Play today's puzzle →The daily challenge FREE
One quality rep a day — the core habit.
- A fresh daily puzzle at all three levels. Easy, Medium and Hard every day (of the same reasoning type), each with its own timer and leaderboard — clear one or all three.
- Three attempts, and it tells you what you got wrong. On a wrong arrangement you're told how many clues you violated; MCQ days are one attempt, like the real exam.
- Streaks. A day counts the moment you win any difficulty — a tiny, winnable daily goal that keeps the habit alive.
- A free first-win warm-up. New players get a 60-second validated MCQ with a full walkthrough, so your very first day ends in a win, not a blank board.
- Shareable result. Post your result to WhatsApp, Telegram or anywhere — spoiler-free, like the games you already share.
27 reasoning types FREE
Real exam variety, rotating daily — not the same puzzle every day.
8 arrangement types (solved on an interactive board): Floor / building arrangement, Circular seating, Square seating, Row seating, Double-row (two rows facing each other), Order & Ranking, Scheduling (day-of-week), and Box arrangement.
19 multiple-choice types (pick one, like the exam): Data Sufficiency (floor and ranking), Coding-Decoding, Message Coding, Syllogisms, Blood Relations (plus coded and photo variants), Coded Inequality, Number Series, Number and Letter Classification, Alphabet Test, Alphanumeric Series, Machine Input-Output, Direction & Distance, Uncertain Persons, Eligibility Test, and derived Seating-Arrangement MCQs.
The daily type rotates by date, so board days and MCQ days are spread out — every kind matches a high-frequency banking/SSC reasoning topic. See one real example of all 27 types →
Why you can trust every puzzle
The thing a PDF or a question bank cannot promise.
- Exactly one solution, proven. FREE Every puzzle is machine-checked to have one and only one answer before it's served — so there's always a clean logical path and never an unfair guess.
- Server-timed, server-scored. FREE Your clock, attempts and score are computed on the server, not your device — the leaderboard reflects real solving and can't be gamed.
- Full worked solution, every round. FREE Win or lose, you get the step-by-step deduction — the part that actually builds skill.
- Fresh and un-crammable. FREE Puzzles are generated, not pulled from a fixed set, so you can't memorise your way through them.
Coaching that finds your weak spots
Turn the daily rep into targeted improvement.
- My Progress. FREE Your per-type win-rate, solve speed and weakest/strongest reasoning types — so you know exactly what to drill.
- Ask Shakthi. FREE A built-in AI assistant on every page that answers "how do I play?", "what's a streak freeze?", pricing and account questions — grounded in Deduce, so no made-up answers.
- Descriptive hints. FREE One free hint a day reveals a placement and the clue that proves it — it teaches the step, not just the answer (three a day on Coach).
- Adaptive Practice. COACH A separate, endless practice track that reads your skill rating and serves more of the types you're weakest at — targeted reps, not random ones.
- Saarathi, your reasoning coach. COACH The AI coach inside Practice: it recommends the exact type and level to drill next, and explains the why behind a solution — one tap loads the puzzle it suggests.
- Post-solve coaching tips. COACH After a practice round it spots how you slipped (rushed, hint-reliant, concept gap) and gives a technique tip for that exact reasoning type.
- Past Puzzles archive. COACH Re-attempt any previous day's puzzle across all 27 types, with the full walkthrough — perfect for exam-week revision.
Stay in the habit
