What is Deduce?
Deduce is a free, daily logic-reasoning puzzle built for Indian competitive-exam aspirants. Every day you get one fresh, server-validated puzzle — solve it in about five minutes, build a streak, and see where you rank.
It builds real exam skill on puzzles you can’t cram. Instead of grinding through hundreds of practice questions, you do one genuinely interesting, provably-correct puzzle a day — the same family of floor, seating and scheduling reasoning problems that show up in banking and SSC exams.
Play today’s puzzle →Who it’s for
Deduce is designed for aspirants preparing for India’s major competitive exams, with a focus on the reasoning section:
- Banking — IBPS PO & Clerk, SBI PO & Clerk, RRB, and other bank recruitment exams.
- SSC — SSC CGL, CHSL and related staff-selection exams.
- Anyone who wants a short daily brain workout in logical reasoning and deduction.
Why a daily puzzle works
- One a day beats a cram session. Spaced, consistent practice is how reasoning becomes fast and automatic in the exam hall.
- Streaks keep you honest. A visible streak turns "I'll study later" into a five-minute habit you actually keep.
- Real difficulty, fairly ranked. Timing and scoring are validated on the server, so the leaderboard reflects real solving — not a faked clock.
What kind of puzzles?
Each puzzle gives you a set of people and a set of positions — for example, five people living on the five floors of a building — plus a handful of clues. Your job is to use the clues to deduce the one and only arrangement that satisfies every constraint. Every puzzle is checked to have exactly one solution before it’s ever served, so there’s always a clean, logical path to the answer.

Start your streak →The other half of the paper
Deduce trains reasoning. The quantitative-aptitude section needs a different muscle — raw calculation speed against a clock — so it has its own daily from the same team: ComputePrep, a free timed drill across 21 quant kinds, from vedic-maths shortcuts to DI, quadratic comparison and probability. Same engine, same aspirants: Deduce asks you to be provably right, ComputePrep asks you to be right before the buzzer. Ten minutes covers both.
