22                play 22- 29
       27                 22-27 .................so on

Thank you.

I hit 124 times in 2252 spins.
The probability is 121.7.

When me and the wife went on the last cruise...the waiter we got friendly with did cruises in the summer and worked in a casino on roulette in the winter. This is exactly what he recommended.

Probability measures are between 0 and 1 so I don't understand what a probability of 121.7 is, plolp. What are you measuring?

Anyway, just to add to this a little bit - following the last 2 outcomes rather than any random 2 or even hot numbers is a sound strategy I believe, because of the "efficiency" inherent in that choice. It is easy to show that the best time to bet any number is right after it has appeared. If you graph the number of appearances vs. the gaps between appearances you will see a standard exponential decay curve, i.e. highest point on the left. So the most efficient time to bet a number is immediately after it has appeared.  This doesn't guarantee an overall winning strategy of course, just a less volatile experience I would suggest.

In 2252 spins if you play two numbers you need to touch 121.7 times.
This is the probability 2/37.
