1. Acceptance of Terms

By accessing or using playversusai.com ("the Service"), you agree to be bound by these Terms of Service. If you do not agree to these terms, please do not use the Service.

These terms apply to all visitors, users, and anyone who accesses or uses the Service, including unregistered users who play games as guests. How we handle personal data is explained separately in our Privacy Policy and Cookie Policy.

2. A Free, Ad-Supported Service

All games on the Service are free to play. There are no purchases, subscriptions, in-game currencies or real-money prizes. Card games such as Blackjack use points for scoring only and involve no gambling of any kind. The Service is funded by advertising served by Google AdSense, as described in our Cookie Policy.

3. Account Registration

Some features, such as saved statistics, leaderboard placement and online multiplayer, require an account. When registering, you agree to the following:

  • You must provide a valid email address that you control during registration.
  • You must be at least 13 years of age to create an account, and if you are under the age of digital consent in your country you must have a parent or guardian's permission.
  • You are responsible for maintaining the security of your password and account credentials. If you forget your password, use the "Forgot password?" link on the login form to set a new one.
  • Each person may only maintain one account. Creating multiple accounts to manipulate leaderboards or circumvent bans is prohibited.
  • Your username must follow our community guidelines — offensive, discriminatory, or inappropriate usernames are not permitted and may be changed or result in account suspension.

4. Acceptable Use

You agree to use the Service fairly and respectfully. The following activities are strictly prohibited:

  • Using bots, scripts, automation tools, or any external software to play games or manipulate leaderboard rankings or high scores.
  • Exploiting bugs, glitches, or vulnerabilities in the games or platform. If you discover a bug, please report it to us.
  • Harassing, threatening, or engaging in abusive behavior toward other users, including opponents in online multiplayer matches.
  • Impersonating other users, staff members, or any other individual or entity.
  • Attempting to gain unauthorized access to other users' accounts or the Service's infrastructure.

5. Game Data and Replays

Finished games on PlayVersusAI are recorded, including the move history, result, difficulty, duration and scores. By using the Service, you acknowledge and agree that:

  • Game records are stored in our database, which is operated by our provider Supabase.
  • Finished games appear in the public recent-games feed and can be replayed move by move by anyone. Games played while signed in show your username; guest games are shown as Anonymous.
  • Game results, including wins, losses, draws, high scores and fastest times, appear on public leaderboards alongside your username when you are signed in.
  • We may use game data to run the site, compute site-wide statistics, fix bugs, and improve our games and AI opponents.

6. Intellectual Property

The rules of the classic games offered here are in the public domain. Our implementations of them, including the website design, game code, AI engines, graphics, logos, guides and articles, belong to PlayVersusAI and are protected by applicable intellectual property laws. You may not copy, redistribute or create derivative works from them without our prior written permission, although you are welcome to link to any page and to share screenshots of your own games.

7. Improving the AI Opponents

The AI opponents run in your browser and do not adapt to individual players during play. We may use game records, and anonymous position statistics recorded when signed-in players win certain games with Coach Mode on, to analyse and tune future versions of the engines. Position statistics are stored without any user ID or username. See the Privacy Policy for details.

8. Account Suspension and Deletion

We reserve the right to suspend, restrict, or permanently ban any account at our sole discretion, including but not limited to the following reasons:

  • Violation of any provision of these Terms of Service.
  • Detection of suspicious activity, including bot usage or automated play patterns.
  • Abusive, harassing, or disruptive behavior toward other users or the platform.
  • Creating multiple accounts to evade a previous suspension or ban.

Suspended or banned users may lose access to their game history, leaderboard rankings, and all other account data.

You may stop using the Service at any time. To delete your account and the data linked to it, email admin@playversusai.com from the address registered to the account, as described in the Privacy Policy.

9. Third-Party Services and Advertising

The Service relies on third parties, including Supabase for accounts and data and Google for advertising and consent management. Ads are provided by Google and its partners; we do not control or endorse the products advertised, and your dealings with advertisers are solely between you and them.

10. Disclaimer of Warranties

The Service is provided on an "as is" and "as available" basis, without warranties of any kind, either express or implied, including but not limited to implied warranties of merchantability, fitness for a particular purpose, or non-infringement.

We do not guarantee that the Service will be uninterrupted, error-free, secure, or available at any particular time. We reserve the right to modify, suspend, or discontinue the Service at any time without prior notice.

11. Limitation of Liability

To the fullest extent permitted by applicable law, PlayVersusAI and its operators shall not be liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of profits, data, use, or goodwill, arising out of or in connection with your use of the Service.

This limitation applies regardless of the legal theory on which the claim is based, including negligence, breach of contract, or any other legal theory, even if we have been advised of the possibility of such damages.

12. Changes to Terms

We reserve the right to modify or replace these Terms of Service at any time at our sole discretion. When changes are made, we will update the date at the top of this page.

Your continued use of the Service after any changes to these terms constitutes your acceptance of the revised terms. We encourage you to review this page periodically to stay informed of any updates.
