DEDUCTIONARY THE BOOK

A New Kind Of Puzzle Book

DEDUCTIONARY is a new kind of logic puzzle that turns reasoning into an art. Each puzzle challenges you to place 15 letters into a 5×5 grid, guided by 10 icon cells and a set of precise clues.

Every placement must be earned through logic — no guessing. Observe carefully. Cross-check clues. Deduce each step until the grid is complete. The result: one perfectly logical solution.

Includes 50 handcrafted puzzles and solutions in the back pages. A must-have for fans of Sudoku, logic grids, and brain-teasing challenges.

Think differently. Deduce precisely. Solve completely.
