What it is
Twenty is a Twenty Questions game by Charlie's Games, played in the browser. Think of something and let the AI ask questions until it guesses, or swap roles and ask your own questions to find the answer the AI is hiding. There's also a daily puzzle, a timed mode and rooms for up to 8 players. The author's page says the design, code and testing were done by the Hark AI agent, and the in-game answers and guesses come from Google Gemini. Your opponent is the AI itself, which is what sets it apart from an ordinary guessing game.
Who it's for: Anyone who likes riddles and quizzes and wants to match wits with an AI.
Before you start: It's free. The author says it works on phones and desktop. There's a global leaderboard, XP and achievements. The questions and answers you type are sent to Google Gemini, and the author doesn't say how they're stored or deleted. The page is in English.
