Here is a strategy that I came up with
sitting here playing random on celtic live wheel fun money
it is a 1 column bet
if the prior spin was in dozen 1, next bet place a chip on column 1
if the prior spin was in dozen 2, next bet place a chip on column 2
if the prior spin was in dozen 3, next bet place a chip on column 3
example:
the ball just landed on 12, dozen 1
next spin place a chip on the 1st column
it is a dozen bet so a very light progression can be used
no rhyme or reason behind it
just a thought
test if you wish
Another idea to fight random with random
Whatever the dozen was, bet the opposite 2 colums
If the last spin was 17, dozen 2. Your next bet would be columns 1 and 3
If the last spin was 3, dozen 1. Your next bet would be columns 2 and 3
If the last spin was 25, dozen 3. Your next spin would be columns 1 and 2
Thinking out loud
It seems as valid as any other bet selection I know of...
