Gaming device and method offering primary and secondary games

A gaming device and method for offering a primary and secondary game is set forth. The primary game may be a video poker game. When the player obtains a predetermined outcome in the primary game such as a flush, the player receives a reward and the secondary game is initiated wherein the player is presented with a field of game choice symbols representing hidden values. The player selects symbols which reveal the selected hidden values. If the revealed hidden values correspond to a secondary winning outcome, the player receives an additional reward.

FIELD OF THE INVENTION 
The present invention relates to electronic and electromechanical gaming 
devices and methods. More particularly, it relates to games presenting 
both a primary and secondary game. 
BACKGROUND OF THE INVENTION 
The gaming industry is perhaps one of the most fertile areas for game 
innovation in an attempt to continue to stimulate players to encourage 
them to play. While creativity is quite high, the attrition rate for games 
can also be high if the game is not accepted by consumers. It has also 
been found that by providing a game which offers large jackpots, play can 
also be stimulated. 
One strategy in maintaining consumer interest is to stimulate play by 
offering large, progressively accumulated awards. Progressive type 
machines are example of such two tiered systems where the players are 
encouraged to achieve an extraordinary payout while playing a primary 
game. It has been observed that after the extraordinary payout occurs, 
participation in the underlying game decreases abruptly. 
Marnell II, U.S. Pat. No. 5,393,057 shows use of a video poker game or 
reel-type slot machine for the primary game and a bingo type game as a 
secondary game. Certain outcomes from the primary game are reflected in 
the second game bingo card and, upon the occurrence of obtaining outcomes 
from the first game which are reflected in the second game in a 
predetermined pattern resulting in a bingo, a secondary award is made to 
one or more players responsible for obtaining the bingo. 
Another game presently used includes a primary game, such as a presentation 
of a multiple reel-type slot machine. A player makes a wager to play the 
primary game. If the player obtains one or more designated symbols on the 
pay line for the machine, a secondary reel is activated which selects the 
award to the player. In these games, the outcomes of the primary and 
second games are, basically, randomly selected. The player is offered no 
semblance of an opportunity to effect the outcome of the second game. 
In another game which has heretofore been provided, an electronic game is 
provided wherein the primary game is video poker. The player makes a wager 
and initiates play of the primary game whereupon representations of five 
playing cards are displayed at the game display. The player can select 
none, one or all of the cards to save. Once the selection has been made, 
the player draws whereupon the processor for the device replaces any 
discarded cards with replacement cards to define an outcome for the 
primary game. The outcome obtained in the primary game is sensed and 
compared to stored data representing winning primary game outcomes. If no 
winning outcome is sensed, the player's wager is lost and retained by the 
machine. If the outcome matches one of the primary game winning outcomes, 
the player is rewarded according to an established pay table. When a 
winning outcome is obtained, the machine offers the player an opportunity 
to double their reward by optionally participating in a secondary game. If 
the player opts to participate, the processor selects from a data registry 
containing data representing each card of a deck of 52 cards, data 
representing five cards. The selected cards are displayed as one card face 
up, denoted as the dealer's card, and four cards face down. The player 
must select one of the face down cards, the player's card, which he 
believes when revealed will outrank the dealer's card. By using selection 
buttons the player makes the selection whereupon the processor is prompted 
to reveal the value of the selected card and compares it to the dealer's 
card. If the player's card outranks the dealer's card, the player's 
initial reward is doubled. If it is a tie ranking, there is no action and 
the primary game reward is neither lost nor doubled. If the player's card 
is of a lesser ranking, the primary game reward is forfeited. 
The above games suffer from several drawbacks. One is that these games 
cannot offer, for the secondary game, large jackpots. Further, there is no 
feature of giving the player selection opportunities in the second game. 
Thus, the player cannot feel that they can control their destiny by making 
correct or "lucky" selections. Further, in many of these games the player 
must risk the reward from the primary game to participate. If they lose 
the secondary game, they lose their reward obtained from the primary game. 
What is needed is a device and method which provides for play of a primary 
game during which the player has presented, from time to time, a secondary 
game offering the player the chance to obtain a high, secondary reward, 
offering the player further opportunities of choice and which does not 
risk any reward obtained during the play of the primary game. 
SUMMARY OF THE INVENTION 
There is, therefore, set forth according to the present invention a method 
and device for playing a game offering a primary and secondary game. The 
method includes providing a primary game played by a player to obtain 
primary game outcomes. The first game may be a video poker game, a 
multiple reel slot machine, keno or the like. The method further includes 
the player making a wager to play the primary game to obtain an outcome. A 
triggering event is selected which occurs during play of the primary game. 
