The purpose of these activities
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. Keep the purpose of the activity in mind.
What to expect from the card game library
Please note this distinction. 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.
Memory and reaction activities
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. Use a clear example when reporting an error.
Bringing an issue to our attention
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.
Independent website
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. A score does not replace professional advice.
Performance varies with your setup
Please note this distinction. 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. Refer to the game page for its available format.
Play according to the displayed format
Before relying on a result or explanation, remember: 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. Results should be understood in the context of the game.
When you visit an outside destination
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. Refer to the game page for its available format.
Recreational learning and assessment limits
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. Read a destination’s own information before using it.
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. Take a break when a round stops being enjoyable.
