As you know, roulette can be a bit of a challenge. That is why you should do everything in your power to shift the odds towards your advantage. That being said, you should always look for a single-zero roulette wheel. You may not realize it, but it can improve your chances dramatically.
The reason behind this is simple, the single-zero wheel gives you better chances at hitting your number. The odds are that you have a 2.70% chance to win. This is opposed to the double-zero roulette wheel which offers a 1 out of 38 of success.
