Make the section everyone fears your strongest.
Reasoning decides a huge share of your marks, and most aspirants lose them to the clock, not the logic. Deduce gives you three exam-grade puzzles a day — Easy, Medium and Hard — each machine-proven to have exactly one answer, so the key is never wrong.
No account needed to play. Free forever — today's puzzles always are.

Questions
Is it really free?
Yes. Today's puzzle is free forever, at all three levels, and you can solve it without making an account. Pro adds the Saarathi coach, unlimited practice and the full archive.
What does "solver-verified" mean?
Every puzzle is checked by the engine before it is served, and no puzzle ships unless it has been proven to have exactly one solution. So the answer key is never wrong and you are never learning a method that only works by luck.
Which exams is this for?
Banking (IBPS, SBI, RBI), SSC, RRB, UPSC and State PSC — and the reasoning also maps onto GMAT data sufficiency and deductive logic. You pick your exam and the daily tunes its topic mix to it.
Do I need to install anything?
No. It runs in your browser and installs as an app if you want it to. Start on your phone in a few seconds.
Why should I sign in?
So your streak, times and progress survive a cleared cache or a new phone — and so we can send you the daily nudge. You can sign in with Google or with an email code; no password to remember either way.
