The Red Rock and Bellagio have this game. It is a skill game of limit heads-up Texas holdem, you vs the machine and NO RAKE. Are you good enough to beat the machine? Interesting possiblities for poker players....

The game was 50c-$1 limit or $2-$4 limit. Now at Bellagio you can play as high as $10-$20 limit. The machines at the Belligo are just outside the poker room, but you can't use a slot card. The games at Red Rock are outside the buffet and you can use your slot card. The game plays SUPER agressive.
