There are at least 2 ways I can think of for rigging a roulette wheel. If you alter how the table balances (such as putting something small and unnoticeable under two of the legs) then you'll probably find there is a greater chance the ball ends up on one side of the wheel than the other (or clusters around certain specific numbers) - there could even be a way to do this with two opposite legs out of alignment (on the diagonal) so a host or someone off camera can change the lean of the table every so few spins without being noticed.
There's also a possibility grooves could be added to parts of the wheel where the ball spins so its course changes as it roles (if you think of the bounce of a ball that hits a corner then it's a lot more predictable). There's probably a lot of people on both sides of a casino trying to look for these sorts of things though because it can hurt the house's edge if the wheel is a bit more predictable.
These both don't guarantee a specific number is hit though so it'll still make the outcome seem random (if not done in a way that's noticeable - someone stretching across the table to do more than pick up the ball would likely be perceived as weird at best).
But the fact is that casinos, be it online or physical casinos do not have to manipulate the roulette table before they make huge amount of money. I will say Fishy001 is only getting it not right and the day might not be a lucky day for him and he lost. Is there any good reason the table should be manipulated? To me, no good reason because any number can be taken by the gamblers.There's also a possibility grooves could be added to parts of the wheel where the ball spins so its course changes as it roles (if you think of the bounce of a ball that hits a corner then it's a lot more predictable).

But we should know that casinos do have house edge advantage which makes more games to favour them than the gamblers.
