A friend taught me a Slovenian card game two days ago. GPT-5.6 Sol helped me turn our argument into an AI opponent. Two days ago, a friend taught me Sedmice, a traditional card game we play in Slovenia. The rules are simple, but we quickly got into an argument about the best moves. Naturally, I decided the reasonable way to settle it was to build an AI opponent. I wrote out the rules, project specification, architecture, and implementation details, then handed the logic to GPT-5.6 Sol. Ab

create multiplayer apps that you can play with friends or share with coworkers. Like Slido/Kahoot but you can create your own one with AI.

Play a multiplayer strategy game where you run a corporation across the Solar System.

🚀 I'm building Solar Empire — a browser MMO strategy set in one seamless, living Solar System. And here's the twist: the entire prototype was pair-built with Claude Fable 5. The game. You run a private corporation. You start on Earth, where the geology is hidden — buying a hex IS the prospecting, so every claim is a gamble. Power plants feed mines, smelters feed factories, and a player-driven market ties it all together. Then you go to space. A rocket is assembled at your factory, rolls out to your spaceport pad, and launches — gravity-turn ascent, stage separation, the works. The Moon it flies to is actually moving: transfer windows change your fuel bill in real time, just like real orbital mechanics. The planets are real NASA/USGS maps. Weather is simulated once for everyone — the storm cutting your solar output is the same storm your rival sees from orbit. Abandoned bases decay into ruins that other players can scavenge, so the map never clogs up. The pro
