So we are going to take advantage of this "chances of winning" and try, a betting system with 24 numbers. The system is very simple,  and the only thing you have to do is place  one chip in the first dozen, another one in the second dozen and one chip in low numbers ( 1 to 18 ). It can also be the opposite dozens.   You are covering 24 numbers but you only win in 18 numbers.The other six numbers you don't win or loose. There are two ways to play this system;  one of them is to use the Oscar's Grind betting system,  http://www.bjmath.com/bjmath/progress/prog1.htm  and the other is the D'Alembert system, explained in the same link.  In this second system you are going to cover 25 numbers and you need 15 chips to start. As you see on the roulette drawing you cover 5 quads or the 4 numbers bet ( the one that pays 8 to 1 ). That 5 chips. Then you put 1 chip in every Split bet ( that pays 17 to 1 ). That 5 more chips. Finally you put 1 more chip in ther Split bet. That 5 more chips.   In 13 numbers you lose 15 chips. In   6 numbers you lose   6 chips. In 15 numbers you win  12 chips In   5 numbers you win    3 chips.    Every time that you lose twice in a row you add 1 more chip in every bet, that's going to be 30 chips.   If you are going to play 1 dollar chips, you need at least $500,00 bankroll. That's gambling money.   If you going to Vegas go to El Cortez Casino in the downtown area where they have 25 cent chips and a minimun of $1,00.   Other casinos in fremont street (downtown) have 50 cents chip and a minimun 0f $2,00.     The best way to play these kind of betting systems is to find one of those "Rapid Roulette" (A bunch of computer monitors where the dealer, and the wheel stand in the middle).   You have 30 seconds to set your bets otherwise it void the bets.   They have a $2.50 minimum and 50 cent chips and the most important, nobody can see what you are doing.
