  • Patent number: 11969649
    Abstract: Prominent display of a targeted game in search results from a search within an online gaming platform. In some implementations, a server receives a search query from a device. The search query is executed against a data store of available games to obtain search results indicating a set of games. Based on one or more characteristics of the set of games, it is determined whether the search query is directed to a narrow search for a particular game in the set of games. In response to determining such a narrow search, the particular game is designated with a highlight indication, and the search results and highlight indication are transmitted to the device, causing display of a user interface that includes at least a portion of the search results. The highlight indication causes the device to display an identifier of the particular game as highlighted relative to other search results.

  • Patent number: 11144315
    Abstract: A technique determines a quality of an electronic game based at least in part on the time spent by a game developer to design the electronic game. While operating a game development tool during the design of the game, the number of actions taken using the game development tool are counted for a plurality of time frames. If the number of actions for any particular time frame meet a threshold number of actions, then a duration of that time frame is added to a value of a total developer time for the electronic game. Other time frames, in which the number of actions fails to meet the threshold, do not have their time frame durations added to the value of the total developer time. A higher quality rating corresponds to longer total developer time.

  • Patent number: 11144720
    Abstract: A method to determine a canonical title. The method includes identifying an original title for an original game. The method further includes removing from respective titles for a plurality of other games at least one of punctuation, one or more special characters, and emojis to determine corresponding canonical titles. The method further includes identifying a subset of canonical titles from the corresponding canonical titles that exceed a threshold similarity as compared to the original title. The method further includes associating an original history associated with the original game with the subset of canonical titles.

  • Publication number: 20210248162
    Abstract: Methods, systems, and computer readable media for mass parallel transfer of data from a source database to a target database are described. Tables of the source database to be copied to the target database are identified, a number of simultaneous connections that the source database supports is determined, a plurality of machines, based on the number, are launched, and the identified tables are respectively mapped to one or more machines of the plurality of machines. Subsequently, respective mapped table data is retrieved and sent by each of the one or more machines to the target database over a network.
