What is a two-faced person? It is someone who is double-dealing and false. He is the opposite of what you think he is. He could be a friend or business partner who stabs you in the back. This type of person is also called Janus-faced, as a person with two characteristics modeled after the Roman god Janus. Think of those theatre faces with the smile and the frown connected together.

This is at the root of my Big Number Two-Faced Roulette System. It contains the number and its opposite. I think you’ll find this a fun system to play, despite the fact that it is not an advantage-play method.

There are traditionally two types of “big number” roulette systems: The kind that can give you an edge over a land-based or an online casino because you have discovered a wheel that is biased or off balance (a very, very rare occasion today) or you’ve discovered a number that has been hitting more frequently than others simply due to the random nature of the game. This will happen a lot. In fact, this happens all the time.

Now, there is a third kind: A number that you choose as the “big number” and then decide to bet it, perhaps along with the numbers adjacent to it or to bet against it, perhaps along with the numbers adjacent to it. These are called “opposite numbers” as they are across the roulette wheel from the “big number” and its possible compadres. The opposite numbers are known as two-faced numbers as they go against the grain of the “big number” and its fellows. 

I recommend using the scoreboard to decide what your “big number” is. If the 4 has just hit, then your “big number” is a 4 and you work from there. You can bet the 4 and whatever adjacent numbers you wish or you can bet against the 4 and whatever adjacent numbers you wish. You can also bet proposition bets such as the red or black, high or low, even or odd.

[Please note: You can choose as many adjacent numbers as you wish. I have two on either side of the “big number” and two on either side of the Two-Faced number. That makes five numbers total. You can have more or fewer. This can be an expensive way to play so I would go for fewer and not more inside numbers.]


The best proposition bets to use with this “big number” system are the even-money bets of red or black, high or low, odd or even. These pay even money. You can bet with your “big number”; that is, your “big number” is in the proposition grouping, or you can “two-face” it by betting a proposition that does not contain your “big number.” You can also go both ways; one proposition that has it and one proposition that does not have it. How many propositions should you bet? I’d go with one but no more than two.

Using the proposition bets can save your bankroll some big hits if things are going the wrong way for you. I tend to always be cautious when betting my money.

[Please note: On the charts accompanying this article the designations for the “two-faced” propositions are not based on the second category of numbers; they are merely the reverse of the first category. So if the first category is odd, red, high; the “two-faced” category will be even, black, low. That second grouping of numbers is therefore irrelevant to the propositions.]


Let’s do a quick practice using the charts that accompany this article using the double-zero wheel. The scoreboard shows that the 11 has just hit. I now check out the number on the chart:

Going along with the “big number” we have these numbers: 26, 30, 11, 7, 20. If you bet these you are going with your “big number” of 11.

You can “two-face” that number by going with its opposite group of 25, 29, 12, 8, 19. Note that these numbers tend to be straight across the wheel from your “big number.” In single-zero roulette the zero does not have a “two-faced” number.

If you wish to bet the propositions you will see that the propositions that go along with 11 are odd, black and low. The propositions that “two-face” the 11 are the even, red and high.

All the best in and out of the casinos!
