About variations in game rules
Keep this limit in mind when playing. 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. Use a clear example when reporting an error.
What practice results do not certify
Keep this limit in mind when playing. 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. Take a break when a round stops being enjoyable.
Understanding external destinations
Keep this limit in mind when playing. 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 the description for the activity you choose.
Availability of play and stored progress
Before relying on a result or explanation, remember: 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. Read the description for the activity you choose.
About the independence of this site
Keep this limit in mind when playing. 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. A score does not replace professional advice.
Available rounds and stored card games
Keep this limit in mind when playing. 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. Read the description for the activity you choose.
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.
Reporting issues in games or instructions
For a clear understanding of the site: 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. The contact form is available for questions.
Play as a recreational activity
Keep this limit in mind when playing. 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.
Browser performance and your experience
Before relying on a result or explanation, remember: 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. Read a destination’s own information before using it.
