The AI hides a word. Ask yes/no questions and guess it in 20. It never lies.
Askle is 20 Questions the way it should be: you ask, the AI answers yes or no, and it never contradicts itself.
The AI picks a secret word from a category. You have 20 yes/no questions to figure it out. Every answer is judged against the actual word, so "Is it alive?" and "Is it a machine?" can never both be yes. No tricks, no guessing on the AI's side — the logic always holds.
HOW TO PLAY
• Pick a category: animals, food, objects, places and more
• Ask anything that can be answered yes or no
• Type your guess whenever you're sure — a correct guess wins instantly
• Need help? Take a hint (category, length, first letter)
MODES
• Daily word — one word for everyone, once a day. Compare your score with friends and keep your streak
• Random — endless practice in any category
• Challenge a friend — you pick the word, send a link, they have 20 questions to crack it
WHY ASKLE
• Consistent answers. Every yes/no is checked against the real word, not made up on the fly
• Fast. Answers come back in about a second
• 6 languages: English, 한국어, 日本語, Português, Español, Bahasa Indonesia — with a word list built for each language
