Description

SYSTEM AND METHOD FOR PLAYING A RUMMY-BASED CARD GAME

TECHNICAL FIELD

The invention relates to a rummy-based card game, and its related computer-implemented system and method.

BACKGROUND

Card games, such as blackjack, Rummy, and bridge are popular and commonly played in casinos, amusement arcades, at homes, etc., as table games or computer-or mobile-games. Card games are typically played with a deck of cards. A card deck typically contains 54 cards, including two joker cards, and fifty-two cards equally divided into four suits (clubs, diamonds, hearts, spades) each with thirteen cards (2, 3, 4, 5, 6, 7, 8, 9, 10, Jack, Queen, King and Ace) . Depending on the type of card game, different number of cards or different number of decks of cards may be used. For example, in some card games the jokers are not used; in some other card games, two decks of cards, with or without jokers, may be used.

These card games are usually fun and entertaining, especially to players who are new to the game. However, sometimes, a card game can become less fun to a player, when the game is played repeatedly over time, when the player becomes familiar with the game strategy or game logic, or when the player struggles to win the game after multiple plays.

Attempts have been made to make card games more fun. US2010/0173688A has disclosed a computer-implemented method for enhancing the strategy factor in card games by allowing other players of the card game to see one or more cards held by the opponents which are otherwise normally concealed. While the method disclosed does potentially improve the variability of the game, such a simple game modification is unlikely sufficient to provide the game with a more lasting appeal to the players. There remains a great demand for card games (especially those implemented on electronic devices) that are fun, stimulating, interactive, intuitive to control, and with improved variability, to provide improved enjoyment and entertainment.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Figure 1 shows a basic configuration of a rummy-based card game 100 in one embodiment of the invention. In this embodiment, the game is a table game that can be played by 2 to 5 players, using two decks of cards. In one example, the game can be played with 107 cards: three joker cards plus two sets of fifty-two cards (one hundred and four cards in total) that are equally divided into four suits (clubs, diamonds, hearts, spades) each with thirteen cards (2, 3, 4, 5, 6, 7, 8, 9, 10, Jack, Queen, King and Ace) . In this game, the number cards have their respective face value (the card “2” has a value of 2, etc. ) , the “Jack” has a value of 11, “Queen” a value of 12, “King” a value of 13, “Ace” a value of 1 or 14. The “Joker” is used as a wild card.

At the beginning of the game, each player is given the same predetermined number of cards (e.g., 10 cards) . The cards are given to the players in random, or pseudorandom in a sense that the player considers the cards to be given in random. The cards held by individual players are arranged “face-down” , such that the contents of the cards are unknown to the other players (but the number of cards remaining is) . After initially distributing cards to the players, the remaining cards are placed in a stockpile “face-down” (i.e., card contents concealed) . The stockpile of cards is placed in a “stockpile area” 102 to be drawn by the players during the game. One card from the stockpile of card is initially drawn and revealed, placed in a “discard area” 104. The game can begin from any player, then either clockwise or anticlockwise through each and every other player, then back to the player, and on and on, until the game ends. The general object of the game is to play the cards according to predetermined game rules, until no cards are left in hand. The first player to complete playing all of the cards, i.e., who have no more cards left in hand, would become the winner.

At each turn of play, each player can perform one of the following actions:

(1) discard one card in hand, place that card in the “discard area” 104, and get a card from the stockpile (usually the top card)

(2) discard one card in hand, place that card in the “discard area” 104, and exchange for most recently discarded card in the “discard area” 104

(3) (a) play one or more runs of cards in hand, each runs of cards including three or more cards of consecutive ranks in the same suit (the played cards will be placed in the “played area” (not shown) )

(b) play one or more sets of cards in hand, each sets of cards including three or four cards of identical rank in different suits (the played cards will be placed in the “played area” )

(c) play one or more cards in hand to be added to the sets or the runs of cards that have been played, while optionally, altering the order and sequence of the sets or runs of cards that have been played (in the “played area” )

At each round, actions (1) , (2) , and (3) are mutually exclusive. That is, only one of the three actions can be taken by the player. On the other hand, one or more of actions (3) (a) , (3) (b) , and (3) (c) can be taken at each round. Also, the “Joker” card is a wild card that can be used to complete runs and sets. For example, “Ace + 2 + Joker” of the same suit is a valid run. “Ace heart + Ace Spade +Joker” is a valid set.

