cuadradomagicodefoz.com is a Spanish-language personal project site centered on “El Cuadrado Mágico de FOZ,” or the FOZ magic square. It is based on the classic 4x4 magic square, where combinations of four numbers across rows, columns, diagonals, and other patterns add up to 34. On top of that, it adds a four-color constraint—red, yellow, blue, and green—requiring that the relevant four-number combinations do not repeat colors. The site also extends the idea into a math puzzle format called FOZUDOKU, as well as applications for demonstrating mathematical magic tricks using a 48-card Spanish deck.
The site mainly offers conceptual explanations, historical background, gameplay instructions, Excel file downloads, printable card materials, and links to several YouTube tutorial videos. Its focus is not on being an interactive online app, but rather a resource library and teaching entry point that helps users understand how to construct, demonstrate, and solve the FOZ magic square / FOZUDOKU.
Based on the crawled content, the site provides “FOZUDOKU” downloads, new and old Excel files, card designs, and explanatory materials. There are no visible payment, membership, or purchase options, so it can generally be considered a free resource site.
The main strength is its highly distinctive theme, combining mathematics, color logic, cards, and magic. It could work well for fun classroom activities or parent-child puzzle games. The resource formats are also practical, including Excel files and printable materials. The downsides are also clear: the pages feel dated and loosely organized; the content is primarily in Spanish; the tutorial videos rely on YouTube; and it lacks modern online puzzle libraries, automatic answer checking, mobile-friendly interaction, and a structured course design.
It is suitable for math teachers, puzzle enthusiasts, parents, children’s educators, and anyone interested in mathematical magic or Sudoku variants. If you are simply looking for a standard Sudoku platform or a complete math curriculum, it is not the best fit.
The domain itself is likely accessible, but much of the instructional content links to YouTube, and the availability of the Excel downloads would need to be tested in practice. For users in mainland China, it should therefore be rated as “partially restricted”: the website may open, but the video-based learning component will usually require a proxy tool.
