Separate from outside game brands
Please note this distinction. The site is an independent collection of browser games and explanations. It does not claim endorsement by unrelated game publishers, app stores or sports organisations. A familiar game name does not make this an official brand service. Refer to the game page for its available format.
About the intended use of the games
Please note this distinction. 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.
The limits of reaction measurements
Memory and reaction challenges are recreational activities, not medical tests or diagnostic assessments. Results depend on the game and the device used. Do not use a game result to make a health decision. Use a clear example when reporting an error.
Practice activities and qualifications
A score in a word, typing or number activity is not an educational certificate or a professional assessment. Use the explanations as practice material. Different activities may measure different parts of the task. Results should be understood in the context of the game.
Check the rules used on this page
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. A score does not replace professional advice.
The collection and its content limits
For a clear understanding of the site: 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.
Performance varies with your setup
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.
Linked pages and their information
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.
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. Take a break when a round stops being enjoyable.
The limits of access and records
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.