One important rule of the game is that before any of the above actions can be freely taken, each player has to perform action (3) (a) first. In one embodiment, in this action, the combined value of the cards played has to be larger than a predetermined value (say, 30) . If, at the turn of play of the player, and the player has cards in hand that allows him/her to perform action (3) (a) (preferably “Joker” can be used) , then he/she may play those cards. Then, at each subsequent turns, the player can play the cards however he/she desires, taking one of actions (1) , (2) , and (3) . Otherwise, if, at the turn of the player, and the player has no cards in hand that allows him/her to perform action (3)(a) , then the only option available to the player at the turn is either action (1) or action (2) .

The game is considered ended when one of the following conditions occur:

(A) a player has shed or played all of the cards in hand, or

(B) the stockpile of cards have been drawn completely (none left) .

At the end of the game, the scoring is determined. Specifically, the scores are based on the values of cards remaining in hands of the other players. For example, if, at the end of the game when one player has played all of his/her cards, one other player remains in hand a “King” and a “5” , then his score is 13 + 5 = 18. The winner of the game or the series of games is the one who obtains the lowest score. In some cases, special scoring may apply. For example, if one player has played all of his/her cards, and one of the other players has not performed action (3) (a) , then the score of that player may be double of the value of the remaining cards in hand. Or, if one player has played all of his/her cards, and one of the other players has not played any cards from hand, then the score may be tripled of the value of the remaining cards in hand.

In one embodiment of the game, a set of cards providing special function, called a game tool, can be used to affect a status of the rummy-based card game. The game tool (card) may be used to alter one or more cards in a hand of cards of any players of the rummy-based card game, to suspend or temporarily suspend one round of game play of any players of the game, to alter scoring of any players of the game, to alter one or more cards that have been played or in the stockpile or in the “discard area” 104, etc.

Figure 2 is an illustration (e.g., screenshot) of a computer-implemented rummy-based card game 200 in one embodiment of the invention. The term “computer-implemented” is not intended to limit the implementation of the game to a specific type or form of computer. Instead, it is to make clear that the game is implemented electronically, not by a dedicated game set. The general game rules of this rummy-based card game are similar to the game rules of the game of Figure 1 and so will not be repeated. Cards played by the players are placed (virtually) in the “played cards area” 206. Cards discarded by the players are placed (virtually) in the “discard area” 204. The stockpile of cards to be drawn by the players is placed (virtually) in the “stockpile area” 202.

In Figure 2, the layout of the game includes additional elements not available in the game of Figure 1. As shown in Figure 2, on the top left corner, basic player information 220 is shown. This basic player information 220 including the game level of the player (dependent on the number of games played, winning percentage, etc. ) , the avatar of the player, the name (e.g., player-defined) of the player, the number of tokens/gems owned by the player (the tokens/gems can be purchased, earned through game play, etc., and can be used to purchase game tools, etc. ) . On the top right corner there are virtual buttons 230 to score list showing a player ranking by score, to task that a player can play to earn reward, gems, tokens, etc., to gift that a player can give (in the form of gems, tokens, etc. ) to any other players of the game, and to quit game.

Figure 2 also shows various additional game variation features. For example, on the right, there is shown a game clock 208. The game clock 208 is arranged to limit the player’s action time at each round such that the player has to choose to complete an action before the countdown of the clock ends, otherwise a random or default action (e.g., action (1) ) will be taken. A reward 210 may be provided to the player, e.g., when the player completes a particular tasks or sets of tasks. The reward may be a bonus game, a scoring bonus, a game tool, etc. The game tools 212 are provided on a side of the screen. The player can select the tools button to view the tools available to him and to use them. The game may also provide a “chat” function 240 to allow the player to communicate with other players in the game or in the game platform (not in the game in which the player in playing) .

