Casino gaming device with reverse pay table logic

Abstract

A computerized wagering game apparatus for wagering by a player has at least a game controller having a processor, memory, a random number generator and game logic generating winning and losing outcomes with assigned probabilities. For any single wager event, the probability for a winning wager outcome is greater than the probability for a losing wager outcome while maintaining a house retention on wagers by the game apparatus which is greater than 0% of all wagers. The house retention wager is effected by the apparatus decrementing a player account or machine credit without the player specifically placing that account or credit in play for the single wager event.

1 . A computerized wagering game apparatus for wagering by a player, comprising: a game controller having a processor, memory, a random number generator and game logic capable of generating at least one net winning or net losing outcome with assigned probabilities, 
 wherein for any single wager event the probability for a net winning game outcome is greater than the probability for a net losing game outcome while maintaining a house retention on wagers by the game apparatus which is greater than 0% of all wagers.    
   
   
       2 . The wagering game apparatus of  claim 1  with accounting logic capable of tracking the player's credit balance, 
 wherein for a single wager event the probability of a player's credit balance increasing as a result of the single wager is greater than the probability of a player's credit balance decreasing as a result of the wager.    
   
   
       3 . The wagering game apparatus of  claim 2  wherein the probability of a player's credit balance increasing as a result of the single wager is greater than 60 percent.  
   
   
       4 . A player-banked computerized wagering game apparatus for wagering by a player, comprising: a game controller having a processor, memory, a random number generator, game logic capable of generating game outcomes with assigned probabilities, and accounting logic capable of tracking the player's credit balance, wherein initiating play of a round of a game adds a wager amount to the player's credit balance and the game logic may assign at least one losing outcome to the player's credit balance after the completion of a round such that long term statistical house retention on wagers on the game apparatus is greater than 0% of all wagers.  
   
   
       5 . A method of playing a wagering game comprising: 
 a player initiating play of the wagering game by placing value at risk;    at least the player receiving randomly provided sets of symbols for use in the game;    evaluating a player's received randomly provided set of symbols according to at least one of predetermined rules of count, order, sets, matching symbols, rank of symbols, rank of combination of symbols, alignment of symbols, and numbers of triggering symbols;    assigning, tying outcomes with net tying effects, winning outcomes with net winning effects and losing outcomes with net losing effects based on received randomly provided sets of symbols;    wherein frequency of net winning outcomes for the player exceed frequency of net losing outcomes for the player and magnitude of winning effects and magnitude of losing effects under the rules for the game statistically assure house retention on wagers that is greater than 0% of all wagers.    
   
   
       6 . The method of  claim 5  wherein symbols are randomly provided by playing cards.  
   
   
       7 . The method of  claim 5  wherein symbols are randomly provided by spinning of a physical reel on a slot machine.  
   
   
       8 . The method of  claim 5  wherein symbols are randomly provided by a random number generator providing symbols on a display screen.  
   
   
       9 . The method of  claim 8  wherein a player places value at risk by placing a wager of a player-selected amount on a round of play of the wagering game.  
   
   
       10 . The method of  claim 8  wherein a player places value at risk by a processor allotting a player-selected amount of credit to the player's credit while placing at risk an amount of credit greater than the player-selected wager amount.  
   
   
       11 . The method of  claim 8  wherein summation of probabilities of net winning events multiplied by winning payback odds for each net winning event is less than summation of probabilities of net losing events multiplied by losing deduction odds for each net losing event.  
   
   
       12 . The method of  claim 8  wherein frequency of net winning events plus frequency of net tying events exceeds 60% of all wagering outcomes.  
   
   
       13 . The method of  claim 8  wherein frequency of net winning events exceeds 60% of all wagering outcomes.  
   
   
       14 . The method of  claim 8  wherein at least one net losing event has a magnitude of loss effect that exceeds at least the magnitude of 90% of all winning events.  
   
   
       15 . A computerized wagering game apparatus for wagering by a player, comprising: a game controller having a processor, memory, a random number generator and game logic capable of generating at least one net winning or net losing outcome with assigned probabilities, 
 wherein all possible net outcomes for the player comprise a probability distribution with an overall mean μ and an overall standard deviation σ,    wherein there exists a subset S of relatively small magnitude net outcomes consisting of those net outcomes that are greater than μ−√2σ and are less than μ+√2σ,    wherein there exists a subset L of relatively large magnitude net outcomes consisting of those net outcomes that are less than or equal to μ−√2σ or are greater than or equal to μ+√2σ,    wherein the mean of net outcomes calculated over subset S is greater than zero or the mean of net outcomes calculated over subset L is less than zero.