This triggering event may be one or more pre-determined outcomes obtained 
from the primary game, based upon the wagering history at the machine, 
based upon time or combination of the foregoing. Upon occurrence of the 
triggering event, e.g. the player obtaining a flush playing a primary game 
of video poker, a secondary game is provided offering a field of game 
choice symbols representing hidden values. In the preferred embodiment as 
hereinafter described, a matrix of symbols is presented, each representing 
hidden values which are the faces of playing cards. The player to play the 
secondary game selects a plurality of symbols from the field of game 
choices, the selection revealing the hidden values which define the 
secondary game outcome. The secondary game outcome is compared to 
pre-determined secondary game winning outcomes to determine if the player 
is entitled to an additional reward. If the player is indeed entitled to 
an additional reward, the reward from the secondary game is added to any 
reward obtained by the player for the primary game. Thereafter, the method 
includes returning to the player playing the primary game. 
The device according to the present invention includes a display and data 
processor including a data structure storing data corresponding to at 
least one triggering event. As stated above, the triggering event may be 
an outcome obtained during play of a primary game, based upon the wagering 
history at the machine, time or the like. Means are provided at the device 
to receive a wager to play the primary game. Means are provided for 
sensing play of the primary game and for generating data signals in 
response thereto. For example, these means may sense outcomes. The 
processor for the device includes means to compare the data signals to 
data corresponding to the triggering event to determine if the triggering 
event has occurred. If the triggering event has occurred, such as where 
the player is playing a primary game of video poker and has obtained the 
pre-determined triggering event of a primary game outcome of a flush, the 
processor is adapted to issue signals to the display to display a 
plurality of secondary game choice symbols, the symbols representing 
hidden values. Means are provided for the player to select a plurality of 
symbols, the processor in response to the selection of symbols adapted to 
reveal at the display hidden values defining the secondary game outcome. 
The secondary game outcome is compared to data corresponding to at least 
one winning secondary game outcome represented by data stored in the 
processor data structure to determine if the secondary game is a winning 
outcome. Means are provided for rewarding the player if he has obtained a 
secondary game winning outcome whereupon the processor returns the player 
to the primary game. 
As can be appreciated, the method and device according to the present 
invention does not require the player to risk any reward they may have 
obtained during play of the primary game, offers the player choice options 
in playing the secondary game and is presented in such the manner that 
large rewards can be provided.

DESCRIPTION 
Turning to the drawings, FIG. 1 shows a gaming device 10 according to the 
present invention and adapted to practice the method of the present 
invention. While the device 10 as illustrated in FIG. 1 and the 
description as hereinafter provided is directed to the device 10 offering 
a primary game of electronic video poker, it is to be understood that the 
device and method could be employed with other primary games such as video 
keno, electromechanical, multiple reel, slot machines, electronic slot 
machines and the like which are well known in the art. Further, while the 
primary game as hereinafter described is directed to a stud poker video 
game, it is to be understood that the device and method of the present 
invention could be employed with other types of video poker games such as 
deuces wild and Jokers/deuces wild. Still further, the device 10 and 
method according to the present invention could be used with other video 
games such as video Caribbean Stud.TM., video Let It Ride.TM.. These 
primary games are well known in the art. 
The device 10 has a housing 12 of conventional design. The housing 12 
mounts, as shown in FIGS. 1 and 2, a video display 14 also of conventional 
construction. Where the device 10 is an electromechanical multiple reel 
slot machine, the display 14 would provide a view of the rotating reels of 
the slot machine in a known manner. Disposed within the housing 12 is a 
processor (not shown) likewise of known design. The processor, as is well 
known with conventional electronic gaming devices, controls the operation 
of the device and presentation at the display 14. 
Preferably the video display 14 has provided therewith a touch screen 
device 16 of known construction whereby the player, by touching a location 
on the device 16 which overlays the display 14 can input data to the 
processor. 
To receive wagers, the device 10 includes a coin slot 18 through which 
coins or token are inserted into the device 10 to play the game. In a 
known fashion, when a coin or token is inserted into the coin slot 18 the 
authenticity of the coin is tested, the coin is received and dropped into 
a hopper or other collection container and the coin receiving mechanism 
issues a data signal to the processor indicating receipt of the wager. 
