NUMERICAL ALCHEMIST

Beyond Sudoku, a new kind of logic puzzle experience.

\

Numerical Alchemist is a number-placement logic puzzle built on a 9x9 Sudoku grid and advanced through eight original constraints. Alongside the standard Sudoku rules for rows, columns, and 3x3 blocks, multiple conditions shape the board at once, including adjacent sums, greater-than and less-than relationships, parity matching, multiple and divisor relationships, and local area structures. Success comes not from guesswork or brute force, but from the observation and deduction needed to find the one point where constraints intersect.

\

Every stage is designed to be solved without assumptions. Rather than testing "what if this is 1?", you work only from the information already on the board and reach the answer through pure logic. A puzzle that first looks impenetrable can begin to unravel in a chain reaction after a single discovery. Even experienced Sudoku players can find a fresh perspective and a satisfying mental challenge here.

As an alchemist reading the truths hidden in numbers, you challenge boards inscribed with numerical laws. By clearing stages prepared across multiple chapters, you move into puzzles with increasingly complex structures. The game aims for a quiet, thoughtful atmosphere, with minimalist, immersive play in which every move matters.

\

There are eight original constraints in the game. Each one works on its own, but when several overlap they create distinctive lines of reasoning across the board. The heart of the game is building a completely different solving feel on top of classic Sudoku. The more you understand what each constraint means, the more information you begin to see, and the more likely a once-opaque puzzle is to suddenly open up.

In story mode, you can challenge stages arranged by difficulty. As you progress, you earn titles and achievement records that show how far your logic has sharpened. Core support features including pencil marks, undo and redo, input aids, and error checking help you stay focused on thinking. Controls and readability are tuned so you can concentrate on complex boards.

\

The game also supports creating and sharing custom puzzles. You can freely place original constraints and design puzzles of your own. You can publish what you create for other players to challenge, or take on difficult puzzles made by the community. The game is built to last not only through solving, but also through creating and sharing.

For anyone who wants more than standard Sudoku. For anyone who wants the pleasure of opening a board through logic alone. This is not simply a game about filling in numbers, but about extracting truth from overlapping constraints.
