Agree 100%. Used to play BJ on Oddsmaker.ag for a few years. Anytime I would play large hands $200+, they'd magically beat me by 1, I'd bust, or tie. Can't tell you how many times I had 20 & the dealer would get 20 or 21. They supposedly use a 'Random Number Generator'. I asked them what the hell is that as you can't have a RNG. It has to be based on a algorithm that surely they wrote. They didn't have much of a response. It's rigged!
I'd play just 1 deck, instead of multiple where you shouldn't see such BS results. Same thing. Lost a bunch of money I didn't have, but was 20 years ago. When I did win it took forever to get paid regardless of method. And they had a ridiculous minimum & a $25-$50 withdrawal fee! BS.
I'd get whatever money you have in your account out ASAP. Usually no regs & in bed with the country's gov their based out . No recourse! Stick with US based books. Fair, regulated, get withdrawals within hours, freebies, usually good customer service. FanDuel, DraftKings, & BetMGM I've had zero issues with. Only sports betting as casino betting isn't legal online yet in VA. MGM Resorts in MD & Charleston, WV aren't far if I really want table games. Haven't yet been to MGM in the MD Inner Harbor & it's been open for years. One of these days. Just having fun with a little sports betting. It will all be legal online in the US within a couple years.