Alternatively, the device 10 may have associated therewith a cash 
receiving device (not shown) of known construction whereby a player can 
insert paper currency which is read and authenticated and which, in 
response to authentication transmits a data signal to the processor in 
response thereto. For example, if the device 10 is a 25.cent. machine, a 
player by inserting a $20 dollar bill into the cash reader would result in 
issuance of a data signal to the processor to register 80 credits 
available for wagering at the device 10. As shown in FIG. 1, the credits 
available for wagering and accumulated during play of the game or upon 
inputting wagers or cash denominations are shown at credit location 20. 
Continuing with FIG. 1, the device 10 has a coin tray 22 to receive coins 
or tokens dispensed by the device 10 to the player. Also the device 10 has 
a candle 24 which provides lights for the machine by which the player may 
signal an attendant in to which is lit by the processor in the event of a 
malfunction, jackpot or the like. 
In a known configuration, the device 10 further includes a plurality of 
operation buttons 26a-j. By these buttons the player may control the play 
of the game, wagers, and the like. With continuing reference to FIG. 1, 
button 26a if depressed, lights candle 24 to signal the attendant that, 
for example, the player needs change or that the machine has 
malfunctioned. Button 26b represents a cashout button which, if depressed 
by the player, causes the device 10 to dispense all winnings accumulated 
as credits into the coin tray 24. Button 26c, if depressed by the player, 
controls the processor to wager, each time button 26c is depressed, one 
credit. Buttons 26b-h are used, in a manner described below, to control 
the play of the primary game shown, in FIG. 1, as video poker. The 
aforesaid buttons 26d-h enable the player to hold and discard cards in a 
well known fashion. Button 26i enables the player, upon depressing button 
26i, to wager the maximum amount of credits permitted at the device 10. 
Presently, most devices 10 of the type illustrated in FIG. 1 enable the 
player to make a maximum wager of five credits. Accordingly, by depressing 
button 26i, the processor would be controlled to deduct five credits from 
the accumulated credits shown at credit location 20 and to initiate play 
of the primary game. Finally, button 26j is a deal/draw button. If less 
than the maximum amount permitted at the device is wagered, the player 
depresses the deal/draw button 26j to initiate play of the game. 
Furthermore, deal/draw button 26j is also depressed to, after the player 
has discarded or held the cards desired, complete the play of the hand and 
obtain an outcome for the primary game. 
With the foregoing described, play of a primary game of video poker 
available according to one embodiment of the present invention will now be 
described. 
The player first makes a wager for the primary game. This is done by 
inserting coins or tokens at coin slot 18 or by wagering accumulated 
credits by depressing single wager button 26c or maximum wager button 26i. 
In the preferred embodiment of the present invention, for a player to be 
entitled to participate in the secondary game hereinafter described, the 
player must make a maximum wager. Assuming that the player has made the 
maximum wager by depressing button 26i, the processor initiates play of 
the game by randomly selecting from data stored in a suitable data 
structure data representing five playing cards. The processor drives the 
display 14 to display representations of the five playing cards 
representing an initial holding for a poker hand. From this initial 
holding as displayed at display 14, the player must decide which of the 
cards to hold and which to discard. The player makes the selection by 
depressing the button 26d-h corresponding with the cards to be held. As 
shown in FIG. 1, from the initial holding, the player depressed buttons 
26d, 26e and 26h to hold the five of diamonds, two of diamonds and three 
of diamonds. After the player has made the selection of the cards to be 
held, he/she depress the deal/draw button 26j which replaces the discarded 
cards with replacement cards as randomly selected from the data structure. 
As shown in FIG. 1, the replacement cards are the Ace of diamonds and four 
of diamonds. Once the replacement cards have been displayed, the final 
hand is shown and represents the outcome of the primary game of video 
poker. When the primary game outcome has been obtained, the processor 
compares the data corresponding the poker hand outcome with data stored in 
a data structure to determine if the primary game outcome corresponds to a 
pre-determined primary game winning outcome. If the primary game outcome, 
shown here as a straight flush in diamonds, is a winning outcome, the 
player receives a reward based upon a predetermined pay table 30 which may 
be displayed at display 14. Below in Table 1 are some exemplary primary 
game winning outcomes and payoffs for stud, video poker.

______________________________________ 
It is to be understood that other pay tables could be adopted for payoffs. 
Further, for different games such as deuces wild and Joker's wild, 
different pay tables are established. 
