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 exam-pattern reasoning that shows up in banking and SSC papers — floor, seating and scheduling arrangements one day, syllogisms, data sufficiency, coding-decoding or series the next, rotating across 27 formats.
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?
The daily rotates across 27 exam-pattern formats in two families. On board days you get 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, and you deduce the one and only arrangement that satisfies every constraint. On MCQ days you get an exam-style question — syllogism, data sufficiency, coding-decoding, number series and more — and pick the one correct option. Every puzzle, whatever the format, 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.