Figure 2 also shows various additional game intuitiveness enhancing features. The panel 250 with “sort by runs” and “sort by sets” buttons enables the player to sort the cards by runs and by sets, respectively. A score gauge is provided to the player showing the total values of cards in hand. To play the cards, the user can select the cards then press “Play” . To undo any action, the player can press “Cancel” .

In some embodiments, the game could be played with different game difficulty levels. For example, the game could be played in basic mode, intermediate mode, and advanced mode. Each of these modes may impose different game rules on the players. For example, in basic mode, action (3) (a) can only be performed with three or more cards; in intermediate mode, (3) (b) can only be performed with four or more cards; in advanced mode, (3) (a) can only be performed with five or more cards. In another example, in basic mode, action (3) (a) can performed anytime; in intermediate mode, (3) (b) cannot be performed for a first predetermined number of rounds; in advanced mode, (3) (a) cannot be performed for a second predetermined number of rounds (larger than the first predetermined number of rounds) . The score determination scheme may be different for different modes.

In some embodiments, each player may have a player profile containing a selected character. The selection of characters can be performed every time before game play, or be performed with the user profile is set up. Each of the characters may have different “skills” or “properties” that provide different advantages (and dis advantages) in the game play. In one example the characters are based on superheroes. Superhero 1 may be able to gain more points for a card than the other characters; Superhero 2 may be able to discard and draw 2 cards in action (1) ; Superhero 3 may be able to discard and draw 2 cards in action (2) , etc. In one embodiment, the player may be able to purchase a special character with special “skills” or “properties” that provide further advantages in the game.

The introduction of different game difficulty levels, and different player selected characters, along with the game tools, substantially increase the variability and playability of the game. The entertainment value of the game (implemented electronically) is much improved compared with the games played by deck of cards.

Figure 3 shows a general method 300 for playing a rummy-based card game using an computing system with one or more computing devices. The method 300 begins in step 302, in which a game input for playing the game is received from a player of the game via an electronic device. Then, in step 304, a response (e.g., game output, game state change, etc. ) to be provided to the player based on the received game input is determined using one or more processors. Finally, in step 306, the determined response is provided at the electronic device to the player playing the game through the electronic device.

In step 302, the game input may include a command to sort, from a hand of cards of the player, one or more cards. The sorting could be based on value of the cards (ascending or descending order) , or based on the suits of the cards (e.g., suits order: clubs, then diamonds, then hearts, then spades) . The sorting could also be based on playable cards. Alternatively or additionally, the game input may be a command to play, from a hand of cards of a player: a run of cards including three or more cards of consecutive ranks in the same suit; a set of cards including three or four cards of identical rank in different suits; or one or more cards to be added to sets or runs of cards that have been played and revealed. Alternatively or additionally, the game input may be a command to exchange a card, i.e., to discard, from a hand of cards of a player, a card and then obtain a card from either a stockpile of concealed cards or obtain the most recently discarded card. Alternatively or additionally, the game input may be a command to alter the sets or runs of cards that have been played or revealed.

Additionally or alternatively, the game input may include a command to use a game tool during the game to affect a status of the game. The game tool may include, for example: a tool to alter one or more cards in a hand of cards of any players of the game, a tool to suspend or temporarily suspend game play of any players of the game, a tool to alter scoring of any players of the game, a tool to alter one or more cards that have been played and revealed, etc.

In one embodiment, in step 302, the game input (any of the above examples) can be received via a sensor of the electronic device.

One exemplary sensor is a motion sensor, in the form of a gyroscope, IMU, accelerometer, etc. The game input is based on the movement of the electronic device detected by the motion sensor. More specifically the game input may be dependent on an extent, direction, or number of times of translation and/or rotation of the electronic device, or the number of times of shaking of the electronic device. In one example, the motion sensor may determine number of shaking of the electronic device (e.g., portable electronic device in the form of a tablet, phone, watch, etc. ) . If the motion sensor detects one time of shaking within a predetermined time, then the electronic device would consider the game input as sorting the cards by runs (ascending order or descending order) . If the motion sensor detects two times of shaking within a predetermined time, then the electronic device would consider the game input as sorting the cards by sets (predetermined suit order) . If the motion sensor detects three times of shaking within a predetermined time, then the electronic device would consider the game input as drawing or using a game tool, or the electronic device would consider the game input as automatically playing cards to perform action (3) . If the motion sensor detects spinning of the device once (e.g., angular rotation of the device above a predetermined angle) , the electronic device would consider the game input as playing the cards (correspond to a card throwing gesture if physical cards are used) .

