Why it's free
Every game here is free, and no game feature is locked behind payment. Server and domain costs are covered by Google AdSense ads (ad slots may appear empty until approval). There is nothing to buy; everyone gets the same games and features.
Even with ads, we draw a clear line: no ads on the gameplay screen. No ads on the board, between rounds, or at the moment you see the answer. Ads only appear on home, results, and guide screens — where your hands are already at rest.
We do not sell personal information for revenue. We don't collect names or emails in the first place, so there's nothing to sell. What we collect and what we don't is detailed in our Privacy Policy, broken down by game.
Principles we follow
- No login required — you shouldn't need an account to start playing.
- Don't collect what you don't need — a nickname for the leaderboard is enough.
- Mobile first — must work comfortably at 320px width without horizontal scroll.
- Dark mode and accessibility from day one — keyboard controls, contrast, reduced motion built in.
- Keep it light — it should start the moment you open it.
How we build it
- The operator decides what gets built and when it is released. AI development tools are used for writing code and drafting guide text, and every release goes through automated tests and an on-screen check before it is published.
- The core rules of each game (Sudoku solution uniqueness, 2048 tile merging, mine placement and the safe first click, Hangul letter assembly, block rotation and line clears, typing-speed calculation) are pinned down by automated tests that run again on every change.
- Every Sudoku grid is checked by a solver to have exactly one answer, and No-Guess Weekly boards are checked to be solvable without guessing before release. The typing-speed formula and its test set are published on the measurement page.
- Guides and explainers are checked against the game code so that nothing describes behaviour the game does not have, and each one shows who wrote and reviewed it and when it was last updated.
Update policy
- Daily puzzles (Sudoku, 2048, Minesweeper, Word and BlockDrop dailies, plus the typing sentence of the day) change automatically at midnight Korea time. The No-Guess Weekly opens a new board every week.
- When rules or controls change, the guides for that game are corrected in the same release and their update date is refreshed.
- Reported bugs are fixed once they can be reproduced, and factual errors in explanations are corrected ahead of other work.
- When the privacy policy changes, the effective date and revision history are recorded on the policy page.
How to contact us
All enquiries go to a single email address. For bug reports, please include the game name, your device and browser, and what you did right before the problem appeared; it makes reproducing and fixing it much faster. Leaderboard record deletion requests go to the same address.
