About.

Variant sudoku has grown far beyond the 9×9 grid most people picture. Thermos, killer cages, German whispers, renban, kropki, arrow constraints, fog of war — there are dozens of constraint types now, and the community building puzzles around them is bigger than it's ever been.

But the tools didn't keep up. Setters publish on one site. Tests happen in Discord threads. Solvers track their progress in spreadsheets. Ratings live in YouTube comments. None of it talks to anything else.

Sudorix is the place that does the whole thing — every variant, every step from "I have an idea" to "the world solved my puzzle." One platform.

Built complete, not iterated into existence. We're not shipping a minimum viable product and waiting for complaints. The full vision is the launch.

Privacy is the product. We ask for your email — that's it. No tracking, no marketing email, no behavioral profiling. The promise lives at /privacy and isn't going anywhere.

Variants are first-class. Standard 9×9 is one of many. The renderer, importer, and editor all treat the full constraint zoo as the default case. No second tier for puzzle types that aren't classic.

Independent. Not VC-backed, not chasing engagement metrics. The plan is to make something good and charge a fair price for the bits worth paying for.
