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), with UPSC CSAT and State PSC on the roadmap. Pick the exam you’re preparing for when you start and the daily tunes its framing to it.
Is Deduce only seating-arrangement puzzles?
No. Today the daily flagship is a seating/arrangement puzzle — the highest-weight and toughest reasoning topic in banking, where most aspirants lose the most marks, so a daily workout pays off most there. Under the hood it’s a general reasoning engine: circular seating, scheduling, ordering, blood-relations, direction and data sufficiency share the same machinery and roll out as daily challenges. SSC/Railway aspirants get series, coding-decoding, syllogism and classification. Pick your exam at sign-up and the daily tunes to it.
How is this different from Testbook, Smartkeeda or BYJU’S?
Those are question banks and courses — great for learning theory. Deduce is a daily habit: a fresh, server-checked, single-solution reasoning puzzle every day with a streak and leaderboard. You can’t cram the answer — you build the skill. Use both.
Will it actually help my exam?
We target the section you lose the most marks on first (banking: puzzles + data sufficiency), with a step-by-step solution after every round and difficulty that adapts. It’s exam-pattern reasoning, daily, in about five minutes — built for the consistency that cracks reasoning.
Do you cover non-verbal / figure-based reasoning?
Not yet — those are image-based and we only ship puzzles we can validate to a single solution. We focus where a fresh daily puzzle beats a static bank; non-verbal practice is better served by a question bank for now. We’d rather be honest than overclaim.
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.