Another exemplary sensor is a proximity sensor, in the form of a thermal sensor, optical sensor, electromagnetic sensor, etc. The game input is based on detection of the proximity sensor. As an example, the game input is dependent on detection of presence of the player at the electronic device by the proximity sensor. In one example, if the proximity sensor determines that the player is not present for a predetermined of time (e.g., 15 seconds) , then the electronic device would consider the player as having left the game, and subsequently, the player would be kicked out of the game, or the player’s hand would be overtaken and be controlled by computer. Scoring may also be affected (penalty score given to player) .

In one embodiment, in step 302, the game input (any of the above examples) can be received via a touch-sensitive display of the electronic device. The game input can be provided by movement of a player’s finger on the touch-sensitive display. More specifically, the game input may be different depending on the speed of movement of a player’s finger on the touch-sensitive display, direction of movement of a player’s finger on the touch-sensitive display, and/or the number of fingers of the player on the touch-sensitive display. In one example, if the touch-sensitive display determines that the finger is moved away from the cards in hand towards the play area, then the electronic device would consider the game input as discarding the selected card. If the touch-sensitive display determines that the finger is moved away from the play area towards the cards in hand, then the electronic device would consider the game input as collecting a card or retrieving a card to hand.

In one embodiment, in step 302, the game input (any of the above examples) can be received via a camera of the electronic device. The game input can be provided by operation of the camera. In one example, the camera is arranged to take an image, and upon taking the image, the electronic device would determine whether the player is in the image. The electronic device would determine the game input as quitting the game if the image taken does not include the player. In another application, the camera can be used to take image of the player, or any objects, to customize the “Joker” card, or the pattern on the backside of the card. The images taken by the camera include real-time images captured on the fly, and may be a portrait of the player.

In one embodiment, in step 302, the game input (any of the above examples) can be received via a microphone of the electronic device. The game input can be provided by audio signals detected by the microphone. In one example, the microphone is arranged to detect control commands (speech) provided by the player, and the electronic device is arranged to determine a corresponding game input or game action based on the command detected . For example, the player may say “play” , which is picked up by the microphone, and then the electronic device would consider the game input as playing the cards (e.g., action (3) described above with respect to Figure 1) . Or the player may alternatively say “discard spade Ace” , which is picked up by the microphone, and then the electronic device would consider the game input as discarding the Ace of spade in exchange for a card from the stockpile.

In one embodiment, in step 304, the determination of game output includes determination of validity of game input based on the game rules of the game (such as those rule described with respect to Figure 1) . Upon determining that the game input is invalid, the method 300 may include providing to the player, at the electronic device, an indication to provide another game input. For example, if a player selects and then attempts to play those cards that are neither sets nor runs, then the one or more processors detect this violation of game rules and prompt the player to provide a valid game input.

Although not shown in Figure 3, the method 300 may further include determining, using the one or more processors, the end of the game. As previously explained, in one game rules embodiment, the game ends when a player of the game has shed all cards in hand or when the stockpile of concealed cards has been exhausted (all drawn) . After end of the game, an amount of score may be determined based on the cards remaining in hand of the respective players. As explained above, a larger score may represent a bigger loss. In some embodiments, after scoring is determined, the method 300 includes updating game statistics associated with the respective players. The game statistics may include cumulative game scores, number of games played, cumulative winning percentage, maximum game score achieved in a game. The cumulative game scores of a player can be used for purchasing or exchanging game tools.

In the method 300 of Figure 3, the one or more processors that perform step 304 may be distributively arranged at the electronic device and at one or more other electronic devices (e.g., a server) . Alternatively, the one or more processors may be arranged in the electronic device, preferably in the form of a portable computer, a smart phone, smart watch, or any portable IoT devices.

