Contrary to public opinion, there's no guaranteed method that can give you an edge over the casino in roulette. Regardless of this fact, there's a good chance there are more gambling programs for roulette than every other casino game roulette. However, roulette is a game entirely based on random probability, and every new spin of the wheel is an isolated event of chance - totally independent of any previous spins.
Bearing this in mind, there are some systems invented which may improve your roulette play, however not one of these will ever remove the house roulette edge of 2.70%.
The first system involves using the three columns on the table each containing 12 numbers - one third of the field not counting zeros. The first column consists of six Red and six Black numbers, the second column consists of four Red and eight Black roulette, and the third column contains eight Red and four Black. You place a Color Bet on either Black or Red, then another wager in the column that contains only four of the same colour - that is, if you bet on Red, you should also place a bet within the second column casino games (containing four Red and eight Black), and if you bet on Black, place an additional bet in the third column.
If your colour comes up (which it has a 48.6% chance of doing) you will get an even return on your bet. If one of your numbers from your column comes up (32.4% chance) you will make one unit profit. If both your number casino games and the column come up (10.8% chance), you will make three units profit. Keep this system going until you are ahead.
Since the casino house will always have the advantage, the longer you play, the more you'll lose. The second method is a system for a 'quick' win.
Choose seven numbers and bet one unit on every number casino games. If they all lose, then bet the numbers once again up to a maximum of three times. If you do not win in three spins then abandon the table.
However, should you do win, distribute your winnings (35 units) over these same seven numbers. You'll now have five units on each number. If you win once again then distribute the winnings over the exact same numbers again. You should now have 35 units on each number casino games. After this bet, quit and walk away. Your highest possible win is 945 units, whilst your highest possible loss is 21 units.
A lot of roulette methods are a variation of the well-known Martingale system, which may sound good in theory, but hardly ever works as well in reality.
The theory is that a person should initially place one unit on an even chance bet (such as Red or Black, Even or Odd casino games, and Low Numbers or High Numbers). If the bet loses, then place two units on the same spot. If this loses, you double the bet again and place 4 units, then 8 units, 16 units and so forth, until the bet wins. The theory is that the bet must win at some point and you will recover all your losses and add an even money win onto the original wager.
Nevertheless, this theory breaks down as the odds are not exactly 50-50; there is the zero to take into consideration, which actually makes the odds 18-19, or 48.6%. Another problem is that a losing streak can force some progressively large bets, and you'll rapidly reach the house limit. At this time, you will no longer recover your losses on a win and you could stand to lose a significant amount of money. This is not to be recommended.
