Delivered a flexible overlay system that supports up to 12 outcomes while maintaining clarity during twitch livestreaming compared to existing 2 outcome limitations.


Which enabled streamers to run more complex predictions without sacrificing viewer understanding or engagement

The problem

Twitch prediction overlays typically support only two outcomes, limiting how streamers can present more complex scenarios.


As outcomes increase in number, current overlays struggle to clearly communicate options and odds, making it harder for viewers to quickly understand and engage during a live stream.

Design an overlay that scales from 2 to 12 outcomes while remaining:


  • Easy to read in real time


  • Visually subtle


  • Clear across unpredictable livestream backgrounds

Designed a scalable overlay system that adapted based on the number of outcomes:


  • Simplified information as complexity increased


  • Prioritized essential data (outcomes + percentages)


  • Used grid and multi-screen layouts for higher counts (7–12 outcomes)

  • Designing for context matters as much as the interface itself
    Live stream environments are unpredictable, requiring solutions that remain clear under constantly changing conditions


  • Constraints drive better decisions
    Limited space and time forced a focus on what truly matters, strengthening information hierarchy and clarity


  • Collaboration improves outcomes

    Early and consistent communication with engineering helped surface limitations quickly and ensured solutions were both usable and feasible
