A system of betting to even out the odds at roulette
. Bet '1st dozen'
(1-12), and 'high' (19-36). This covers 30 number
s out of 36 numbers
On a spin
in the first dozen, the gain is +1. A spin in high nets no
. The only numbers open to loss
are 13-18. This is
a very safe method
for betting (compared to most).
Odds of winning +1: 1 in 3
Odds of losing -1: 1 in 6
Odds of nothing: 1 in 2
This can also be flipped around to bet on the third dozen, low.
