Coach — 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

  1. 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.
  2. Coach watches what you miss. Linear seating, circular tables, double rows, floors, syllogisms — it tracks which types cost you marks and at what difficulty.
  3. 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.

Meet Saarathi — your AI reasoning coach

Coach isn't just more puzzles — it comes with Saarathi, an AI tutor built into Practice. Ask "why is that the answer?" and it walks the deduction step by step; it reads which reasoning types you keep missing and tells you exactly what to drill next, one tap away; and after a round it spots how you slipped and gives a technique tip for that type. It's grounded in Deduce and never invents a puzzle — it only picks from the validated set. More on the AI coach →

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.
