Roulette itself has been in existence for around 300 years. Yet for all its popularity in much of the world, the North American gambling world does not seem to have taken to it quite as much as their European counterparts. Whilst it can be imagined to be in the centre place of the Vegas casinos, it is in fact more popular in Europe. There are various arguments as to why this is the case. One is that the house edge of the casino in Europe tends to be much lower than those in America - four times less, in fact. Another argument is that the tastes vary simply according to cultural differences.
