This system is named after the most common amount when it is used.
1.Bet € 100 for the first dozen (numbers 1-12)
2.Bet € 100 for the second dozen (numbers 13-24)
3.Bet € 10 on any 10 numbers from the third dozen.
- If you get the number of the first or second dozen, you gain just as much, how much did you put in and continue your game.
- If you get one of the 10 numbers from the third dozen, that you bet, you get 6x as much as you put on that number, in this case € 60! (probability of 1 : 3.5)
- If you get one of those two numbers that you bet or if there is a zero, you lose € 300 (probability of 1 : 12.3)
