Play a strategy game about the AI race where you govern the US or China through 2030.

I made a strategy game where you play the US or China through the AI race, 2026 to 2030, sixteen quarterly turns in the browser. One run takes about half an hour. At the start, the game seals two dice you never get to see. Inside: how hard alignment really is, and how fast takeoff compounds. You get eval reports, but only as ranges, and they flatter you most exactly when your systems are least aligned. At the end you get a debrief which shows what your evals said each quarter and also what was actually true. I lost every run I played myself so far. Every number in the game is source-backed or a labeled design choice. Some of them are wrong somewhere. There is an issue template for challenging a number with a better source, and the better source wins. No accounts, no tracking, no server, works offline after first load. AGPL, nonprofit. Cards and parameters are plain JSON. Contribution is possible without writing code. Would like to have your thoughts if it is fun to play, how you lik

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
