How do I add a replay buttom in my game?

Hello there!
I’m really new to Unity and I’m not the best to scripting. I’m just in progress to make the most simple ball game. But I really need to make a buttom where people can click on, and them the game resets. I hope it’s not to much help to ask for, but do one of you have a script to do it then i would really appreciate to get it.

Thanks alot!

To make a button: Unity - Scripting API: GUI.Button

To restart level: Unity - Scripting API: Application.LoadLevel


“I am new to unity” is not an excuse, you could easily find everything you need by just google searching.
