The online roulette wheel can be said to be fixed in the sense that the wheels in the game are predetermined on which number to land on just at the press of the “spin” button. This mechanism of the game is possible by the help of the casino software that utilizes the use of a Random Number Generator (RNG) to choose the destination of the wheels. Therefore, the spinning of the wheel around the table with the appearance that it may likely land on any number is fairly the design of the game. However, the understanding of the fixed wheels mechanism of roulette should not have an effect on the odds of the player at the table.
No chance of fraud whatsoever
The fact that online roulette already knows the landing position of the wheel at the press of the button at the beginning of the game does not mean that the machine is in a position to fraud the players. This is to say that the resultant position of the wheel cannot be determined by where you place your chip but where the RNG had determined the wheel to land. Therefore, the result of the spin is always 100% random and there is no physics involved unlike at a live casino.
Why do people complain if on a losing streak? Lack of knowledge in how online roulette works and the nature of the game is the reason. Naturally, it is easier for players to feel like the game is unfair purely on the fact that electronics and the RNGs are involved rather than the tangible table in real life casinos. It is therefore advisable that you understand the viewpoint of this kind of people when they are complaining about a game so that you can always take their skeptics with a pinch of salt.
