The August 2012 issue of Current Blackjack News reported the following games at $3 and some even $2:
*** Almost all $3 blackjack games include some rules/features which increase the casino edge compared to higher-minimum-bet tables. The casino edge may be anywhere from around 50% to !00% higher or worse for a player employing good basic strategy. ***
***The $3 or $2 games supposedly offered at these joints may or may not actually be available; one should not get one's hopes up, especially at peak hours. ***
