Who wrote the translations? Are they correct?

The page texts were written for each language with the sudoku terms used in that language, including the grammar of places in the hints (for example "na linha" in Portuguese, "nella riga" in Italian). In Russian, Ukrainian and Greek the hints are written as "place: question" so that every place name keeps its correct form. If you notice a wording you would say differently, tell support: we improve the texts with every update.
