About Sudoku Mansion

Sudoku Mansion is a story-driven puzzle adventure in which you explore a mysterious mansion and solve handcrafted Sudoku variants. As you uncover forgotten inventions, you investigate the disappearance of the mansion’s servants and a mystery hidden within its rooms.

Explore the mansion

The mansion is interconnected, with secret rooms and hidden vaults to discover. Some puzzles are tucked away for players who question what they have learned, and the greatest mysteries lie off the main path. You can also encounter traps and boss puzzles that test your mastery.

Solve the puzzles

The game contains over 50 handcrafted logic puzzles, with no randomly generated levels. Each room introduces exactly one new concept, gradually building from familiar Sudoku principles to more sophisticated mechanics.

As you explore, you unlock puzzle classes that change how you interpret familiar rooms. A puzzle solved as a German Whisperer may have a different solution when approached as a Region Sum Ambassador; its layout stays the same, while its rules and logic change. Revisiting earlier rooms with newly unlocked classes can reveal another perspective.

Uncover the story

An invitation brings you to the mansion, where a strange invention and references to missing servants and unstable rooms point to something beyond the puzzles. You piece together what happened to the vanished servants and investigate whether the invention is a salvation or a ruin.

Puzzle creator

Nurator, a puzzle setter known for Sudoku variants, created the puzzles in Sudoku Mansion. His puzzles have also appeared multiple times on Cracking the Cryptic.
