Hey. This mini-game exists only in English, so there could be no problems with the language. Here the manual from our discord server:
Do you know how to hack a terminal in the fallout games?
Let's say you click GAMES and it gives you 2/5, that means the password shares 2 of the letters in that word So the word GATES would be incorrect since it shares 4 letters with GAMES (G, A, E and S) but a word like BABES would possibly be the password since it shares 2 letters with GAMES (A and E)
If BABES was incorrect but tells you that it has more or less letters similar to the password then you can compare words with both GAMES and BABES to find the password
