What is Pistari?
A relational puzzle where you deduce who did what, where, when — using only clues and logic.
Each puzzle has a relational grid: rows are real historical figures (Einstein, Marie Curie, Tesla, Newton). Columns are attributes to deduce (country, era, discovery, instrument — whatever fits the theme).
Clues are sentences that combine formal logic with cultural references: a subtle mention of an era, a feature of an instrument, a fact about an art movement. Some are direct ("Curie was born in Poland"), some eliminate ("Faraday isn't Italian"), some chain together ("Tesla was born between Newton and Einstein").
It's not just pure reasoning: you learn something with every puzzle. When you solve it, you discover a curious fact about one of the figures. That's what makes it different from traditional logic puzzles.
How to play
4 steps. The mechanic takes 2 minutes to learn; mastering it, years.
Pick a theme
Art, science, cinema, sports, gastronomy, history, literature, music or geography. Each theme has its own path of puzzles across multiple difficulties.
Read the clues
Each puzzle comes with a handful of clues — more as the grid grows. They can affirm ("Curie was born in Poland"), deny ("Newton wasn't Italian") or chain dates and relations.
Mark the grid
Tap a cell to mark ✓ (confirmed relation) or ✕ (eliminated). Every ✓ tidies its row and column: what you already deduced stays in view.
Solve and discover
When the grid is complete, tap Verify ◆: if everything is right, the case closes, you score points and a curious fact about one of the figures appears. If there are errors, it tells you how many (not which) — and every check with errors costs points, so think first.

Frequently asked questions
What people ask before downloading.
01 Is it free?
Yes — there's a free daily puzzle for everyone, rotating through the 9 themes each day. The full tutorial is also free. To unlock the full puzzle bank, you can buy a single theme pack or full access. No subscriptions.
02 How does the grid work?
Each puzzle is a relational grid where you deduce which figure matches which attributes using the clues. The size grows with difficulty: Easy is 4 figures and 2 categories; Hard goes up to 5 figures and 3 categories — wide enough that it plays in landscape.
03 Does it work offline?
Yes. Once you're in the app, you can play offline. The connection is only used to sync your progress to the cloud and to participate in the leaderboard if you choose to.
04 Do I need to create an account?
No. You start playing immediately with an automatic anonymous account. If you want, you can link an email so your progress follows you when you switch phones. Your call.
05 How do you earn points?
Every solved puzzle scores by difficulty: 100 on Easy, 200 on Medium, 350 on Hard. Each check with errors costs 15 and each hint costs 8 — a clean solve earns the Flawless case seal. And every 8 puzzles completed on a path unlocks a milestone: +500 points and +5 hints. Points feed the leaderboard (weekly, monthly and all-time, global and by country).
06 And what about hints?
Hints (💡) reveal one correct cell. You start with 3, earn 5 with every milestone, and get 20 bonus hints with each theme pack (60 with Full Access). If you run out, you can buy more in packs of 10, 20 or 50. Each hint used costs 8 points on that puzzle.
