Frequently asked questions
Is Deduce free?
Yes — completely free. You get one new puzzle per difficulty every day at no cost.
Which exams does Deduce help with?
It’s built for the logical-reasoning section of Indian competitive exams — especially banking (IBPS PO & Clerk, SBI PO & Clerk, RRB) and SSC (CGL, CHSL). The floor, seating and scheduling puzzles mirror the reasoning these exams test.
What kind of puzzle is it?
Each puzzle gives you people, a set of positions (such as floors of a building), and clues. You deduce the single arrangement that satisfies every clue. Every puzzle is validated to have exactly one solution before it’s served.
How do difficulty levels work?
Three ranked puzzles each day — Easy, Medium and Hard — and you can play one of each. Higher levels use more people and floors, so there’s more to eliminate before the unique answer.
How do streaks and the leaderboard work?
Solve the daily puzzle to extend your streak; miss a day and it resets. Your time and score are validated on the server, so the leaderboard ranks real solving. Sign in with Google to keep your streak across devices.
How many attempts do I get?
Three attempts per puzzle. After a wrong submission you’re told how many clues your arrangement violated, so you can fix it.
Can I install Deduce on my phone?
Yes — it’s a Progressive Web App. Open it in your mobile browser and choose “Add to Home Screen” to install it like an app, no app store needed.
Do I need to create an account?
No. Start playing immediately without signing up. Google sign-in is optional and only saves your streak across devices.