Figures 4A to 4C show some exemplar electronic devices that can be used to implement the game 200 of Figures 2 or the method 300 of Figure 3. In Figure 4A, the device is a smart phone or smart tablet 400A (depending on the scale) . In Figure 4B, the device is a handheld gaming console 400B. In Figure 4C, the device is a desktop computer 400C.

Figure 5 shows the basic architecture of a system 500 arranged for implementing the game 200 of Figures 2 or the method 300 of Figure 3. As shown in Figure 5, different electronic devices 400A-400C for playing the game can be connected with a gaming server 20 through a network 10 such as a cloud computing network. In one example, the electronic devices 400A-400C can be wirelessly linked together. In one embodiment, the server 20 provides the one or more processors for performing the method step 304 and for managing the game play of different players of a game. The players and hence the electronic devices 300A-300C can reside in different geographical locations (e.g., different cities, countries) . In one mode of operation, the server 20 may allow different players to compete with each other. In another mode of operation, the server 20 may allow a single player to play the game, by controlling other three players through artificial intelligence.

Figure 6 shows a schematic diagram of an exemplary information handling system 600 that can be used as a server 20, the electronic devices 400A-400C, or other information processing systems that can implement the rummy-based card game of the invention. The information handling system 600 may have different configurations, and it generally includes suitable components necessary to receive, store, and execute appropriate computer instructions, commands, or codes. The main components of the information handling system 600 are a processor 602 and a memory unit 604.

Preferably, the information handling system 600 further includes one or more input devices 606 such as a keyboard, a mouse, a stylus, an image scanner, a microphone, a tactile input device (e.g., touch sensitive screen) , an image/video input device (e.g., camera) , a sensor (e.g., proximity sensor, motion sensor) , etc. The information handling system 600 may further include one or more output devices 608 such as one or more displays (e.g., monitor) , speakers, disk drives, headphones, earphones, printers, 3D printers, etc. The display may include a LCD display, a LED/OLED display, or any other suitable display that may or may not be touch sensitive. The information handling system 600 may further include one or more disk drives 612 which may encompass solid state drives, hard disk drives, optical drives, flash drives, and/or magnetic tape drives. A suitable operating system may be installed in the information handling system 600, e.g., on the disk drive 612 or in the memory unit 604. The memory unit 604 and the disk drive 612 may be operated by the processor 602. The information handling system 600 also preferably includes a communication module 610 for establishing one or more communication links (not shown) with one or more other computing devices such as servers, personal computers, terminals, tablets, phones, or other wireless or handheld computing devices.

In one embodiment, some of these components may be connected through a network such as the Internet or a cloud computing network. A person skilled in the art would appreciate that the information handling system 600 shown in Figure 6 is merely exemplary and different information handling systems 600 with different form or configurations may be applicable to implement the game of the invention.

Figure 7 shows a method for operating a rummy-based card game using the system of Figure 5 in one embodiment. The rummy-based card game can be that described above. The method involves, initially at step 702, receiving a player input at the electronic device 400A-400C. The input may be provided by the player, by clicking on buttons on the touch-sensitive display screen of the device 400A-400C. The input may alternatively be provided by the player through any of the sensors of the device 400A-400C described above. For example, the input may be provided by the player shaking the

device

400A, 400B (detected by motion sensor) , tossing, translating, and/or rotating the device in predetermined way detectable by the device 400A-400C sensor. These tossing/translating/rotating gestures are preferably similar or identical to a real-life card playing gesture, as explained above. For example, swinging the

device

400A, 400B may correspond to playing a card or a set of cards. In another example, the player input can be provided by inaction of the player. If, at the turn of the player, the clocks runs down, and the player has still not yet provided any input or any recognizable input, then the player input would be considered as to discard a card in hand in exchange for a card.

In step 704, the device 400A-400C, based on the received player input, converts the player input into a game input. The term “game input” may refer to any input that affects the game, including input to play a card, to leave a game, to start a game, etc. The device 400A-400C is arranged with a list of player input –game input correlation. The correlation may be different for different state of the game. For example, rotating the device at the beginning of the game and rotating the device during a turn of play may correspond to different game inputs. The device 400A-400C may compare the received player input with the list to identify whether the received player input corresponds to any game input. If the player input is not recognizable, then the device 400A-400C will ignore the player input.

