4 September 2026. These terms cover Twenty or One, a game made by one person. They are written in plain language rather than legal language. Nobody involved in writing them is a lawyer, and they are not legal advice — they describe how the game works and what we ask of you.
Twenty or One is free. There is no account, nothing to buy, and no advertising. You may play it, share links to it, and stop using it at any time.
Choose a display name you would be happy for another player to see, and don’t use it to harass, impersonate, or abuse anyone. Names pass through an automated filter, but a filter is not judgement — if someone’s name or conduct is a problem, use the report or block controls in the game.
Reporting a player tells us which player you mean and why, so we can review it. Blocking a player ends play between the two of you in both directions. We review reports and act on them within a few days. Deleting your data removes every block and report connected to your device, in both directions.
It is under active development: rules, scoring and features may change, and a rating is a number in this game and nothing more.
The game is provided as it is. We do our best to keep it working and your data safe, but we can’t promise it will always be available or error-free.
How we handle data is covered by the Privacy Policy, which is the authority on that subject. Where these terms and that policy touch, the policy governs.
These terms are governed by the laws of Ontario, Canada.
