Board Game Arena

How can I change the size of the board on my screen? I have a fairly large display (32" running at 2560x1600), so the boards for 7 Wonders or Puerto Rico only take up about 1/8 of the screen - there is still space to use. I understand that the graphic files are larger (evident on mouse-over), how do I go about making them appear larger on my monitor? Many thanks in advance!

you could adjust the zoom on your browser.

I use chrome and it remembers the zoom per website.

OK, that was pretty stupid of me - didn't think it would improve the quality of the graphics so I discarded the simplest idea altogether. Thank you so much
