Who we are

We're not a company or a big studio — just two people who make small, calm apps and websites together, and SkillSudoku is one of them. We build the sort of things we'd want to use ourselves: clean, uncluttered, and quick to load. No accounts, no paywalls, no endless interruptions — just a board, nine digits, and your own pace.

The two of us are Nadya Yashchuk and Ivan Lukichev, and we handle everything ourselves — design, development, puzzles, and support. We work remotely, and our apps are officially published as a small sole proprietorship registered in Austria; the formal details live in our Impressum. Because it's just the two of us, everything stays personal — we choose what to build, answer our own email, and shape each update around what players actually ask for.

What SkillSudoku does

The whole site is built around one idea: get you solving as fast as possible. The homepage opens straight onto a fresh board, and dedicated pages keep easy, medium, and hard puzzles one click away. The daily Sudoku gives everyone the same board each day, and the guide section explains the rules, common mistakes, and solving strategies in plain English — no filler, no jargon.

  • Play instantly: no sign-up, no downloads — the board is ready when the page loads.
  • Pick your pace: easy, medium, hard, and one shared daily puzzle.
  • Built for mobile: large number buttons and a grid that fits any screen.
  • Learn as you go: a full guide from first rules to real strategies.

Our other projects

SkillSudoku is part of a small family of free brain games we build and look after. If you enjoy logic puzzles, try Sudoku Play for daily boards from easy to expert, or Math Puzzles for quick mental-math challenges. Everything we make follows the same promise: simple, friendly, and free to play.

Say hello

We genuinely read what people send us, and a lot of what goes into the site comes from player suggestions. Questions, ideas, bug reports or just a kind word — reach us at contact@nadzeyayashchuk.com. For legal and company details, see our Impressum and Privacy Policy.
