Let's take a look.
.VG is meant for British Virgin islands which has a population of only 30k people.
Similarly Slots.hk sold for $7500USD and Hong Kong has a population of over 7.5 million people which makes sense.
The value here in terms of searches is very low. I would say low xxx-xx imo...
Unless you can convince someone of it being a brandable name as you suggested in the post potentially meaning Vegas or videogames but tbh I think that may be a stretch.
Good luck.
