In the US and Canada, they have Spanish 21, which is Blackjack with the tens removed (just the tens, not the Jacks, Queens or Kings), and great rules. In Australia, they have the same game, called Pontoon.
Are there any casinos in South America that have this type of game, without the tens, with the great rules?

Hey there - thanks for posting.... I don't have that detailed information (you'd probably have to contact each individual casino or visit their websites....) most are listed...

www.worldcasinodirectory.com/southamerica-casinos.asp (just pick a country on the right hand side there to get to the casino listings)

But something you might be interested in is Pagat.com which gives a lot of information on card games played in different regions of the world.
Pagat National Directory of card games displays the countries separated by continent and then in each section explains what local games are played where (and game rules, too) - it's a very interesting site!

Enjoy, Bernie
