ABSTRACT:
TECHNICAL FIELD
The proposed invention belongs to methods and technical implementations for performing lotteries and gambling with a random outcome.
BACKGROUND ART
There are known methods for proceeding of lotteries and games [
1
-
5
] in which the game situation with pseudo-random outcome such as in card games, roulette, lottery with winning numbers etc. is created with a gambling machine or computer. In those methods, a player makes a move, i.e. chooses an arbitrary combination of symbols (digits, numbers, characters, cards, roulette wheel zones, lottery card zones etc.) using the gambling machine controls and then the gambling machine picks the winning symbol combination to determine the result of the game. In the case of complete or partial coincidence of those two combinations the player gets an award. But the player can never be sure the game has really been accidental because the machine determines the winning symbol combination after the information of chosen by player combination became available. Thus, the machine may correct the move to its profit violating the random nature of the game. The game can be considered fair and random if only the player can make the move after the winning combination has been chosen by the machine and if the player can make certain the winning combination is unchangeable until the results are shown. It is noteworthy that in some games, like Black Jack, for the sake of the game fairness it's needed to determine and store in the machine unchanged not a winning symbol combination but a sequence of cards in the deck from which the players can pick out cards. Therefore, hereinafter we will refer to a symbol or combination of symbols picked out by the gambling machine for a general consideration.
There is a known method for performing games and lotteries [
6
] which is the closest to the proposed one in terms of aggregate of essential features. The method is taken as a prototype. In the method, a symbol or symbol combination is fixed in front of the observation window after revolving wheels with symbols plotted on their rims stopped. For the axed symbol or combination of symbols to be protected from seeing by a player the observation window is covered with opaque door until the player makes his own choice of symbols. Then the door is lifted up and the game result is shown.
However, the revolving wheels as the information carrier are hidden away from the observation and a player fails to assure himself the fixed symbol or combination of symbols (a position of the wheels) is still unchanged after the player makes his move and up to the result presentation. By this way the gambling machine may correct the winning symbol and lead the game on behalf of itself violating the random nature of the game.
There is a known gambling machine [
6
] chosen as the closest analogue (prototype), which contains: the unit for picking out a symbol or combination of symbols by the machine comprising the set of independently revolving fixable wheels with symbols plotted on the rims; the unit for picking out a symbol or combination of symbols by a player; the unit for a demonstration of the machine-picked symbol or combination of symbols to the player comprising an opaque removable screen mounted before of the machine-picked symbols with the possibility of their presentation after the player has made a move. Nevertheless, the wheels are hidden from the player and the player can't assure himself that after the moment the player makes his move and up to the moment of the result presentation the machine doesn't correct position of the wheels in dependence on the player's move and doesn't lead the game on behalf of itself violating the random nature of the game.
The objective of the proposed method and the machine for its realization is to protect a player from potentially unfair game. The attainable technical result enables a player to control an unalterability of that symbol or combination of symbols picked out by the machine until the moment of result presentation.
DISCLOSURE OF THE INVENTION
To achieve this technical result, in the method of gambling and/or lotteries performing, a symbol or combination of symbols is picked out by the gambling machine; a player is enabled to pick out an own symbol or combination of symbols; the symbol or combination of symbols picked out by the gambling machine is presented to the player; the symbol or combination of symbols picked out by the gambling machine is compared with the ones chosen by the player; as a result of such comparision the player's award is determined. Herein, there is enabled player's control of unalterability of the machine-picked symbol or combination of symbols until the moment of result presentation by the way of a player's visual observation of the state of an information carrier with the symbol or combination of symbols fixed on it by the gambling machine.
It's possible to realize the method by the way when fixation of a symbol or combination of symbols by a gambling machine is carried out by choosing an information carrier out of a set of those carriers; each of these information carriers at one side is marked by a symbol or combination of symbols. The control of unalterability of the machinepicked symbol or combination of symbols is carried out by placing symbol-free side of the chosen carrier within a player's field of vision. Presentation of the machine-picked symbol or combination of symbols may be accomplished by delivering of the information carrier to a player. Therein, it's possible to use the following kinds of information carriers:
information carrier in form of a card;
information carrier in form of a lotto element.
A machine-picked symbols or combination of symbols may be fixed by printing on the information carrier, herein, it's possible that:
information carrier in form of as a tape;
information carrier in form of a card;
two-layered information carrier with a dye-stuff between the layers.
The method can be realized by the way when a symbol or combination of symbols is picked by a gambling machine out of those plotted on a rim of at least one of revolving wheels which is stopped in the fixed position, for instance, in front of transparent window. The window can be set out parallel to the wheel's rotation axis and only one machine-picked symbol plotted on the rim, for example, can be seen through it. The control of impossibility for the symbol or combination of symbols to be changed is carried out by observation of invariable position of every wheel through another window placed, for instance, on the side of a wheel's butt-end.
Gambling machine for the method described to be realized is comprising: a unit for picking out a symbol or combination of symbols by the gambling machine; a unit for picking out a symbol or combination of symbols by a player, and a unit for presentation of the machine-picked symbol or combination of symbols to a player. Hereat, a unit for picking out a symbol or combination of symbols by the gambling machine is comprising means for a player to be assured in unalterability of the machine-picked symbol or combination of symbols fixed on, at least, one carrier until the result presentation. Wherein, a unit for picking out a symbol or combination of symbols by the gambling machine may comprise: means for a choice of, at least, one information carrier out of a set of those carriers at one side of which at least one symbol is plotted; and means for a feed of the information carrier by a symbol-free side within the player's field of vision. Hereat, a unit for presentation may comprise means for demonstration either only visually or with direct delivering of the symbol-holding carriers into player's hands. For realization of either the method or gambling machine various carriers can be used. In case of only visual presentation a carrier may be used repeatedly, a player does not receive it in his hands and the articles like chips, cards, cubicles, lotto elements or dominoe
