About attention and reaction challenges
For a clear understanding of the site: 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. Refer to the game page for its available format.
Third-party information and services
Please note this distinction. 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. Read a destination’s own information before using it.
Available rounds and stored card games
Before relying on a result or explanation, remember: 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. Results should be understood in the context of the game.
Read the stated format
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. Check the relevant rule before drawing a conclusion.
Performance varies with your setup
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. Check the relevant rule before drawing a conclusion.
Understanding our independent status
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. The contact form is available for questions.
Using examples without a qualification claim
For a clear understanding of the site: 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. Refer to the game page for its available format.
Questions about inaccurate information
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. A score does not replace professional advice.
Enjoyment rather than real-money play
For a clear understanding of the site: 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. Use a clear example when reporting an error.
Site access and device-based progress
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. Check the relevant rule before drawing a conclusion.
