Firstly please make a file called "words.txt" and place it in the same folder as the program, In the file make sure there are at least 10 words seperated on each different line then finally run the program and you will see that the string that's concealing the word isn't showing the characters that have been gueesed for some reason.

Consider what happens if the user enters non numerical characters or multiple characters. Improve your program by getting proper user input. It's mentioned numerous times here on the forum, so you shouldn't have any problems implementing it. I fixed your code and added a time check.

ah thanks, very much yeah my code was pretty messy but now you guy's solved the problem i was having im gonna go fix it up and post the program.
