In my humble opinion (ha!) Las Vegas Casino uses the most realistic appearing and sounding casino software online: PlayTech.
Their regular promotions are a $1,000 weekly cash giveaway (10 prizes of $100 each), a $20 referral bonus, and a multi-tiered Comp loyalty program. Las Vegas runs a scaled signup bonus with 100% up to $100 on the low end and $500 on deposits above $2001 at the high end. This is an average-rated average-sized casino. It is a PlayTech casino, which I prefer, but there are many PlayTech casinos with more games and better bonuses. But neither does it have anything exceptional that makes it stand out above any others. This ample mid-sized casino has all the necessary elements a satisfactory casino needs, with none of the attributes that make it undesirable. Las Vegas Casino Online is, ironically enough, based in the U.K.
