. The device enables the player, after having circled the drawn numbers, to monitor his results by placing the test card (test pattern) over the grid or grids of validated slips, ensuring the superposition of the grid outlines: the winning numbers will be those whose crosses appear inside the circles.

Description

The present invention relates to a device for controlling the results of a game of chance, such as that of the Loto.

 The comparison between the numbers issued in the draw and those chosen by the player, which are materialized by crosses appearing on grids of numbers, is not without difficulties which could lead to errors of appreciation of the nature of the results, a fortiori in the case of subscriptions in which we have to compare several bulletins with the results of ten draws.

The device object of the invention eliminates these difficulties
It consists of a thin rigid rectangular transparent plastic sheet called "test pattern" on the back of which has been printed the outline of the grid, the dimensions of which are standard, ie approximately 19 × 50 millimeters.

 To check his results, the player applies the target to any grid, making sure that the respective grid contours coincide perfectly.

The grid on which the test chart is applied consists of an assembly of numbers from 1 to 49. it is therefore possible to write on the test chart using a fine-tip felt tip pen with special washable ink suitable for writing on plastic, the numbers released in the draw.

The 6 winning numbers will be surrounded by a circle the complementary number of a square0
The target thus overloaded is then confronted, in the same way, that is to say by superimposition, with the copies of the validated bulletins by making the contours of the grids coincide.

The winning numbers are those whose crosses appear in the center of the circles or the square of the target0
The test pattern is reusable indefinitely by erasing the ink inscriptions with a piece of moistened paper
In a first variant, the test pattern comprises on the back two screening halves of grid contours. This version allows you to check the validated bulletins for two weekly draws.

 In a second variant, the target has ten preprinted outlines of grid contours. This version makes it possible to control the validated bulletins for a subscription of five weeks, that is to say ten successive draws.

 The present invention leads to the manufacture and sale in large series of the device and to an increase in the felt-like outlets in washable ink, of which several models exist commercially.

 Figure 1 shows in (1) the plastic sheet or target on the back of which is printed the outline of a typical grid (2).

 FIG. 2 represents, by way of example, a test pattern overloaded with six numbers released at the draw, materialized by circles and a complementary number, materialized by a square.

FIG. 3 represents, by way of example, the target, overloaded with the same inscriptions as those appearing in FIG. 2, which was applied to a validated bulletin whose numbers chosen are those designated by crosses
The winning numbers are those whose crosses appear inside the circles.

 Figure 4 shows a test pattern for two prints.

 FIG. 5 represents a test pattern for ten draws, that is to say for a five-week subscription comprising two draws per week.

Claims (5)

Claims  1) Device for checking the results of a toto type game of chance, called a "test chart", characterized by, FIG. 1, a thin transparent rigid plastic sheet (1) on the back of which is printed the outline (2) d 'a Loto game grid.  2) Device according to claim 1 characterized by the fact, Figure 2, that the target can between overloaded with circles and square surrounding the numbers released in the draw, the ditsnumeros appearing by transparency on the underlying grid.  3) Device according to claim 2, characterized in that, Figure 3, the winning numbers are those whose crosses appear inside the circles or the square.  4) Disp ositif according to claims 1, 2 and 3, characterized by the fact, figure 4, that the test pattern comprises on the back two traces of pre-printed grids, thus allowing the control of validated bulletins for two draws.  5) Device according to claims 1, 2, 3 and 4, characterized by the fact, FIG. 5, that the target comprises on the back ten traces of pre-printed grids, thus allowing the control of the validated bulletins for ten draws,
