I loaded “Desktop Games” from the Ubuntu Mate (in 16.04.3) Welcome Software Boutique because it had Mahjongg.
When I had Mahjongg in Ubuntu 12.04, it had a dozen tile layouts. This one seems to only have one called “Easy”, otherwise it seems identical.
Where can I get the other layouts?
I installed it thus but I think it was the one I already had via "Desktop Games":
$ sudo apt install mahjongg

This what the top of my Mahjongg screen looks like when I run it. How does it compare with yours? I can't see any way of changing the layout.
