Dedukto

Dedukto is a logic-grid deduction puzzle — the classic genre turned into a noir thriller. Every case is a file to crack in a dark room, under a single lamp: you light up the truth by stringing red thread between clues, not by guessing.

HOW IT WORKS
You're given a set of categories — people, objects, places — and must uncover the one combination that links them all. Mark each grid cell ✓ or ✗ by following the written clues and the logical deductions they unlock. Every puzzle is generated on the spot and guaranteed: solvable by pure logic (never by trial and error), with exactly one solution, and every clue genuinely necessary.

WHAT MAKES IT DIFFERENT
• No hand-written puzzles — a generator verifies every case is correct, unique, and fair before you ever see it.
• Real difficulty curve: from Tutorial to Expert, clues get progressively more indirect — relational, ordinal, distance-based, disjunctive.
• Cinematic noir look: breathing light, dust drifting through the lamp's glow, a red thread that physically snaps taut with every deduction.
• No noise: no ads, nothing to buy, fully playable offline.

GAME MODES
• Classic — the standard pace, with a timer and star rating per case.
• Time Attack — chase your own best times, saved locally per difficulty.
• Zen — no timer, no scoring: just you and the case, no pressure.
• No Mistakes — a single slip ends the run. For players who want the real hardcore challenge.
• Local Co-op (experimental) — two players, one device, each holding half the clues: solve it by talking it through together.

CONTENT & PROGRESSION
• Three themed packs: Classic, Investigation (suspects, weapons, motives — the murder-mystery skin) and Nature. Investigation also includes a short connected mini-campaign.
• Daily Puzzle — a new case every day, the same for everyone, with a daily streak to keep alive.
• Offline achievements and packs that unlock as you clear more cases.
• Graduated hints when you're stuck: an unused clue worth revisiting, one certain cell, or the mistake that's blocking you — never the full answer.
• Replay the solution after winning, step by step, to see exactly the reasoning you missed.

Light or dark theme, optional ambient audio, three complete languages (Italian, English, Spanish) — covering puzzle content and names, not just menus.

Dedukto doesn't have "levels" in the usual sense — it has an engine that generates endless, honest cases. Your only opponent is logic itself.
