About this game
11 Seconds is a fast estimation quiz built around one simple rule: every answer is a number, and every question gives you 11 seconds.
No multiple choice. No slow setup. Read the prompt, trust your instinct, type your estimate, and see how close you were.
Play quick solo runs when you want a short session. Challenge friends in async duels. Enter ranked best-of-3 matchmaking and climb with an ELO rating. Track accuracy, streaks, categories, and past games so every round teaches you something for the next one.
What you can do in 11 Seconds:
- Play five-question solo runs
- Challenge friends in direct async duels
- Enter ranked best-of-3 matchmaking
- Climb leaderboards and compare scores
- Track accuracy, streaks, and category performance
- Review past games and improve over time
- Customize your profile, language, units, and theme
Why it stands out:
- Estimation gameplay instead of multiple choice
- Quick rounds built for mobile
- Solo, duel, and ranked modes with visible progress
- Stats and history that reward improvement
- A format that is easy to learn and hard to master
If you like trivia, numbers, prediction, and pressure-based decision making, 11 Seconds turns every round into a sharp test of instinct and accuracy. Start a run and see how close your estimate gets.
