Dupery: A Game of Solo Deduction (v1.0.3)

A rain-slick noir city becomes a logic puzzle where every witness may be manipulating the truth. Dupery: A Game of Solo Deduction casts you as a detective working through a syndicate-infested metropolis, identifying criminals hidden among civilians, opportunists, and far more dangerous conspirators. Its tension comes less from action than from uncertainty: a convincing statement can be a vital lead, a deliberate lie, or technically true information designed to send you after the wrong suspect. The mood is methodical and paranoid, rewarding players who enjoy taking notes, testing theories, and distrusting easy answers.

Each procedurally assembled case places a collection of roles on a grid and asks you to determine every evil character before making arrests. You interrogate suspects, compare their clues, and use an in-game board with strings, pins, and written notes to map connections between statements and positions. More than 175 handcrafted roles create the puzzle vocabulary, with effects ranging from mathematical information about villain locations to hazards that multiply the penalty for an incorrect accusation. Reputation acts as the run’s health bar: correctly clearing a case raises your standing, while arresting innocent people can end your career. Between missions, you choose roles, quirks, and modifiers that shape the cases ahead, giving the deduction loop a roguelite layer beyond simply solving isolated mysteries.

Three regional campaigns introduce their own mechanics and role sets, culminating in confrontations with local syndicate generals who reveal pieces of the wider conspiracy. Unlocking higher role tiers steadily expands the range of possible deceptions, so later investigations demand a stronger grasp of how information can conflict, overlap, or conceal intent. The final syndicate run draws on everything learned across the regions, making it feel like a genuine exam rather than a standard boss fight. Fans of logic-grid puzzles, social-deduction games such as Town of Salem, and roguelites built around knowledge rather than reflexes should find plenty to dig into, though players who dislike ambiguity or punishment for bad calls may find its suspicion-heavy design demanding.
