Number guessing quiz online
Chuyka is a party quiz where the answer is always a number. “How many bones are in the human body?” Everyone types a guess, and the closest answers score points. You don’t need to know the exact answer — the best sense of scale wins.
Create a free room →How to play
- The host creates a room and picks a question pack: from history and science to movies, food and space.
- Players join with a code or QR code, pick a nickname and see questions in their own language.
- Everyone enters a number, then the correct answer is revealed with a fun fact. A champions’ table wraps up the night.
How scoring works
The closest answer gets 3 points, the next closest 2, the third 1. Equal error means equal points. The furthest answer gets a “booby prize” 🙈 — the group can come up with a funny forfeit.
