Terms of use

The game

Quasi is free entertainment for groups sharing one device. It requires no player account or payment and displays no advertisements. These terms cover that version of the game.

Answers and availability

Follow the definition, unit and rounding rule printed with each question. The initial question bank was written with AI assistance and has not been independently fact-checked; it does not yet include source references. Answers can be wrong and may need corrections. The game’s content is for entertainment and is not professional advice.

Features, questions and availability may change. Local saves and downloaded content can be lost if a browser clears data, storage fills up or software changes. Do not use the game as the only copy of information you need to keep.

Fair use

Use the game lawfully and considerately. Do not disrupt it, bypass technical restrictions, inject malicious code or use it to harass people. Player names should be appropriate for the group and should not expose another person’s private information.

Content and other people’s rights

The original wording, interface, artwork and other game assets may be protected by intellectual-property rights. Playing does not transfer ownership or give permission to redistribute protected assets. References to other people, brands or works do not imply their endorsement; third parties retain their own rights.

Responsibility and applicable law

Spanish law governs these terms. If you are a consumer, this choice does not take away mandatory protections under the law that applies where you habitually live. Your mandatory consumer rights and the courts available to you under applicable law remain unchanged. Nothing in these terms excludes liability that cannot lawfully be excluded.

Contact the operator below with questions, corrections or complaints. Changes to these terms will be published here.
