Layer Playable v1

PLAYABLEFeaturedlayer-playable-v1

Layer Playable v1 from Layer is the first AI model purpose-built for generating playable ads — interactive mini-game experiences used in mobile user acquisition campaigns. Unlike traditional static or video ads, playable ads let potential players engage with a short, scaled-down version of a game’s core mechanics before installing, delivering up to 3× higher conversion rates and 30–40% better retention than standard formats. The model takes your existing game assets — characters, backgrounds, UI elements, and reward screens — and composes them into a self-contained HTML5 playable unit ready for deployment across major ad networks. Designed for UA creative teams producing at scale, it dramatically reduces the turnaround from concept to live playable, enabling rapid A/B testing of gameplay hooks, difficulty curves, and visual themes.
