Terms of service

Effective October 3, 2026

By using A2B, you agree to these terms. A2B is a daily logic puzzle provided for personal, non-commercial entertainment.

Using A2B

You may play the puzzles and use the site's features for their intended purpose. Do not attempt to disrupt the service, interfere with other users, or access systems or data that are not made available to you.

Puzzles and availability

A2B aims to publish puzzles that pass its verification process. The site is provided as available; uninterrupted access is not guaranteed. Features may change as A2B develops.

Accounts

Account sign-in is optional and is not required to play. If you choose to use an account feature when it becomes available, you are responsible for keeping access to your account secure. A2B may suspend access when needed to protect the service or address misuse.

Changes and contact

These terms may be updated as the service changes. The effective date above will be revised when that happens. Questions can be sent to neo.oscco@gmail.com.
