I'm not too sure on price but I think that there are a couple of things that will help and hinder:
Help
Obviously more casino names are being bought up (many by resellers)
Gaming Law has changed in the UK over the last few years
More casinos will probably be popping up
A super casino will exist
Hinder
This particular domain is a 3 word name
I'm not that keen on my------.co.uk domains because I think that they are difficult to brand (just IMO)
For portals 'local' has worked for some. Usually for cities where there are loads of them. I'm not too sure how many casinos there'll be, or if people will take up the phrase 'local casino'.
I love casinos and I know where my local one is. If I was researching a trip away to stop over at a casino, I'd be thinking on a holiday scale rather than local.
It would be good to hear what other people think about this and other casino names. Maybe I'm completely wrong
I've watched a bunch of casino names disappear recently...
