Puzzles by Dr Djape: 300 puzzles

Puzzles by Dr Djape - 300 Sudoku Variants from an Author Who Earned His Title

This is the first book DJAPE signed as "Dr Djape" - published exactly one year after defending his PhD thesis in Computer Science. It is also one of his most personal and ambitious collections.

300 puzzles spanning a wide variety of Sudoku variant types, curated for experienced puzzlers. This is not a beginner book. DJAPE assumes you know how standard Sudoku works and jumps straight into the variants - overlapping grids, exotic constraints, combined rules, and formats that challenge even solvers who think they have seen everything.

The book reflects two decades of puzzle-making expertise, combining the mathematical precision of a computer scientist with the creative playfulness of someone who genuinely loves inventing new puzzle types. If you want to see what happens when a puzzle maker with a doctorate designs his signature collection, this is it.

300 puzzles. 7 x 10 inch format. All rules explained. All solutions included. From Dr DJAPE - Washington Post Samurai Sudoku author since 2006, over 250 published books.
