Consider a 37 number table where the bettor receives half his bet back if zero occurs when he/she bets Red or Black.

The Probability of getting 3 correct in 3 consecutive spins is one in eight if we ignore the zero. But what to bet ?

By betting a particular chosen sequence of 3 or even 3

consecutive Blacks or Reds to be All Correct or All Wrong

we can reduce the House Edge by betting in 3s.

We let the first spin go without betting.This is our" Indicator"( trigger) of what to bet on the second spin of the three.

If the second chosen selection( our first bet) wins we then bet the resultant 2 points on the following spin .

If the first spin-which we don't bet- is wrong then we bet- as a double- the second and third spin to be wrong.

Thus we , in effect, bet the three to be correct or incorrect over the 3 spins.A 2in 8 chance (1 in 3) for which we get paid 3/1-correct odds ignoring the zero.

Now consider the chances of the zero.

If it falls on the first spin we don't lose as we haven't bet.

If it falls on the second spin we lose half a point.

If it falls on the third spin then either,

a) we lose nothing if our second bet loses as our double has lost. or,

b) we lose the win of the second spin but not our original stake so we lose -or win - nothing.

So the chance of LOSING to the zero is reduced.

How can the first spin - the "indicator spin" - be "wrong"?

Do you mean that if your first bet loses, you bet 2 on the other color for each of two more spins? Or perhaps you bet 1 on the other color on the next spin, and then let the bet ride for another spin if it wins?

Quote:scepticusThus we, in effect, bet the three to be correct or incorrect over the 3 spins. A 2 in 8 chance (1 in 3)

The last time I looked, a 2 in 8 chance is 1 in 4.

Before I continue any further, let me make sure I understand your system.

Your first spin is a non-betting "indicator" spin.

Your second spin has a bet of 1 on the same color as the first spin.

If your second spin wins, your third spin has a bet of 2 on the same color.

If your second spin loses, your third spin has a bet of 1 on the opposite color, and if the third spin wins, your fourth spin is a bet of 2 on the same color.

Never ever ignore the zero!Quote:scepticusThe Probability of getting 3 correct in 3 consecutive spins is one in eight if we ignore the zero.

There are now 27 possible 3 spin sequences and not all have the same probability of happening

looks like BBB = RRR = RBR = BBR and so on

8 of the 27 patterns have the same chance to happen in any 3 spin set. This IS so cool ;)

Now you can easily calculate if you actually do change the house edge

Well ,O.K. TDG I didn't check my post properly .It is 1 in 4 but it is still a 3/1 chance - ignoring the zero.

Once again, I may not have made myself clear.

Consider I choose to bet BOTH Red AND Black over 3 spins-the 3 to be either all reds or all black.Betting both red and black on the first spin is not advisable because (a) we won't profit and (b) a zero would incur a loss.So we avoid the first spin of the three.

If a red wins the first spin we bet 1point on red and if it wins we put 2 points on red again on spin 3. Similarly with black.

If, on the second spin black wins when I'm betting red the bet is lost and we don't bet the third spin.

In theory we are betting BOTH red and Black to win 3 in a row- a 3/1 shot ignoring the zero.

The bet is over a series of 3 spins ,there is no fourth .

Clearer now ? The question is does it reduce the whole HE over the series of three or has it been reduced ?
