# D`Alembert Roulette Strategy

D’Alembert roulette strategy is one of the safest roulette strategies because after losing the bets are increased by a significantly smaller amount. This system can be used by making bets on either the black or red, odd or even, 1-18 or 19-36. Mathematical calculations don’t allow using this strategy on tenths, columns or separate numbers.

### The Strategy:

When using this system you have to choose, for example, the pair and bet a certain amount on it. If you lose, you need to increase the bet by 1 unit and if you win, you need to decrease it by a unit. The math behind this is that if you have the same number of wins and losses, you will have won the amount as big as the total number of bets (see the example below)

Strategy example, if we choose the beginning bet of 5:

Bet 5 units and lose.

Bet 6 units and lose.

Bet 7 units and win.

Bet 6 units and lose.

Bet 7 units and win.

Bet 6 units and win.

Bet 5 units and lose.

Bet 6 units and win.

**When calculating it comes down to: 0-5-6+7-6+7+6-5=4**

As you can see in the example, there were 4 wins and 4 losses, but this system makes sure that if you have had an equal amount of wins and losses you will always be the winner!

#### Advantages Of This Strategy:

- No roulette strategy is safe and has some risk involved, but in this one the risk is quite small
- To use this strategy you don’t need a lot of money and, because of the small increase in bets, you will never reach the table limits

#### Disadvantages Of This Strategy:

- The possible amount of money won is quite small, knowing you’re risking with your own money
- There is a very small possibility that in the long term your win-lose ratio will be equal

#### Tips For Bigger Profits

- When using this strategy, have a limit on the maximum amount you can lose, so you don’t lose all of your money
