Password cracker help?

[323]

I've been playing a game called graal, and I'm getting REALLY annoyed at this guy named 'Cookie', so I was thinking of hacking him xD When you sign up, it gives you a random pass, so social engineering wouldnt work. I was thinking of trying to find his email then hack it to find his password, and then get his account banned

If anyone could help me make an email password cracker, that would be great

Thanks,

EDIT: BTW its a gmail
