Although Lucky Tiger Casino just recently started in 2020, it’s managed by the company behind the already established Superior Casino. So yes, it’s a legit site that pays out real money. It’s licensed/located in Costa Rica (not listed on their website).
That said, there are better, safer options out there for players in Kentucky.
Other options include: CasinoMax, Slotland, El Royale, Bovada, BetOnline, and if you are willing to use a VPN/Cryptocurrencies, both Stake.com and Roobet are excellent choices as well.
