ДУМИ is a free Android game developed by Mincho Kolev that falls under the educational subcategory of games. The game involves finding words that can be formed from the seven letters displayed on the screen. However, names, dialect forms, obscene words, and foreign words that are not permanently part of the language are not accepted as valid words.

To check a word, simply touch the letters in the correct order, and then tap the big "Check" button in the upper right corner. If the word is correct, the screen will display "Bravo!" and the counter on the left will increase by 1/36, indicating that one of the 36 words has been found.

There is also a "Shuffle" button on the screen that shuffles the letters, making it easier to find more words. Additionally, the "Menu" button on the screen shows a list of other buttons that allow you to sign in with Google, start a new game, surrender, share your progress, access settings, select letters, and edit the dictionary.

Overall, ДУМИ is a great word game that is perfect for training the brain and expanding vocabulary.
