Terms of Service
Last updated 4 August 2026
Ascendoku is a free sudoku game run as a personal, non-commercial project from Finland. By playing it you accept these terms. They are deliberately short.
Your account
You can play most of the game without an account. If you create one, keep it to yourself — one account per person, and you are responsible for what happens under it. Choose a display name that you would be happy to see on a public leaderboard; we may change or remove names that are offensive or that impersonate someone else.
Fair play
Solve the puzzles yourself. Do not use solvers, scripts or automated tools to post times or climb the leaderboards, and do not try to submit results the game did not produce. We may reset scores, remove leaderboard entries or close accounts that do this. Beyond that: no attacking or overloading the service, and no attempting to reach other players' data.
Availability
The game is provided as it is, for free, with no guarantee that it will work, stay available, or keep your data. It runs on free hosting tiers, and there are no backups — progress can be lost, and features can change or disappear. Please enjoy it as a game rather than relying on it for anything important.
Puzzles and content
The puzzles, artwork and code are ours. You are welcome to play them, share links, and post screenshots or videos of your solves. Please do not scrape the puzzle library or redistribute it as your own.
Ending it
You can stop playing at any time and delete your account from your Profile — see the Privacy Policy. We may suspend or close accounts that break these terms, and we may discontinue the service altogether if it stops being viable to run.
Liability
To the extent the law allows, we are not liable for any loss arising from using — or being unable to use — a free puzzle game. Nothing here limits rights you have as a consumer that cannot be limited.
Law
These terms are governed by Finnish law.
Changes
We may update these terms. The date at the top will change, and significant changes will be announced in the app.