If the primary game outcome corresponds to a pay table winning outcome, the 
player is rewarded according to the pay table 30. If the outcome does not 
correspond to a pay table winning outcome, the wager is lost. Once the 
outcome has been resolved, the player re-initiates play of the primary 
game, here video poker, to obtain additional outcomes. 
As is well known, many players simply play a primary game of video poker, 
or the derivations thereof, for fun and excitement. Their only chance of 
obtaining a reward is to obtain a corresponding, winning outcome. For the 
greatest payoff, the player must obtain a royal flush. Some establishments 
have offered greater payoffs if the royal flush is in sequence, e.g. A K Q 
J 10. 
Furthermore, as discussed above, the primary game may be one of either 
electronic or electromechanical slot machines, electronic keno or other 
games provided in either electronic or electromechanical format. Suffice 
it to say, during the play of each of these primary games, the player 
makes a wager, initiates play and obtains a primary game outcome, which 
may be a winning outcome or a losing outcome. 
To increase the excitement of play, the device 10 and method according to 
the present invention provides a secondary game. According to the method 
of the present invention, the player playing the secondary game does not 
risk any rewards that he/she may have received in the primary game, gives 
the player choices and can offer large rewards. 
To participate in the secondary game, one or more triggering events are 
selected which, if sensed during play of the primary game, initiate play 
of the secondary game. With reference to FIGS. 1 and 4, the selected 
triggering events 32 may be the player obtaining one or more predetermined 
outcomes of the primary game or may be as at 32' based upon the historical 
wagering record of wagers made at the device 10. With reference to FIG. 1 
and FIG. 4, it is seen that the player during play of the primary game has 
obtained a straight flush in diamonds. According to the preferred 
embodiment, the triggering event is the player obtaining any primary game 
outcome of a flush. Accordingly, since the player has obtained a flush 
during play of the primary game not only does the player receive the 
reward therefor but also the secondary game is triggered. 
Triggering of the secondary game results in the processor issuing commands 
to display at the display 14 a plurality or field of second game choices 
34. It is to be understood that where the triggering event is based upon a 
primary game outcome, that triggering event can be selected as one or more 
outcomes such as obtaining a flush or better or four-of-a-kind during play 
of the video game, certain payoffs obtained during play of the video keno 
game or the arrangement of certain symbols during play of a electronic or 
electromechanical multiple reel slot machine. 
Additionally or alternatively, the triggering event 32' may be selected as 
an "Nth coin" event. As stated above, the processor is adapted to keep 
track of the wagers made during play of the primary game. The processor 
may be configured to accrue data representing the amount wagered until a 
predetermined, accrued amount is reached. Thereafter the next, or Nth, 
coin or wager made at the device 10 will constitute the triggering event 
to initiate play of the secondary game. If the game requires a maximum 
wager to participate in the secondary game, the Nth coin would be the next 
maximum wager. 
Alternatively, the triggering of the secondary game may be based upon time. 
For example, from the last play of the secondary game, the processor may 
maintain by internal clock means, a chronological record until a 
pre-determined time is reached. When that time is reached, regardless of 
the outcome obtained during play of the primary game, the secondary game 
will be triggered for play by the player. 
Alternatively, any combination of primary game outcome, Nth coin or time 
may be used as a triggering event. For example, if a time parameter is 
selected but an Nth coin is wagered before the selected time, the 
secondary game would be initiated. 
Other parameters could be selected for triggering the second game. For 
example, some casinos have player tracking systems which track the 
player's wagering history at the gaming machines. Typically the player is 
issued an identification card which they insert into a card reader at 
their machine and signals are sent to a host processor which maintains an 
account for that player and, by various means, tracks the amount wagered 
by the player over time. Typically these systems are used to provide cash 
or other awards to players depending upon the player's account of wagering 
history. According to this embodiment, a triggering event may be selected 
by the player's account reaching a certain level. 
As can be understood, any one or combination of triggering events can be 
selected. 
Returning to the drawings, in the preferred embodiment, the triggering 
event is selected by the player obtaining a flush during play of the 
primary game of video poker. As shown in FIG. 4, when a triggering event 
32 has occurred, the processor is controlled to select at 36 from a stored 
set of values 38 for play of the secondary game hidden values. The 
processor also, as shown in FIG. 2, controls the display 14 to display at 
37 a plurality or field 39 of second game choice symbols 40 at the display 
14. As shown in FIG. 2, the symbols 40 may be backs of playing cards, 
stars, squares, logos or other symbols. According to the secondary game, 
the symbols 40 represent the selected hidden values. 
