Pickle Duo is a real-time, zero-setup 2D multiplayer Pickleball game that lets you instantly play against friends by connecting your mobile phone and laptop over local Wi-Fi.

“Translating a physical sport into simple 2D pixels was a really fun design challenge. What surprised me most was dealing with mobile latency—initially, network lag made the controls unplayable. It required some back-and-forth with Antigravity to debug the touch interactions and implement client-side prediction to fix the lag. But even with that troubleshooting, I was amazed by how incredibly fast”

“What surprised me was that making the board playable was the easy part—keeping two players in sync was the real challenge. Handling simultaneous moves, enforcing turns, and agreeing on rematches showed me how much coordination sits behind a simple multiplayer game.”
