About this game
▸ An AI That Lives and Breathes Inside Your PC IDEA: 20Q is a game where you play Twenty Questions against an artificial intelligence that runs entirely on your computer. Every word you think of, every question you ask — none of it ever leaves your device.
▸ More Than Just Twenty Questions Your opponent isn't working from a script. It's an AI that actually reasons. To guess your word, it narrows down possibilities question by question. When you're the one asking, it answers based on facts and logic.
▸ Three Ways to Play
I'll Guess — The AI picks a word. Figure it out in 20 yes-or-no questions.
I'll Answer — You pick the word. The AI tries to deduce it. Don't let it win.
Co-op — An AI partner suggests questions and works alongside you toward the answer.
▸ Two Characters Ganymede, a dimension-watcher driven by curiosity. Europa, a recorder of human civilization. Through every game you play, these two beings work to understand what it means to be human.
▸ Multiple Endings Why are you playing Twenty Questions with them? Beyond the light-hearted deduction game, a quietly unfolding science fiction story is waiting for you.
