Hi @haremoongraphics , welcome to Thunkable! 
Be sure to check out our posts about How to ask Great Questions v2.0 and our Community Guidelines as you get started.
Could you please share with us what you have started so far on this project? It will be difficullt for us to assist without knowing what you have done so far.
I would also suggest searching the Community as well, as there are many previous posts about how to create a dice rolling app.
