Problems to visualize the game correctly

I am getting two different views from my game:

In the C3 preview, it's correct = image 1

But when I upload the files and check it in any browser, this is what I am getting = image 2

PS. I cannot upload images here and I don't know why

I used the memory match game tutorial for this.

Could someone please explain to me why I am getting two different views of the same game?
