One of the straight-up numbers hits: The probability of this is 27.03%, and it would result in a net gain of $6.You’d win $30, but the lost bets also amount to $30, leaving you with a 0 gain/loss. One of the Dozens bets wins: This has a 64.86% chance of occurring, and it essentially results in a push.So, after we have placed our $30 in bets, we can anticipate one of three different scenarios playing out. The zero, 22, and 25 remain open, and we pray to the gambling god that they don’t show up. You can see how the bets look using the illustration below.Īs you can see, we have wagered $10 on the first dozen (1 - 12) and $10 on the third dozen (25 - 36). We simply double the bet size after a loss and then go back to the original base stake after a win. What happens if we lose a round using the 24+8 system? Well, we follow the Martingale betting system. With 34 of 37 possible outcomes covered, we find ourselves with a 91.89% chance of winning. We are left with just two numbers plus the zero unaccounted for. This leaves a third Dozens section open in which we place $1 bets on 10 of those numbers.
You need to stake $10 each on any two of the three Dozens. The 24+8 system requires players to place multiple simultaneous wagers.
