The first mistake in underestimating the increased house edge when playing the American roulette wheel when you have an option to play the European version. For those of you who don't know, the American wheel has a zero and a double zero while the European wheel only has one zero on it. Again, the difference might seem minute but it is actually pretty significant. For U.S citizens who play at a land based casino there is not much choice. Almost all U.S based land casinos offer the American version of the game exclusively. However if you play at an online casino you usually do have a choice and for these players the advice above is of extreme importance.
All casino games have the house edge built in, but this doesn't mean that all bets are the same. Within the same game, and this doesn't apply to Roulette only, you have various choices on how and where to place your bets. You should only be taking the bets that offer the least house edge in the game you are playing. Unfortunately almost all bets offered at the roulette table have the same house edge: 5.26%. If you are playing the American roulette version you should avoid the 00-0-1-2-3 combination bet which comes with a 7.89% house edge.
Another general gambling tip is to avoid any betting systems you might have heard of. These do not work and must be avoided. Roulette is a game for which scammers love to sell their systems.
Remember that the wheel is random. Beginner players have a hard time accepting this fact and tend to make a lot of bets on numbers which in their point of view are either cold or hot. This makes no sense at all since every number has the same chance of appearing on any spin no matter the number of times it has appeared or not in the last several spins. Suffice it to say that any note taking in order to try and find patterns is useless.
If you are having a bad day, just accept it and quit. Chasing losses is one of the biggest mistakes gamblers make and it can be devastating. Never increase your betting amount when you are losing.
Try to have fun. Remember that most people around are not going to make a lot of money and you are included. If you manage to make a profit, that's great. But if you don't, try and not take it so hard since you were the underdog from the get go. Gambling is a recreational activity which most people do for fun. Always remember that.
