Systems and methods for game state retention and continuation at electronic gaming machines
View Patent ↗An electronic gaming machine includes a display device and a processor configured to execute instructions stored in a memory, which when executed by the processor, cause the processor to generate a game-state-retention sign based upon a plurality of game variables representing a state of a wagering game, where the game-state-retention sign includes a first two-dimensional machine-recognisable image that encodes the plurality of game variables. When executed, the instructions also cause the processor to display the game-state-retention sign on the display device for image capture by a handheld player device, where the handheld player device is configured to display a game-continuation sign generated from the game-state-retention sign for resuming play of the wagering game.
1. An electronic gaming machine comprising:
a display device; and
a processor configured to execute instructions stored in a memory, which when executed by the processor, cause the processor to at least:
generate a game-state-retention sign based upon a plurality of game variables representing a state of a wagering game, the game-state-retention sign including a first two-dimensional machine-recognisable image that encodes the plurality of game variables; and
display the game-state-retention sign on the display device for image capture by a handheld player device, the handheld player device configured to display a game-continuation sign generated from the game-state-retention sign for resuming play of the wagering game.
2. The electronic gaming machine of claim 1 , wherein the instructions, when executed, further cause the processor to at least:
receive the game-continuation sign displayed by the handheld player device, the game-continuation sign including a second two-dimensional machine-recognisable image that encodes, at least, the plurality of game variables; and
resume play of the wagering game based upon the received game-continuation sign in response to receiving the game-continuation sign and based upon the plurality of game variables encoded in the game-continuation sign.
3. The electronic gaming machine of claim 1 , wherein the game-continuation sign is identical to the game-state-retention sign.
4. The electronic gaming machine of claim 1 , wherein the game-continuation sign is different from the game-state-retention sign, at least, in that the game-continuation sign includes at least one validation portion for validating that the game-continuation sign has not been tampered with.
5. The electronic gaming machine of claim 1 , wherein the instructions, when executed by the processor, further cause the processor to at least:
generate at least one encryption key to define a first portion of the game-state-retention sign; and
encrypt the plurality of game variables defining the state of the wagering game to further define a second portion of game-sate-retention sign.
6. The electronic gaming machine of claim 1 , wherein the instructions, when executed, further cause the processor to generate the game-state-retention sign based, at least in part, upon a title of the wagering game, whereby at least a portion of the game-state-retention sign identifies the title of the wagering game.
7. The electronic gaming machine of claim 1 , wherein the instructions, when executed, further cause the processor to at least generate the game-state-retention sign in response to receiving a player input to save the state of the wagering game.
8. A method of game state retention and game continuation in an electronic wagering game, the method comprising:
generating, by a processor of an electronic gaming machine, a game-state-retention sign based upon a plurality of game variables representing a state of a wagering game, the game-state-retention sign including a first two-dimensional machine-recognisable image that encodes the plurality of game variables; and
displaying, by the processor, the game-state-retention sign on a display device for image capture by a handheld player device, the handheld player device configured to display a game-continuation sign generated from the game-state-retention sign for resuming play of the wagering game.
9. The method of claim 8 , further comprising:
receiving by the processor, the game-continuation sign displayed by the handheld player device, the game-continuation sign including a second two-dimensional machine-recognisable image that encodes, at least, the plurality of game variables; and
resuming, by the processor, play of the wagering game based upon the received game-continuation sign in response to receiving the game-continuation sign and based upon the plurality of game variables encoded in the game-continuation sign.
10. The method of claim 8 , wherein the game-continuation sign is identical to the game-state-retention sign.
11. The method of claim 8 , wherein the game-continuation sign is different from the game-state-retention sign, at least, in that the game-continuation sign includes at least one validation portion for validating that the game-continuation sign has not been tampered with.
12. The method of claim 8 , further comprising:
generating, by the processor, at least one encryption key to define a first portion of the game-state-retention sign; and
encrypting, by the processor, the plurality of game variables defining the state of the wagering game to further define a second portion of game-state-retention sign.
13. The method of claim 8 , further comprising generating, by the processor, the game-state-retention sign based, at least in part, upon a title of the wagering game, whereby at least a portion of the game-state-retention sign identifies the title of the wagering game.
14. The method of claim 8 , further comprising generating, by the processor, the game-state-retention sign in response to receiving a player input to save the state of the wagering game.
15. A tangible, non-transitory, computer-readable storage medium having instructions stored thereon, which when executed by a processor, cause the processor to at least:
generate a game-state-retention sign based upon a plurality of game variables representing a state of a wagering game, the game-state-retention sign including a first two-dimensional machine-recognisable image that encodes the plurality of game variables; and
display the game-state-retention sign on a display device for image capture by a handheld player device, the handheld player device configured to display a game-continuation sign generated from the game-state-retention sign for resuming play of the wagering game.
16. The computer-readable storage medium of claim 15 , wherein the instructions, when executed, further cause the processor to:
receive the game-continuation sign displayed by the handheld player device, the game-continuation sign including a second two-dimensional machine-recognisable image that encodes, at least, the plurality of game variables; and
resume play of the wagering game based upon the received game-continuation sign in response to receiving the game-continuation sign and based upon the plurality of game variables encoded in the game-continuation sign.
17. The computer-readable storage medium of claim 15 , wherein the game-continuation sign is one of: i) identical to the game-state-retention sign, or ii) different from the game-state-retention sign.
18. The computer-readable storage medium of claim 15 , wherein the instructions, when executed, further cause the processor to:
generate at least one encryption key to define a first portion of the game-state-retention sign; and
encrypt the plurality of game variables defining the state of the wagering game to further define a second portion of game-sate-retention sign.
19. The computer-readable storage medium of claim 15 , wherein the instructions, when executed, further cause the processor to generate the game-state-retention sign based, at least in part, upon a title of the wagering game, whereby at least a portion of the game-state-retention sign identifies the title of the wagering game.
20. The computer-readable storage medium of claim 15 , wherein the instructions, when executed, further cause the processor to generate the game-state-retention sign in response to receiving a player input to save the state of the wagering game.
