How do I unlock my Note 4?

[AC Question]

My daughter was playing a game on my Note 4 and handed it back with a locked screen. It is wanting a pin, which I do not have. I draw my password, not use a numeric pin. So, what did she do, and how do I fix it? I have tried the last four digits of my phone number, 1234, 1111, 2222 0000 and 9999. I would really hate to have to do a hard reset and lose everything.
