What to know about game availability
For a clear understanding of the site: 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. The contact form is available for questions.
About information on linked websites
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. Check the relevant rule before drawing a conclusion.
Reporting issues in games or instructions
Keep this limit in mind when playing. 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. Read the description for the activity you choose.
Different versions and their rules
For a clear understanding of the site: 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.
For recreation
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. A score does not replace professional advice.
Timing and performance
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. Use a clear example when reporting an error.
Levels and card games included here
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. Read the description for the activity you choose.
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. A score does not replace professional advice.
Understanding educational practice
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. Read a destination’s own information before using it.
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. Use a clear example when reporting an error.
