Sudoku Mansion

Sudoku Mansion is a story-driven puzzle adventure where you explore a mysterious mansion and solve increasingly challenging Sudoku puzzles.
From the Puzzle Creator Nurator
Sudoku Mansion is created by Nurator, a puzzle setter known for his Sudoku variants.
Nurator's puzzles have been featured multiple times on Cracking the Cryptic, one of the world's best-known Sudoku and logic puzzle channels. Check out the Youtube Link on the right side for an example.
If you've encountered Nurator's puzzles before, you'll find that same love of unusual logic and elegant mechanics throughout the mansion.
Enter Sudoku Mansion
The invitation arrives without warning.
No name, no seal.
Only rushed references to missing servants, unstable rooms and a strange invention.
Two sentences have been underlined twice:
"I have found a way to reach beyond the grid. I no longer know whether that is our salvation or our ruin."
Step inside a mysterious mansion where every room is a handcrafted Sudoku variant. Uncover forgotten inventions as you unravel a mystery hidden deep inside the mansion.

Every Room Teaches Something New
Sudoku Mansion is built around one simple idea:
Every room introduces exactly one new concept.
What begins with familiar Sudoku principles gradually evolves into increasingly sophisticated puzzles. New mechanics are introduced one at a time, allowing every discovery to feel earned while constantly expanding the possibilities.
Every puzzle has been handcrafted. There are no randomly generated levels.

Built for Comfortable Play
Logic should be the challenge, not the interface.
Sudoku Mansion includes a variety of accessibility options to help you focus on solving puzzles your way. Adjust text sizes for comfortable reading, choose alternative color themes, enable colorblind-friendly visuals and customize the appearance of puzzle elements to suit your preferences.
The game is fully playable with only a mouse or only a keyboard and you can freely rebind all hotkeys in the game.
Whether you're settling in for a quick puzzle or an evening of exploration, the mansion is designed to be comfortable to play in.

Knowledge Changes the Mansion
As you explore, you'll unlock powerful puzzle classes that completely change how you interpret familiar rooms.
A puzzle once solved as a German Whisperer may later reveal an entirely different solution as a Region Sum Ambassador. The layout remains unchanged. But the rules and the logic transform completely.
And those are only two of the disciplines waiting to be discovered.
Each new class unlocks another perspective, rewarding players who revisit earlier rooms with fresh eyes.

Secrets Hide Behind Every Door
The mansion rewards curiosity.
Closed Vaults.
Traps you better be very careful around.
Some puzzles exist only for those willing to question what they've already learned.
The greatest mysteries are never placed on the main path.

A Mystery Beyond the Grid
The mansions servants have vanished.
Piece together what actually happened as you uncover the truth behind Sudoku Mansion.
