This article will be about whether or not a roulette system can work. Ever since the invention of the game people have been trying to devise a long term system to win at roulette but most people end up failing. The reason behind the failure of most systems is because of the house edge. The house edge is created by the zeros, aka the green slots. The house edge for European roulette is 2.56% and it is difficult to overcome this edge. The way many players try and overcome the house edge is by playing a progressive system, otherwise known as the martingale. This is when you increase your bets after a loss so that when you get a win it will cover all your previous losses. Many people have faced bankruptcy because of this. When you use a progressive roulette strategy you always hit a losing run sooner or later and it’s very hard to except the loss and walk away. Many people place bets beyond their means to try and cover their losses. Another system that many players try and use is wheel bias, although this only applies to land based roulette. This is when you study a roulette wheel to see if some numbers show up more than others. If a bias is shown you then bet on the most popular numbers. Bias Systems are also unreliable. The reason for this is because some numbers will show up more than others short term and to inexperienced players this creates the illusion that there is a bias when there isn’t. A modern roulette wheel is very well made and there is almost zero bias to be found from it. This makes bias roulette systems almost useless and they are nothing more than guessing work. It is a difficult task to make a roulette strategy that works long term. Because of the steep house edge and the perfection of real roulette wheels most roulette systems end up failing long term.
