As an American resident, I have played at BetPhoenix Sportsbook (the one ADulay is referring to).  They payout promptly (same day in most cases *with $37 money transfer fee.  Their Live American Roulette minimums are $5 for inside and outside bets.

Bovada Sportsbook (US friendly) has live sports betting, casino (RNG) and live online poker.  *They are slow-paying *30 days to get a check, but reliable. 

Bookmaker Sportsbook (US Friendly) has a free live Blackjack game on Thursday "40oz of Love" @ 5:30pm US Central Time and on Saturdays "Bankroller" @ 1:30pm US Central.  (Must register in advance to participate).  The rest of the casino games are RNG.

Rushmore Casino (US Friendly) has a $10,000 freeroll slots tournament every Friday at 7:00pm US Central Time.  *To participate, you have to have deposited at least once*.  The freeroll runs until Sunday 1:00pm US Central.  They have RNG casino games.  (Real-Time Gaming Software)

Do you always choose UNhit and hope that it turns out in  your favor ?--Twisteruk

According to the GUT rules it is the unhit number or lesser hit of the choices that is most likely to win.

This topic has been heavily debated since many think the hit numbers tend to repeat.  Winkel maintains it's the unhit numbers/lesser hit numbers you watch.

*Because (logically) unhit numbers always decrease...

I authored that post.

G.U.T. in a Nutshell

Procedure: Basically GUT revolves around one major bet.  Smaller bets are also availiable.
In a nutshell, (the major bet) you have unhit and hit once (or more) numbers.
Unhit  //   Hit
36             0    (when you start playing)
-----------------------------------------------------------------------------------
As the numbers come in, the unhit numbers will decrease and the hit numbers will increase.
(You have to keep track of the unhit ones (which ones they are)
Unhit   //  Hit (example)
15            15
         or
16            15

Now, when the unhit numbers equal total hit numbers (preferably 18 numbers or less) it is time to bet all of the unhit numbers one time.
----------------------------------------------------------------------------------------------------------------
<<<<Smaller bets>>>>>
Of the hit numbers, you can wager when once hit, twice hit or more equal each other...
(Example)
Once hit   //   Twice Hit
8                         8
You would bet the 8 once hit numbers (one time)
