Tutorials for building word games (UI elements) for newbies?

Hello everyone,

I want to make a word game. I am not trying to find out algorithms or word databases. I am only interested in learning the most appropriate way to display letter boxes on screen and animate them accordingly. I have already completed Unity's 3d tutorials like Roll a ball, etc.. However they do not help me think about the most correct way for creating 2D letter objects those can be animated with effects perfectly when necessary.

I am ready to do my homework but I need your suggestions related to starting point.

Thank you so much for sharing your experiences.
