External links and outside content
For a clear understanding of the site: 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. A score does not replace professional advice.
A collection for leisure and practice
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. Read the description for the activity you choose.
Site access and device-based 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. A score does not replace professional advice.
Tell us about an error
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. Refer to the game page for its available format.
Memory and reaction activities
Before relying on a result or explanation, remember: 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. Results should be understood in the context of the game.
Understanding a particular ruleset
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. Read the description for the activity you choose.
About the available card game sets
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. Keep the purpose of the activity in mind.
Understanding timing measurements
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. Check the relevant rule before drawing a conclusion.
Understanding educational practice
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. A score does not replace professional advice.
Independent website
Before relying on a result or explanation, remember: 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. Results should be understood in the context of the game.
