Title: Gambling game system and method for providing variable odds

Description:
FIELD OF THE INVENTION 
     The present invention relates to a game system for providing variable odds and method thereof, and more particularly to a game system and method thereof for generating a numerical value of variable odds that is sufficient to attract players. 
     BACKGROUND OF THE INVENTION 
     For example, U.S. Pat. No. 9,646,459 discloses an incentive apparatus for gambling game systems, which is used to increase the odds of gambling game systems. The incentive apparatus for gambling game systems mainly uses a component for calculating variable odds of additional stakes, that randomly selects a fixed quantity from a plurality of game results and generates a variable odds of additional stakes for each of the game results, and then immediately displays the variable odds of additional stakes on an electronic display panel correspondingly, and for bets that have bet on the corresponding game results, a payout component pays the players based on a payout odds and by preferentially selecting the variable odds of additional stakes. Accordingly, the incentive apparatus for gambling game systems increase a rate of Return to Player (RTP), so that the players expect to obtain additional incentives from the gambling game system, and attractiveness of the gambling game system is enhanced, thereby increasing the utilization rate of the gambling game system. 
     However, the above method of enhancing the attractiveness of the gambling game system by increasing the rate of RTP directly sacrifices the operating profit of the game dealer. For the game dealer, although excessively a high rate of RTP can increase turnover, it is unfavorable to operating profit. When limiting the rate of RTP to meet the expected operating profit value of the game dealer, for the players, a maximum numerical value of the variable odds of additional stakes is still too small to produce an effect of attracting players.

     In addition, the at least one variable odds set meets the following conditions: the number of the variable odds  14  in all variable odds set are more than two; in one variable odds set, the numerical values of parts of the variable odds  14  are lower than the numerical values of the corresponding payout odds  13 ; and the numerical values of the others of the variable odds  14  are calculated according to a variable value of the rate of RTP which is made to meet a specified condition. The specified condition is selected according to actual needs. Preferably, the specified condition is that the variable value of the rate of RTP is a minimum. The variable value is a difference between numerical values of the rate of RTP before and after changing and then takes the absolute value. That is, the less a variation (including increase and decrease) of the rate of RTP the better. Ideally, in order to maintain the operating profit, the variable value of the rate of RTP being zero is the most ideal state. However, in actual calculations, there is a problem of being impossible to be divided with no remainder, so in practice, as long as keeping the variable value of the rate of RTP as minimum will be the most ideal state. In other embodiments, the specified condition is that the rate of RTP increases or decreases by a specified value to meet business requirements. 
     It should be noted that the rate of RTP of the game is obtained by first calculating the rate of RTP of each variable odds sets separately and then averaging all the rate of RTP thereof. Therefore, under the premise that the variable value of the rate of RTP is minimal, as long as the numerical value of part (at least one but not including all) of the variable odds  14  is lower than the numerical value of the corresponding payout odds  13 , numerical values of the others of variable odds  14  is effectively increased to attract the player to play the gambling game. In addition, the numerical values of the variable odds  14  provided in the embodiments of the present invention are only indicative values, but not actual numerical values of odds, which can be implemented by those skilled in the art based on the techniques disclosed in the present invention according to actual requirements. 
     After generating the at least one variable odds set, in each of the variable odds sets, the odds processing unit  30  selects one of the at least one variable odds  14  according to the probability to be selected to replace the corresponding payout odds  13  to allow the gambling game to generate an adjusted payout odds set. One embodiment of the adjusted payout odds set is shown in the table below.

     Finally, the game result generating unit  40  selects one of the game results according to the probability of occurrence in each of the rounds of the gambling game as a round result thereof. The payout unit  50  pays out according to the bet signal, the round result and the adjusted payout odds set. 
     In addition, in order to meet the demands of the player, the input unit  20  allows the player to selectively input at least one of the upper limit value, the lower limit value, or the amount of the at least one variable odds  14 , and then allows the odds processing unit  30  to generate the at least one variable odds set accordingly. For example, the player selectively inputs an upper limit value, a lower limit value, or amount of the variable odds  14  the can be accepted according to preference, and the odds processing unit  30  will generate the at least one variable odds set based on the player&#39;s input. Therefore, the player can obtain the different variable odds  14  in each of the rounds of the gambling game to maintain excitements. 
     In practice, the odds processing unit  30  generates the at least one variable odds set by a mathematical trial and error method. In detail, the odds processing unit  30  first randomly generates the variable odds  14  of the at least one variable odds set, including the amount, the numerical value, and the probability to be selected, under the premise of meeting the player&#39;s input conditions. Then the odds processing unit  30  calculates the rate of RTP to determine whether the variable value of the rate of RTP is positive or negative. When the variable value of the rate of RTP is positive (negative), it represents that the numerical value of the variable odds  14  is too high (too low), and the odds processing unit  30  will decrease (increase) the numerical value by adjusting with minimum unit and recalculate the rate of RTP until the variable value of the rate of RTP is changed to a negative number (positive number). After the variable value of the rate of RTP converges, the odds processing unit  30  selects a minimal absolute value of the variable value of the rate of RTP as the last variable odds set to meet the specified condition. 
     In addition, the game processing unit  60  further determines whether to allow the odds processing unit  30  to generate the at least one variable odds set according to a preset condition. In detail, the preset condition is set by the player or operator, or is used as a bonus in the gambling game, or only when a bet amount of the player exceeds a specified numerical value, the odds processing unit  30  generates the at least one variable odds set. Alternatively, an additional betting option  121  is provided in the betting area  12 , and only when the player bets on the additional betting option  121 , the odds processing unit  30  generates the at least one variable odds set. 
       FIG.  2    is a flowchart of steps of a method corresponding to a first embodiment. The steps of the method of the gambling game include: step S 1 : a betting step, step S 2 : a variable odds selecting step, step S 3 : an odds updating step, step S 4 : a game result generating step, and step S 5 : a payout step. 
     Step S 1 : the betting step, generating the bet signal by the input unit  20  through the player betting on the betting areas  12 . A step S 1 - 1  is alternatively performed thereafter. Step S 1 - 1 : determining whether to perform the variable odds selecting step. Namely, the game processing unit  60  determines whether to allow the odds processing unit  30  to generate the at least one variable odds sets, that is determining whether to perform the variable odds selecting step S 2 . If determining to select the variable odds  14 , continuing the variable odds selecting step S 2 ; and if determining not to select the variable odds  14 , proceeding directly to the game result generating step S 4 . 
     Step S 2 : the variable odds selecting step, generating at least one variable odds set by the odds processing unit  30 , and then selecting one of the at least one variable odds  14  according to a probability to be selected to replace the corresponding payout odds  13  to allow to generate the adjusted payout odds set for the gambling game. 
     Step S 3 : the odds updating step, displaying the adjusted payout odds set on the display unit  10  after completing the betting step S 1  and the variable odds selecting step S 2 , as shown in  FIG.  3 B . 
     Step S 4 : the game result generating step, generating the round result by the game result generating unit  40 . 
     Step S 5 : the payout step, paying out by the payout unit  50  according to the bet signal, the round result, and the adjusted payout odds set.
