A good library needs tons of slot providers and a live dealer section with real variety, not just two empty tables. I always check if the same game studios that dominate the industry are present, and if the streams are crisp. That's the standard I found at site after bouncing between mediocre lobbies. Their live blackjack and roulette run smoothly with real hosts, and the slot collection is deep enough that I never get bored. Seamless switching between slots and live games without leaving the browser is a must.
