Crossword puzzles are the most popular games, which are widely used in education. In textbooks, they are mostly common for testing knowledge in a learning unit, in most cases being understanding as "interactive teaching games". By completing the words or phrases in the context of a crossword puzzle, and following the established rules, students not only improve their knowledge of a topic but also increase their visual literacy skills.

There are many online tools available for teachers, some will be presented in this paper, at the same time, the authors propose the development of "crossword puzzles" in the MDIRConstructor 2.0 application.
