A daily puzzle game where you spot AI-generated errors to sharpen critical thinking.

Play Parry — a 2-minute daily puzzle about catching AI's mistakes: spot the planted flaw, catch the answer that's lying to you I have been recently fascinated with puzzles as a way to help improve my BS-radar when using AI. I designed Parry to help with this - One puzzle a day - find the one flaw hidden in a confident paragraph, pick which of two AI answers actually helps you (one is subtly useless), call a claim true/false. Free, no account, nothing you input leaves your devi

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

MonopolAI: The Online Vibe Coded Board Game Monopoly, except the board is the AI industry. You acquire startups, build accelerator tiers, collect increasingly indefensible rent, and occasionally go to jail for insider trading. The computer opponents are Dario, Sam, and Elon. ( https://monopol.ai ) Recent bugs: Elon became trapped in an auction. An “Advance to NVIDIA” card froze the game. Players could not collateralize assets quickly enough while bidding. Someone was annoy

Create interactive games, polls, and quizzes with AI for presentations and events.
u/molefrog · Reddit
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. It can build polls, quizzes or games. had this idea for a while, the space isn't new and there is apps like Kahoot that presenters or educators use for polling/quizzes. however the templates are limited, so I decided to ship my own vibe-coding IDE for generating these. you just describe it for example "noise meter: people scream at their phon
