The house edge in American roulette is generally about 0.5%.
This means that for every 100 bets placed, the house will win 50 times and lose 50 times. However, there are a few circumstances in which the house edge can be much higher or lower.
The most significant factor that affects the house edge is how much money is bet. The smaller the bet, the greater the house edge will be. Theoretically, if someone bets $1 million on American roulette, the house edge would be 0.
However, if that same person only bets $10,000 on American roulette, then the house edge would be 5%. This is because with a smaller bet, there is a greater chance that at least one of the Roulette balls will come up as a winning number.
Another factor that can affect the house edge is how often one plays American roulette. The more often someone plays, the smaller the chance of hitting a winning number will be and therefore the greater the chance of losing money. For example, if someone plays American roulette once a week, their chances of hitting a winning number are 1 in 21 million (0.
00000021), while someone who only plays once every few months has a 1 in 10 million (0.000010) chance of hitting a winning number.
