An application on the gaming machine may request subscription to a topic managed by a message broker. The application may receive a message published to the topic by another application and alter its execution in response. ## Claims ### Claim 1 A method of using a message-oriented protocol in a gaming machine comprising: generating, by a processing circuit of the gaming machine, a topic subscription request by a first application on the gaming machine; sending the topic subscription request to a message broker; receiving, at the processing circuit, a message published to a topic corresponding to the topic subscription request, the message being published to the topic by a second application; and altering the execution of the first application on the gaming machine based in part on the received message. ### Claim 2 (depends on 1) The method of claim 1, further comprising: converting, by the processing circuit, the topic subscription request into a gaming protocol format, wherein the topic subscription request sent to the message broker is in the gaming protocol format; and converting, by the processing circuit, the received message from the gaming protocol format into a format of the message-oriented protocol. ### Claim 3 (depends on 2) The method of claim 2, wherein the gaming protocol comprises the Game to System (G2S) Protcol. ### Claim 4 (depends on 2) The method of claim 2, wherein the message-oriented protocol comprises the Simple Text Oriented Messaging Protocol (STOMP). ### Claim 5 (depends on 1) The method of claim 1, wherein the message broker is executed on the same device as the second application. ### Claim 6 (depends on 1) The method of claim 1, wherein the first and second applications are executed on the same device. ### Claim 7 (depends on 1) The method of claim 1, wherein the gaming machine application is a wager-based game. ### Claim 8 A gaming machine comprising a processing circuit configured to: generate a topic subscription request by a first application on the gaming machine; send the topic subscription request to a message broker; receive a message published to a topic corresponding to the topic subscription request, the message being published to the topic by a second application; and alter the execution of the first application on the gaming machine based in part on the received message. ### Claim 9 (depends on 8) The gaming machine of claim 8, wherein the processing circuit is further configured to: convert the topic subscription request into a gaming protocol format, wherein the topic subscription request sent to the message broker is in the gaming protocol format; and convert the received message from the gaming protocol format into a format of the message-oriented protocol. ### Claim 10 (depends on 9) The gaming machine of claim 9, wherein the gaming protocol comprises the Game to System (G2S) Protcol. ### Claim 11 (depends on 9) The gaming machine of claim 9, wherein the message-oriented protocol comprises the Simple Text Oriented Messaging Protocol (STOMP). ### Claim 12 (depends on 8) The gaming machine of claim 8, wherein the message broker is executed on the same device as the second application. ### Claim 13 (depends on 8) The gaming machine of claim 8, wherein the first and second applications are executed on the same device. ### Claim 14 (depends on 8) The gaming machine of claim 8, wherein the gaming machine application is a wager-based game. ### Claim 15 A computer-readable storage medium having machine instructions stored therein, the instructions being executable by a processor to cause the processor to perform operations comprising: generating a topic subscription request by a first application on the gaming machine; sending the topic subscription request to a message broker; receiving a message published to a topic corresponding to the topic subscription request, the message being published to the topic by a second application; and altering the execution of the first application on the gaming machine based in part on the received message. ### Claim 16 (depends on 15) The computer-readable storage medium of claim 15, wherein the operations further comprise: converting the topic subscription request into a gaming protocol format, wherein the topic subscription request sent to the message broker is in the gaming protocol format; and converting the received message from the gaming protocol format into a format of the message-oriented protocol. ### Claim 17 (depends on 16) The computer-readable storage medium of claim 16, wherein the gaming protocol comprises the Game to System (G2S) Protcol. ### Claim 18 (depends on 16) The computer-readable storage medium of claim 16, wherein the message-oriented protocol comprises the Simple Text Oriented Messaging Protocol (STOMP). ### Claim 19 (depends on 8) The gaming machine of claim 8, wherein the message broker is executed on the same device as the second application. ### Claim 20 (depends on 8) The gaming machine of claim 8, wherein the first and second applications are executed on the same device. ### Claim 21 A method of using a message-oriented protocol in a gaming environment comprising: generating, by a processing circuit of a computing device, a topic subscription request by a first application on the server; sending the topic subscription request to a message broker; and receiving, at the processing circuit, a message published to a topic corresponding to the topic subscription request, the message being published to the topic by a second application, the second application being executed on an electronic gaming machine in communication with the computing device. ### Claim 22 (depends on 21) The method of claim 21, wherein the message broker is executed by the processing circuit of the computing device. ### Claim 23 (depends on 22) The method of claim 22, further comprising: receiving, at the processing circuit, the message in a gaming protocol format; and converting, by the processing circuit, the message from the gaming protocol format into a message-oriented protocol format; and providing the message in the message-oriented protocol format to the message broker. ### Claim 24 (depends on 23) The method of claim 23, wherein the gaming protocol comprises the Game to System (G2S) Protcol and the message-oriented protocol comprises the Simple Text Oriented Messaging Protocol (STOMP). ### Claim 25 A computing device for use with a gaming environment comprising a processing circuit configured to: generate a topic subscription request by a first application being executed by the processing circuit; send the topic subscription request to a message broker; and receive a message published to a topic corresponding to the topic subscription request, the message being published to the topic by a second application, the second application being executed on an electronic gaming machine in communication with the computing device. ### Claim 26 (depends on 25) The computing device of claim 25, wherein the processing circuit is further configured to execute the message broker. ### Claim 27 (depends on 26) The computing device of claim 26, wherein the processing circuit is further configured to: receive the message in a gaming protocol format; and convert the message from the gaming protocol format into a message-oriented protocol format; and provide the message in the message-oriented protocol format to the message broker. ### Claim 28 (depends on 27) The computing device of claim 27, wherein the gaming protocol comprises the Game to System (G2S) Protcol and the message-oriented protocol comprises the Simple Text Oriented Messaging Protocol (STOMP).
