Check all the sites. I don't really know how 3-card poker works but for video poker wynnbet and betrivers have better odds than you can find in most physical casinos while betmgm and caesars have the worst. Betmgm and caesars have better promos though.

One more thing to note: I'm not sure what the current sportsbook promos are but when I signed up most of them were doing "$1000 risk free!". It's not really "risk free" because if you lose you get $1000 "free bet" back not cash and then if you lose the free bet you have nothing...but anyways...What I did was put $1000 in each of 4 different sites and then 2 of them I bet on team A and the other 2 I bet on team B. Then no matter what happens you end up with $3820ish cash from the 2 winners and $2000 in free bets from the 2 losers. At that point you're only down $180 cash so you can either bet the 2 free bets on opposite sides of another game and get a guaranteed $730ish profit overall ($910 net from the free bet winner minus the $180 you were down from the first game) or gamble with it and try 2 different games and hope to hit at least one or maybe you hit both and crush it.

It's scary because you have to put $4k in play but it really is a guaranteed $730 for not much work if you want it.

I mention it just because once you sign up and bet with a site you risk taking that option off the table since those promos are "new members only"....there are like 10 sites though so.....
