The last time I was at Vegas, my son asked one of the Palazzo floor managers if there was some way to learn blackjack, since he was curious about the game, and the manager told him they had a free schooling on blackjack at a certain time of the day.
I think the same thing may apply with learning live poker playing. Just ask one of the floor managers at one of the casinos and they should have info on learning how to play for free.
I'm not sure how long the free course will take, I'm thinking about a half hour or so, but that may depend on how many questions are asked too.
I think most casinos have game lessons. They have these short lessons on TV (some of these are really funny!) and also live lessons on the gaming floor.
I think these should be more publicized, I would like to learn about a number of games I am avoiding now because I don't know how to play them.
Yes most casino's do have lessons....some even have pratice slots you can play.
I am sure if you ask around to the casinos you can find some lessons on poker.
