Bringing an issue to our attention
Before relying on a result or explanation, remember: An explanation or game may contain an error despite checks. Use the contact form to describe a suspected issue and the page where it occurs. A specific example helps distinguish an error from a different rule variant. Keep the purpose of the activity in mind.
Available rounds and stored card games
For a clear understanding of the site: Some activities reuse a fixed collection of puzzles or levels. A new round does not necessarily provide a board you have never seen. The game’s description gives the relevant collection or format details. Refer to the game page for its available format.
Understanding service and save limits
Access may be interrupted, and local saved progress may be lost when browser storage is removed. Keep these limits in mind when beginning a long round. There is no promise of uninterrupted access or cloud recovery of local records. Keep the purpose of the activity in mind.
Play as a recreational activity
Please note this distinction. Scores, puzzle results and practice rounds are for recreation. They are not earnings, investments or redeemable rewards. There are no cash stakes or prize withdrawals in these games. The contact form is available for questions.
Activities are not medical assessments
Please note this distinction. Card exercises support informal practice, not medical assessment or professional certification. A score records answers in one session, not an assessment of health or aptitude. Read a destination’s own information before using it.
How your device can affect play
For a clear understanding of the site: Animations and timing can be affected by device speed, browser behaviour and background activity. Scores from different devices may not be directly comparable. Close unrelated busy tabs when a timing-sensitive game feels uneven. A score does not replace professional advice.
Linked pages and their information
An external link does not guarantee the accuracy, safety or availability of its destination. Other services publish their own terms and information. Check the destination before sharing personal information or relying on a claim. Check the relevant rule before drawing a conclusion.
Rules can differ between versions
Please note this distinction. The Guide describes the format available here, including any small board, limited stage set or house rule. Other versions of a game may work differently. Judge a move against the rules displayed for that activity. Keep the purpose of the activity in mind.
The site and third-party names
For a clear understanding of the site: The site is an independent collection of browser card games and explanations. It is not an official Yono app or an account-support service for another publisher. A familiar game name does not make this an official brand service. Read a destination’s own information before using it.
Using examples without a qualification claim
Before relying on a result or explanation, remember: A score in a card-rules exercise is not an educational certificate or a professional assessment. Use the explanations as practice material. Different activities may measure different parts of the task. Use a clear example when reporting an error.
