63 System

This system is called "63" because, when applied to American roulette, it offers an approximate 63% chance of winning on each spin. In French roulette, which has only one zero, the probability increases to 64%, so it is also known as the 64 System in that context.

It consists of betting on two of the three dozens (or columns) available. Since each dozen contains 12 numbers and the American roulette wheel has 38 pockets, the two dozens cover 24 numbers, resulting in that 63% probability.

Betting Progression

The progression used is: 1-1, 3-3, 9-9, and 27-27. This means that if you lose, you double your bet exponentially to recover previous losses and still make a profit.

Practical Example

You bet 1 chip on the first dozen and 1 on the second. If, for example, number 12 comes up (which belongs to the first dozen), you win 2 chips on that dozen but lose 1 on the other, resulting in a net gain of 1 chip.

If you lose, the next bet will be 3 chips on each of the same two dozens. If you lose again, move to 9 and 9, and finally to 27 and 27 chips.

Required Capital

For a complete sequence (up to four levels of progression), you’ll need 80 chips per attempt. The system is designed for up to 5 attempts, requiring a total capital of 400 chips (80 x 5).

Probabilities

• American roulette: probability of total loss in one attempt (when only the unbet dozen hits every time): 1.84%
• French roulette: probability of total loss in one attempt: 1.52%
• Probability of total loss by the fifth attempt: approximately 0.5%

Final Tips

This system offers a relatively safe approach, but risk is always present. Play French roulette if possible, as it reduces the house edge. Start with small bets and stop if you lose. It’s better to come back another day in a better emotional state.

A good goal is to walk away once you’ve earned between 50 and 100 chips. Avoid being carried away by greed.
