This question has been, still is, and will always be asked for as long as roulette exists. Everybody wants to be more than a one trick pony and better their odds of winning at roulette, but the truth is that there is no sure shot way of beating the house in the long term. It is certainly possible to win a couple of games in a row, but hoping for the very best throughout would be stretching it.
Here’s why: if numerous accounts are to be considered, every bet you place has a 5% house edge. This means that you could lose against a casino in the long term even if Lady Luck favors you once or several times. Additionally, many players make the mistake of sitting at tables that have a 00 space instead of opting for tables that have single 0 space boards. The former almost always doubles the house edge.
To elaborate on the ‘0 point’ in roulette- this number is green and doesn’t classify as red, black, even, or odd. This means that if you hypothetically bet $10 on the last four or a 1-12, 13-24, or 25-36, you could be set back by $70 in the long term at least once every 19 times (if you hit either 00 or 0). To sum up, you would end up spending a total of $1330 on bets even if you win $1260 via a few games.
That said, there’s no reason to be disheartened. It’s just about having realistic expectations. No roulette strategy or system is completely fool proof. At best, they can better your chance of winning every now and then. It’s also about knowing when it is the right time to quit- and that is when you have made satisfactory profits in a number of games. The amount you win must outweigh the amount you lose.
