About this gig

Need a playable ad for your mobile game? I build custom HTML5 playable ads with real gameplay, not a template.


I'm a game developer working in PixiJS and TypeScript. I recreate the core moment of your game: a guided first move, clear progress, a reward and an end card with a call to action.


What you get:

  • A light single-file HTML5 build
  • Portrait and landscape layouts
  • A build for your ad network (AppLovin, Unity, Meta, Google, Mintegral, ironSource...), with MRAID where the network needs it
  • A preview to test before delivery
  • Clear written updates

What I need from you:

  • A short brief (goal, target network, size limit)
  • A gameplay video or screenshots
  • Your art, logo and fonts (and the right to use them)

Not included: campaign management, media buying, new art from scratch, real-money gambling features.


The images show my own portfolio concepts (match-3, tower defense, slot-style), not client campaigns.


Not sure which package fits? Send me a message with your game and I will suggest the simplest option.
