Practise bank-exam reasoning offline
Deduce is an installable app (a PWA) — add it to your phone's home screen with no Play Store or App Store. It opens instantly even on a dead signal, and the daily puzzle needs only a few seconds of connection (a few KB — 2G is enough) to load and submit, because every puzzle is generated, timed and checked on the server — that's what keeps the leaderboard fair. For truly zero-signal practice, grab the free 20-puzzle PDF sample. It's free to play, for IBPS, SBI and SSC prep.

How to install
- Android / Chrome: open deducepuzzles.com, then menu → Install app (or tap the "Install" prompt).
- iPhone / Safari: open the site, tap Share → Add to Home Screen.
It installs in seconds, takes almost no storage, updates itself, and opens full-screen like a native app.
Why this matters for prep
- Practise in the gaps. The commute, the queue, the load-shedding hour — that's where a five-minute daily rep actually fits, and a flaky 2G bar is enough to fetch and submit the day's puzzle.
- Zero-signal backup. Keep the free 20-puzzle PDF sample (or the full 150-puzzle book) on your phone for the stretches with no network at all — same solver-validated puzzles, full worked solutions.
- Daily reminders. Turn on a 7pm nudge so today's puzzle never slips — one of the ways Deduce is built for a daily habit, not a cram session.
Same validated puzzle, wherever you are
App or PDF, every puzzle is machine-checked to have exactly one solution before it's served, with a full worked solution after each round. See everything Deduce does on the features page, learn the rules in the how-to-play guide, or read the FAQ.
