Deduce Pro picks provably-correct puzzles on the exact reasoning types costing you marks — the puzzle book that rewrites itself to your weak spots, with the full worked solution every time. It covers all 28 reasoning types asked in IBPS, SBI and other exams — seating and floor arrangements plus MCQ formats like syllogisms, data sufficiency and coding-decoding.

How is Pro different from the Deduce Puzzle Book?

The Puzzle Book is a one-time purchase: 150 solver-validated puzzles, yours forever. Pro never runs out — it generates fresh puzzles daily, tunes them to the types you keep missing, and includes the Past Puzzles archive. Same engine, personalised and endless.

How much does Pro cost?

₹199 per month, auto-renewing via UPI Autopay or card. Cancel anytime from My Account — your current month keeps running to the end.

Deduce Pro — adaptive reasoning practice, ₹199 per month

Deduce Pro — solver-validated practice tuned to the marks you're losing

Endless fresh, solver-validated puzzles picked by what you keep getting wrong, with the full worked solution every time.

How it works

Every puzzle is proved before you see it. Our solver checks each generated puzzle has exactly one solution — no ambiguous questions, no answer-key debates, and nothing to memorise from a leaked PDF.
Coach watches what you miss. Linear seating, circular tables, double rows, floors, syllogisms — it tracks which types cost you marks and at what difficulty.
Your practice rewrites itself. Each session serves the types you're weakest at, at the level you're ready for — and every puzzle ends with the full step-by-step elimination, because the solver knows the reasoning, not just the answer.

A coach on each side

Your Pro membership unlocks both apps. If you haven't visited ComputePrep yet, it's our sister app for high-speed quant and vedic maths drills. Because you get both, you also get both AI coaches:

ComputePrep · quant

Ganak

Your quant coach on ComputePrep. After a drill he explains the fastest route — the vedic shortcut, where your method lost seconds. Everyone meets him on their first drill; Pro keeps him on every drill after that.

Deduce · reasoning

Saarathi

Your reasoning coach. Offers Socratic hints that diagnose exactly where your case-branching stalled — without giving away the full answer — and tracks which puzzle types cost you marks, so you know what to drill next. With Pro: 120 coach turns a day.

And on every page — free, for everyone — a second assistant, Asha, answers how-to, pricing and account questions.

Why aspirants trust it

A question bank can be crammed and an answer key can be wrong. Deduce puzzles are generated fresh and machine-verified to have exactly one solution, so the practice is honest: if you got it wrong, the walkthrough shows the exact chain of eliminations you missed. That is what moves your reasoning score — not re-reading questions you have already seen.
