As an early tester of Google Play Asset\nDelivery with their app\n[Puzzle Kids - Animals Shapes and Jigsaw Puzzles](https://play.google.com/store/apps/details?id=com.rvappstudios.jigsaw.puzzles.kids),\nthe team looked to optimize the size of their app, save money, and improve the\nuser experience by removing any friction when new asset packs would be required\nto be downloaded.\n\nWhat they did\n-------------\n\nWhen a user installs the Puzzle Kids app, a base level of content is included in\nthe initial install. As the user progresses through the in-app content, in order\nto access new levels and content, the user is required to download additional\ngame files. In order to deliver these additional content bundles, RV AppStudios\npays a third-party CDN to host the content and manage the delivery.\n\nPlay Asset Delivery was an appealing solution to help save CDN costs and improve\nuser performance. The integration process was very simple, taking the team less\nthan a day of development time to integrate the plugin into their existing\nprojects and to do the basic settings for the plugin. \"Google Play Asset\nDelivery met our expectations in a manner of cost, time, and effort to implement\nthe plugin\" said Vivek Dave, President at\n[RV AppStudios](https://play.google.com/store/apps/dev?id=7430005971129979939).\n\nThree custom delivery options are available with Play Asset Delivery:\nInstall-Time, Fast-Follow, and On-Demand. Install-Time allows game developers to\npackage up to 1GB of assets with their initial game download, while On-Demand\nand Fast-Follow allow developers to dynamically download assets post-launch (the\nlatter of which will be automatically triggered after installation). For Puzzle\nKids, the team utilizes the On-Demand delivery mode for their 17 asset packs.\n\nResults\n-------\n\nJust over 23MB of assets are delivered as players progress through the levels\nin Puzzle Kids. Using Play Asset Delivery's On-Demand mode, they saw a **4.7%\nincrease in 15-day retention and 21% reduction in crashes \\& ANRs**. Overall,\nthese changes helped improve the user experience by offering more stable,\ntransparent, and secure downloads, while also saving costs for RV AppStudios.\n\nGet started\n-----------\n\nGet started today by learning more about\n[Play Asset Delivery](/guide/app-bundle/asset-delivery)."]]
