D`Alambera system

Make a bet of $ 1. If this bet wins, the next game, leave its value unchanged. To do so and on. If the bet loses, double it - put $ 2. If this bet loses, double it - put $ 2. If this bet loses, you double your already it - put $ 4, etc. That is, losing each time, double your last bet... Thus, in the case of consecutive losses your rates should be as follows - 1, 2, 4, 8, 16, 32 and so on until you win. Then again make a single bet - $ 1, and then repeat all the above diagram again and again.
System The idea is simple - winning at any point in the game, you will win one bet, in this case, $ 1. For example, if you have lost three in a row 1 + 2 + 4, winning the fourth game of 8 dollars, to recover all previous losses and will have a profit of $ 1.
