How the 2nd Dozen Bet Works
The second dozen covers 13 through 24, the middle third of the number grid.
Place the chip in the 2nd 12 box in the outside section. A win pays 2 to 1.
Zero, 00, and every number outside 13 to 24 lose the bet.
When this bet makes sense
The second dozen is the only dozen that crosses the line between low and high. Its lower half, 13 through 18, belongs to low, and its upper half, 19 through 24, belongs to high. That makes it a neutral pick for a player who wants a dozen without leaning toward either end of the layout. It is a poor match for a player who wants the dozen to reinforce a low or high bet, since only half of it overlaps either one. A player who switches between low and high during a session can leave the second dozen in place, since it overlaps each of them equally.
Mistakes to avoid
- Pairing the second dozen with high and expecting the two to reinforce each other, when they overlap only on 19 through 24.
- Choosing the middle dozen because the ball seems to land in the middle, when the dozen's numbers are spread around the wheel.
- Moving the dozen bet each spin to chase whichever dozen just hit, which does not change the odds and makes the session harder to track.
