What's inside the free 20

Two puzzles from each of ten families: linear seating, circular seating, floor arrangement, box & square arrangement, scheduling, order & ranking, syllogism, coded inequality, blood relations, and coding-decoding & classification. Mixed difficulty, with the worked answer key at the back.

Then pick the book for your exam

Each edition is 100 puzzles drawn from the same validated pool, weighted to that exam's own topic mix. No question type is exclusive to one edition — the weighting is what differs, and it is what makes an hour of practice match your paper.

All paid books below are the 2026 edition. Editions are cut each December and go live on 1 January.

Banking Edition

IBPS PO · SBI Clerk · RBI Grade B

Seating-heavy, the way banking papers are: floor, circular, linear and double-row arrangement lead, then syllogism, coded inequality, ranking and blood relations.

₹299

SSC Edition

SSC CGL · CHSL · CPO

Leads with coding-decoding and classification — the two SSC leans on hardest — then blood relations, ranking, floor arrangement, inequality and syllogism.

₹299

Railway (RRB) Edition

RRB NTPC · Group D · ALP

The flattest mix of the six, matching RRB's spread: coding, classification, syllogism and inequality all carry weight alongside blood relations, ranking and seating.

₹299

UPSC CSAT Edition

UPSC CSAT Paper II

Built for CSAT's logic half: syllogism and coded inequality lead, followed by data sufficiency, ranking, arrangement and classification.

₹299

State PSC Edition

State PSC prelims

An even eight-way spread — syllogism, inequality, classification, coding, blood relations, ranking, floor arrangement and data sufficiency — because state papers vary.

₹299

GRE / GMAT Edition

GRE & GMAT — data sufficiency and deductive logic

Sufficiency judgement first: data sufficiency leads, then coded inequality and syllogism, with ranking, classification and blood relations behind them.

Questions

Is the PDF really free?

Yes — it downloads on tap, with no sign-up, no email and no payment. Leaving a contact afterwards is optional and only adds the daily nudge. Forward the file to whoever you like.

How do you know every puzzle has one answer?

Each puzzle is generated and then handed to a constraint solver, which enumerates the solutions. A puzzle with two valid answers — or none — is discarded and never reaches a book. It is the same check that runs on the daily puzzle before it is served.

What is the difference between an edition and the full book?

The full book is 150 puzzles across all 28 reasoning types. An edition is 100 puzzles drawn from the same pool but weighted to one exam's topic mix. If you sit one exam, the edition wastes less of your time; if you sit several, the full book covers more ground.

How is the book delivered?

As a PDF, by email, immediately after payment — there is nothing physical to ship. Payment is by UPI, card, netbanking or wallet through Razorpay. See our refund policy before buying.
