Theres a reasonable sized group in Irvine and Largs. InIrvine you have the North Ayrshire Wargamers club which I attend. There's a healthy mix of most game types including
40k and Warmachine however Infinity is a bit less played. We meet every Sunday from 11 - 5 pm and predominantly play wargames and boardgames however there is a healthy amount of regular
RPGs. Card games not so much. You can find more details here:

At Largs you have the Bus Stop Toy Shop store. You might be better checking their Facebook page. I've only been once or twice myself and it was predominantly Card Games and
RPGs, it is quite a small shop. You can find out more here:

I think Monday night from 6.30 pm to 9.30 pm is their wargaming night.