The player to play the secondary game, by using the touch screen device 16, 
selects at 41 a plurality of symbols from the displayed field 39 of 
symbols 40. According to the embodiment shown in FIG. 2, the secondary 
game requires the player to select five symbols 40 in an attempt to 
assemble a winning poker hand. The player simply touches the touch screen 
device 16 over the display 14 where the chosen selection resides. As the 
player selects the symbols, the hidden values as selected at select 36 are 
displayed. When all required symbols 40 have been selected, the revealed 
values represent the outcome for the secondary game. 
When the outcome of the secondary game has been determined, the secondary 
game outcome is compared at 43 to a processor data structure storing data 
representing secondary game winning outcomes 42 to determine if the player 
has obtained indeed a winning outcome. Winning outcomes for the secondary 
game, which is based upon assembling of poker hands, may be according to 
Table 2.

If the player has obtained a secondary game winning outcome as compared at 
43, the reward at 44 is issued and paid out at 45 to the player either by 
the device 10 dispensing coins into the coin tray 22 or by accumulating 
credits at credit location 20. If the secondary game winning outcome is 
not a winning outcome, no reward is issued. Thereafter the method and 
system returns the player to play the primary game to obtain the next 
outcome. 
If the secondary game results in the issuance of a reward to the player, 
that reward is issued in addition to any reward the player received during 
play of the primary game. For example, according to the example shown in 
FIGS. 1 and 2, the player would receive a reward of, for a maximum wager 
of five coins, 250 coins for obtaining a straight flush and an additional 
1,000 coins for obtaining four-of-a-kind, four Aces. Accordingly, the 
player would receive a total reward of 1,250 coins. 
As can be appreciated, the player, by participating in the secondary game, 
does not risk the reward that they obtain from playing the primary game. 
Furthermore, the secondary game provides the player with choice options. 
This contributes to the excitement of the game. Furthermore, by providing 
this secondary game according to the present invention, large rewards can 
be offered which, as shown in Table 2, can amount to a million coins. 
With reference to FIG. 3, a further embodiment of the present invention as 
shown. Like components bear like reference numbers. 
According to this embodiment, when the triggering event 32 occurs, the 
processor is adapted at select 36 to select the outcome which will be 
obtained during play of the secondary game. According to this embodiment, 
the data structure stores data representing hidden values of probability 
weighted outcomes at 46. For example, the secondary outcome may be 
pre-selected 46 such that the player obtaining a pair of jacks or better 
will occur 30% of the time, 3 of a kind 15% of the time, with a royal 
flush occurring less than 1% of the time. The processor is then adapted at 
select 36 to randomly select from these weighted probabilities the 
ultimate outcome for the secondary game. Thus, during play of the 
secondary game, the player may be assured of obtaining a winning outcome, 
however the probabilities are more likely that the winning outcome will be 
a pair of jacks or three-of-a-kind or the like. Once the selection is 
made, at display 37, the secondary field of choice symbols is displayed, 
as suggested in FIG. 2, enabling the player to make choices. The player 
then touches the displayed symbols 40 which in turn prompt the processor 
to reveal the pre-selected values based upon the random selection form the 
probability weighted values. The weighted probability set of values 38 may 
include losing outcomes as well. If the player has obtained a winning 
outcome, at 44, their reward is added to any reward that was obtained 
during play of the primary game. 
While I have shown and described certain embodiments of the present 
invention it is to be understood that it is subject to many modifications 
without departing from the spirit and scope of the claims set forth 
herein. For example, as described above, the primary game may be any 
heretofore known or to be developed primary game by which a player makes a 
wager and obtains a primary game outcome. Furthermore, while FIG. 2 shows 
that the field of game choice symbols 40 is a 5.times.5 matrix, any 
suitable number of game choice symbols or arrangement can be used. For 
example, the secondary game may be presented as a pictorial display such 
as a house by which the player selects locations in the house which reveal 
hidden values. Alternatively, the pictorial display could be an automobile 
offering the player the choice symbols of selecting locations on the 
automobile. 
Further, the selected hidden values need not be faces of playing cards. 
They may be numbers which must be matched or add-up to a certain number or 
graphical representations which must conform to the one or more 
pre-determined secondary game winning outcomes. 
Still further, in play of the secondary game, one or more values may be 
initially displayed with the player having to select a plurality to 
complete the outcome. For example, when the secondary game is initially 
displayed upon the occurrence of the selected triggering event, the 
display may show three cards to a royal flush requiring the player to make 
two selections to try to complete the hand.
