These guides are published under the PuzzleVault project name. They explain the games available on this site. They are not independent product reviews, medical advice, or evidence that playing a puzzle improves a particular ability.
Examples you can inspect
We use constructed boards to isolate a decision: where a digit can go, which move frees a tube, or what a rotation connects. A caption identifies a teaching example. It is not a screenshot of a player's session or a promise that the next random puzzle will look the same. When a specific level is used, its pack or mode is identified.
Checking a rule and checking a strategy
The current game implementation is the reference for controls, scoring and legal moves. Worked examples are compared with those rules; automated checks exercise the published examples where a result can be reproduced. A legal move or a correctly calculated score does not prove that a strategy is optimal. Suggestions are explained with their conditions and limitations.
Writing, translation and AI assistance
AI tools assist with drafting, translation and code analysis. The checks described here concern the rules and examples, not a claim that every sentence was independently reviewed by a human expert. We do not invent player interviews, play histories, specialist credentials or measured benefits. Translations offer the same subject in five languages; they are not five different investigations.
Updates and corrections
The original publication date and the latest revision date are displayed separately. We revise explanations when the game changes or a reproducible error is found. A future game update may make an example outdated, so please report a mismatch rather than assuming the article is always right.
Send a useful report
Use the contact page and include the article URL, game name, mode or level, expected result and actual result. A short sequence of moves is more useful than a score alone. Do not include passwords or private account details. Read more about the project on the about page, or return to the game guides.