Once the player input is determined at step 704, then the device 400A-400C then provides the determined game input, or its related information, to the server 20 through the network at step 706. The communication can be wired or wireless.

The server 20, at step 708, processes the received determined game input and determine a response. In one example, the server 20 may determine whether the game input is valid, by comparing the game input with predetermined rules and logic. For example, the game input is to play a particular card, and the server 20 may determine that the card is playable or not playable according to the game rules. Having determined a response, at step 710, the server 20 sends the determined response to the device 400A-400C. The response may be one that the game input is executed, or a game action is taken. Alternatively, the response may be one that the game input is denied or a game action is not taken (e.g., because they do not conform to rules of the game) .

The device 400A-400C, upon receiving the determined response from the server 20, at setp 712, would provide an output or an indication to the user. For example, if the determined response is that the card is playable, then the device 400A-400C would display the card as being played, optionally along with an audible or tactile feedback. Alternatively, if the determined response is that the card is not playable, then the device 400A-400C would display a message saying that the input is invalid, or that a new game input is required, optionally along with an audible or tactile feedback.

At step 714, the server 20, upon providing the response to the device 400A-400C, would update the game state of the game. This step is crucial to ensure that the game information across all devices 400A-400C playing the same game are in synchronization, to order to allow the game to be properly played. In one example, the update of the game state would include update of the account, scoring, and like information of the player, update related to the game play (the cards, the game tools, the bonus game, etc. ) to reflect the latest action taken by the players, The server 20 would provide command, data, or information to the devices 400A-400C to ensure that the updated game state are properly reflected in the devices 400A-400C. In one example, if the server 20 loses connection with one of the device 400A-400C, it may temporarily take over control of the game play for that particular player (the device of whom has lost connection with the server) , through artificial intelligence, to replace the disconnected player with a game bot. The other players (still connected and playing) may or may not made aware of such temporary replacement.

In some other embodiments, unlike the one described with respect to Figure 7, the processing of the game input and the determination of the response is performed at the device 400A-400C locally. The results of the determined and executed response are transferred to the server 20 to update the game state, and to synchronize the game state across the devices 400A-400C playing the same game.

Although not required, the embodiments described with reference to the Figures can be implemented as an application programming interface (API) or as a series of libraries for use by a developer or can be included within another software application, such as a terminal or personal computer operating system or a portable computing device operating system. Generally, as program modules include routines, programs, objects, components and data files assisting in the performance of particular functions, the skilled person will understand that the functionality of the software application may be distributed across a number of routines, objects or components to achieve the same functionality desired herein.

It will also be appreciated that where the methods and systems of the invention are either wholly implemented by computing system or partly implemented by computing systems then any appropriate computing system architecture may be utilized. This will include stand-alone computers, network computers, dedicated or non-dedicated hardware devices. Where the terms “computing system” and “computing device” are used, these terms are intended to include any appropriate arrangement of computer or information processing hardware capable of implementing the function described. The “computing system” and “computing device” can be arranged at an entertainment center, gaming center, casino, or elsewhere.

It will be appreciated by persons skilled in the art that numerous variations and/or modifications may be made to the invention as shown in the specific embodiments without departing from the spirit or scope of the invention as broadly described. The described embodiments of the invention should therefore be considered in all respects as illustrative, not restrictive.

For example, one or more game rules of the rummy-card games may be changed, added, removed, etc., to vary the game. The number of players for the game can be any number larger than or equal to 2. The number of cards (or decks of cards) used and the format of cards used can be different, but preferably they are dependent on the number of players. Also, the cards need not be in four suits as in standard poker cards, but can be in two or more number of suits, represented by different symbols (not necessary clubs, hearts, etc. ) . The game could be a wagering game or a non-wagering game. The computer or computing system that is arranged to implement the game can have different configurations. The game may be one that is downloaded and played on a computing or electronic device alone by a single player (against computer opponents) , or may be an interactive game that can be played by different players for competition (not against computer opponents) .
