Column 3 had only four black numbers: 6, 15, 24, and 33. Now comes the interesting part Column 1 has six black numbers: 4, 10, 13, 22, 28, and 31. The column to the left starts with 1 at the top, the middle column starts with number 2, and the far right column starts with number 3. If you stand at the long end of the table with the wheel at the top, the three columns run vertically in front of you. However, something different occurs with the columns.

If you are betting on either color, they will hit on the wheel with the same frequency, just as your bet will likely hit with equal frequency when you bet on a section (1-12, 13-24, 25-36). There are 6 red and thus 6 black in each section (1-12, 13-24, 25-36) but they aren’t always red-black-red-black. Regardless of which wheel type is in action, the numbers 1-36 are always arranged in the same manner on the layout. We always advise to play on a European wheel where possible. The Green-Black Attack Roulette system works on a double zero North American wheel but is even more fun on a single zero European wheel, especially when “en Prison or la partage” is offered and a player may recoup half of any even-money bet. This system looks to take advantage of this. From numbers 2-35, there are 8 black numbers (2, 8, 11, 17, 20, 26, 29, and 35) and only 4 red numbers. In the diagram, look closely at the middle row.
