The Deadly Deduction Files

Study the illustrated floor plan, read every clue, and place each character in the correct square. Like Sudoku, no two characters may share the same row or column. As the possibilities disappear, the completed scene reveals the only suspect who could be the murderer.

Every case is built around pure deductive reasoning and has one verified solution. No mathematics, random guessing, or outside knowledge is required—only careful reading, logical elimination, and a sharp detective’s eye.

Perfect for fans of Sudoku, logic grid puzzles, whodunits, cozy mysteries, detective games, and challenging brain teasers, these cases provide hours of focused, screen-free entertainment. The four difficulty levels make the collection approachable for new investigators while giving experienced puzzle solvers increasingly complex cases to crack.

Open the first file, follow every true statement, and eliminate the impossible. The scene holds the answer—but only deduction will expose the killer.
