Why this variety matters
Bank and SSC reasoning sections don't repeat one puzzle type — prelims mix seating, ranking, coding, series, syllogisms and data sufficiency in a single hour. Practising one format on repeat builds a skill the paper never tests alone. Deduce's daily rotates the full set by date (weighted to your exam's mix), so over a month you touch every family — and Saarathi, the AI coach, spots which of the 27 you keep missing and tells you which to drill next.
Every type above runs on the same server-validated engine: freshly generated (never from a question bank), timed on the server, and always with a full worked solution at the end. See everything Deduce does →
