@biturbo; Firstly, why splits? A simple answer is the payout.

I don't always use conventional splits like 1, 4; 2, 5; 3, 6; 7, 10; 8, 11; 9, 12, etc. I will use 1, 4 or 4, 7 depending on past spins, hot areas and repeaters.

Each number can be used to create 2, 3 or 4 splits. With quads you have 13 options with the middle column overlapping adjacent quads so you are limited to the bet placement.

I have found that numbers in certain splits tend to appear again within a cycle. Example 25 and 26 as a split or 13 and 16 or 20 and 21 or 9, and 12 or 3 and 6 etc. If one of the numbers appears I create a split with it based on its felt neighbours with reference to recent past spins and wheel layout constantly checking for hot areas. 23 and 24 is another example. The flexibility of being able to create your own splits within a dozen is extremely valuable in relation to game trends.

On patterns of three; there are three dozens and expectation is that each one will show once within 3 spins (excluding zero). There are 29 possible pattern variations that can occur in a three spin cycle. You must have a pattern of three to bet against and that's why each game is a total of three spins. Each game of three spins creates the pattern for the next game. Three spins must take place for each game even if you only bet on one or two of the spins. It is not wrong to bet the third if you lose the first two. I prefer two bets to reduce or eliminate the use of progressions.

How to I chose the splits?

Standard selection would possibly be as follows;

Dozen one: 2, 5; 4, 7; 8, 11 and 9, 12.

Dozen two: 14, 17; 15, 18; 19, 22 and 20, 21.

Dozen three: 27, 30; 28, 29; 33, 36 and 34, 35.

If a number appears in the split not covered I either amend my selection by including that one number in my selection or I play the split the number appears in removing a split that hasn't had a number show in the last 12-18 spins. It is not an exact science but making use of past spins does help.

To be continued. ..
