Kmuzu, you are talking about “locals” casinos. Most casinos are still built in a labyrinthe style. You also are wrong about #2. You assume he is talking about the backend numbers. It is quite easy to know the “edge” on any machine. As for pit bosses being limited, again not true. Some of the newer casinos do have table tracking but it is FAR from accurate. Also NEVER ask a dealer for strategy. Know it before you go. Multi-deck is in the casinos best interest NOT yours. Sounds are a HUGE part of the environment in casinos. It is the number one “activator” in a casino. This has been proven time and again. Some casinos DO add smells, usually it's to overcome other smells. You are WRONG about the carpets also. They ARE designed to be hard to look at, as are most ceilings. For someone who has worked in a casino, you are so not “in the know.”

NEVER play Roulette. Craps IS NOT a slow game. It does have good odds, but it's still negative, and can become VERY fast. The pass line is good, but you should take “odds.”

#1 That used to be how casinos were designed. But now a days the theory is called intimate spaces. The casino floor is broken up into small areas with centralized public facilities – bathrooms, restaurants … see Sunset Station or Red Rock Station casino
#2 Except for high utilization casinos – like Foxwoods, denomination and hold percentage have very little to do with each other. There is no way to tell hold percentage on a machine. Wheel of Fortune usually has a high hold because IGT charge a lease fee for the game. Most slot machines have a 9 to 15 percent hold .. most poker games have a 1 to 5 percent hold. Today most slot designers rely more on volatility than hold.
#3 Don't kill yourself trying to find low deck BJ. First, Shuffle Master does a great job randomizing the decks and the reshuffle usually occurs before good stats. Also, don't bother memorizing those stupid strategies. If you don't know what to do, ask the dealer – they will tell you optimal strategy.
#4 Most modern casinos have player tracking on table games so it doesn't matter. The Pit Bosses can only give you limited comps and they have to ask the floor managers or the assistant casino manager. Good luck
#5 Sounds are only part of it .. most of the behaviorism is based on visual near-miss and pattern recognition.
#6 I've worked in a number of casinos and I've never seen any smells added to help gambling. The only thing I've ever smelled is cigarette smoke.
#7 You can't just play the pass line for long in craps (unless you're betting big money) this is called masturbation and they will kick you off the game.
#8 Casino carpets look that way – because they're cheap, are durable and the pattern hides the puke stains.

Here is the only thing you need to know about gambling (other than don't gamble) Find a casino that has IGT Optimal poker, get a player card and play 5 coin Double Double. The hold percentage on Optimal Double Double is less than 1 percent.
