Each puzzle is a heist. Each heist advances the story. As you solve logic grids — determining who stole what, where, and how — you piece together the narrative of an unraveling conspiracy. The puzzles grow harder. The betrayals grow deeper. By the final grid, you'll know who the traitor is. If you're good enough.
If you've ever solved a logic puzzle — "the man in the red hat lives next to the baker" — you know the format. Now imagine 80 of them woven into a story.
Each puzzle opens with a scene: a city, a target, a set of suspects. The clues are embedded in the narrative.
Use deduction to fill the logic grid. Eliminate impossibilities. Connect facts. Find the only solution that fits.
Each solved puzzle reveals a piece of the conspiracy. The heists connect. The betrayal pattern emerges. The traitor has a name.
From 3×3 warm-ups to fiendish 5×5 grids with layered constraints.
Each with a specialty, a backstory, and a motive. One of them is the traitor.
Paris, Vienna, Istanbul, London, Monte Carlo. Each city is a chapter. Each chapter escalates.
Not just standalone puzzles. A real story that rewards you for solving every grid.
Every puzzle comes with a pre-printed logic grid. No need to draw your own.
Complete solutions at the back. With explanations so you can learn the logic, not just check the answer.
80 logic grid puzzles. 11 suspects. A conspiracy that unravels one deduction at a time. The only way to find the traitor is to solve every heist.
