SYSTEMS AND METHODS FOR FACILITATING GAMEPLAY WITHIN MESSAGING FEEDS

1. A non-transitory computer-readable storage medium having instructions embodied thereon, the instructions being executable by a computing platform including one or more physical processors to perform a method for facilitating gameplay within a messaging feed of a messaging application, the method comprising: presenting a messaging interface, the messaging interface including an entry field and a communication field, the entry field displaying messaging content available for entry and/or selection by users, the communication field displaying a messaging feed that reflects a communication session between the computing platform and one or more other computing platforms, such presentation of the messaging feed includes messaging content previously entered and/or selected by a first user through the entry field and messaging content previously entered and/or selected by one or more other users through the one or moreother computing platforms; receiving entry and/or selection of first messaging content bythe first user through the entry field; updating the messaging feed in the communication field to present the first messaging content; and wherein the messaging content available for entry and/or selection by the first user includes one or more game icons, wherein entry and/or selection of a game icon effectuates presentation of a corresponding game within the messaging feed presented on the computing platform, such that by virtue of the first messaging content comprising a first game icon, the updating comprises presenting a first game within the messaging feed to facilitate participation by the first user in the first game, the first game in the messaging feed comprising a first instance of the first game icon. 9. A system for facilitating gameplay within messaging feeds displayed on computing platforms, the system comprising: one or more physical processors configured by computer-readable instructions to: receive messaging information describing messaging content entered and/or selected by users through computing platforms associated with communication sessions, the messaging content entered and/or selected by users via messaging interfaces presented at the computing platforms, including receiving first messaging information describing first messaging content entered and/or selected by a first user through a first computing platform, the first computing platform associated with a first communication session, wherein the first computing platform is configured to present a first messaging interface, thefirst messaging interface including a first entry field and a first communication field, the first entry field displaying messaging content available for entry and/or selection bya first user, the first communication field displaying a first messaging feed that reflects the first communication session, such presentation of the first messaging feed including messaging content previously entered and/or selected by the first user through the firstentry field and messaging content previously entered and/or selected by a second user through the second computing platform associated with the first communication session; effectuate updates of messaging feeds of the messaging interfaces presented on the computing platforms based on the received messaging information, the updates corresponding to presenting messaging content in the messaging feeds, including effectuating a first update of a second messaging feed presented on the second computing platform based on the received first messaging information, the first update corresponding to presenting the first messaging content in the second messaging feed; and wherein the messaging content available for entry and/or selection by the users includes one or more game icons, wherein entry and/or selection of a game icon effectuates presentation of a corresponding game within the messaging feeds presented on the computing platforms, such that by virtue of the first messaging content comprising a first game icon, the first update comprises effectuating presentation of a first game within the second messaging feed to facilitate participation by the second user in the first game, the first game in the second messaging feed including an instance ofthe first game icon. 14. A computer-implemented method of facilitating gameplay within messaging feeds of messaging applications, the method being implemented in a computer systemincluding one or more physical processor and storage media storing computer-readable instructions, the method comprising: receiving messaging information describing messaging content entered and/or selected by users through computing platforms associated with communication sessions, the messaging content entered and/or selected by users via messaging interfaces presented at the computing platforms, including receiving first messaging informationdescribing first messaging content entered and/or selected by a first user through a first computing platform, the first computing platform associated with a first communication session, wherein the first computing platform is configured to present a first messaging interface, the first messaging interface including a first entry field and a first communication field, the first entry field displaying messaging content available for entry and/or selection by a first user, the first communication field displaying a first messaging feedthat reflects the first communication session, such presentation of the first messaging feed including messaging content previously entered and/or selected by the first user through the first entry field and messaging content previously entered and/or selected by a second user through the second computing platform associated with the first communication session; and effectuating updates of messaging feeds of the messaging interfaces presented onthe computing platforms based on the received messaging information, the updates corresponding to presenting messaging content in the messaging feeds, including effectuating a first update of a second messaging feed presented on the second computing platform based on the received first messaging information, the first update corresponding to presenting the first messaging content in the second messaging feed; wherein the messaging content available for entry and/or selection by the users includes one or more game icons, wherein entryand/or selection of a game icon effectuates presentation of a corresponding game within the messaging feeds presented on the computing platforms, such that by virtue of the first messaging content comprising a first game icon, the first update comprises effectuating presentation of a first game within the second messaging feed to facilitate participation bythe second user in the first game, the first game in the second messaging feed including an instance of the first game icon. 19. A system for facilitating group gameplay within messaging feeds of messaging applications, the system comprising: one or more physical processors configured by computer-readable instructions to: receive entry and/or selection of messaging content, the messaging content associated with communication sessions between computing platforms, the messaging content entered and/or selected by users via messaging interfaces presented at the computing platforms, wherein: the messaging content is presented in messaging feeds of the messaging interfaces, and the messaging content includes group gameplay icons that when entered and/or selected effectuate group gameplay between users ingroups; effectuate presentation of games within the messaging feeds in accordance with group gameplay between users, such that responsive to receiving entry and/or selection of a first group gameplay icon by a first user via a first computing platform, first group gameplay is effectuated between the first user and a second user such that a first game is presented on a first messaging feed on the first computing platform, and a second game is presented on a second messaging feed on a second computing platform associated with the second user, wherein the first computing platform and second computing platform are associated with a first communication session; determine outcomes of group gameplay based on outcomesof the games played by individual users in the groups, such that a first outcome of the first group gameplay is determined based on a second outcome of the first game played by the first user and a third outcome of the second game played by the second user; and effectuate presentation of determined group gameplay outcomes on the messaging feeds associated with users in the groups, such that the first outcome is presented on the first messaging feed and the second messaging feed.
