Most online casinos spend more effort trying to separate you from your money than they do trying to give you a good experience. They have all kinds of popup windows, they usually make you download their software, and if do they offer play-in-browser games then you have to register an account before you can play. And if you do register then they start sending you emails trying to get you to deposit real money.
But Bodog is different. They have no popup windows at all, and their practice games play right in your browser, with no download, and no registration required. You don't even have to give up your email address. It couldn't be simpler: Just one click and you're playing the game.
I wish all online casinos showed this much respect for their players. Other casinos practically ask for your first born child to play for free. Meanwhile Bodog is patient and does not twist anybody's arm to play for real money. You can play as long as you like for free with no obligation. The real-money games are available if that's your preference, but if not, you can play the free practice games for as long as you like without hassle. (Visit Bodog)

A: From the 9/6 table we see the standard deviation per hand is 4.417542. Multiply this by the square root of the number of hands and the amount bet per hand and the standard deviation is 4.42*sqrt(10)*5*$0.25 = $17.46.
A: From the 9/6 table we see the standard deviation per final hand is 6.100180. Multiply this by the square root of the number of hands and the coinage and the standard deviation is 6.10*101/2*25c*5 = $24.11.
A: From the deuces wild table we see the standard deviation per final hand is 13.405118. Multiply this by the square root of the number of hands and the coinage and the standard deviation is 13.41*sqrt(100*50)*$5*5 = $23,697.12.
A: From the deuces table we see the standard deviation per final hand is 18.349382. Multiply this by the square root of the number of hands and the coinage and the standard deviation is 18.35*sqrt(100*50)*$5*5 = $32,437.43.
A: From the top table we see the variance of the deal is 3.391375 and the variance of the draw is 24.864165. The total variance in 8-play would be 8*3.391375 + 24.864165 = 51.9952. The standard deviation is the square root of that, or 7.2108. So the standard deviation of 8 such final hands is sqrt(8)*7.2108*$2*5 = $203.95.
A: From the top table we see the variance of the deal is 3.391375 and the variance of the draw is 24.864165. The total variance in 23-play would be 23*3.391375 + 24.864165 = 102.8658. The standard deviation is the square root of that, or 10.1423. So the standard deviation of 2000 initial hands is sqrt(2000*23)*10.1423*$25*5 = $271,909.52.
