Q) Patrick asks. With online roulette, its just a computer-generated number, how do you know whether or not this is rigged?
A) There are two main reasons to think that online roulette is perfectly fair.
Firstly, there is no reason for them to ‘rig’ the game anyway. With the 2.7% house edge, they will win in the long run, so all they have to do is put on a fair game and they will win.
Secondly, even if there was a greedy casino that wanted to rig the game so that they won money off the player quicker, it would show up in the audits. All reputable casinos have independent auditors, audit their payouts. For example Gaming Laboratories International audit Bet365. In October 2020, the audited results show
GLI’s Game Payout Calculations resulted in summary payout percentages for the listed game categories:
|96.79%||Slot Machine Games|
|96.60%||Video Poker Games|
|106.96%||Fixed Odds Games|
|97.19%||Live Dealer Games|
|97.11%||Overall (All Games)|
These values do not reflect the payout percentage of any individual game. Instead, they represent the payout percentage overall games within the category. With table games at 99.99%, looks like Bet365 had a bad month. In the long run, the payouts will tend to the expected value of the game which in the case of roulette is 97.3%,
