Know the color groups
Red numbers are 1, 3, 5, 7, 9, 12, 14, 16, 18, 19, 21, 23, 25, 27, 30, 32, 34, and 36. The other nonzero numbers are black. Red is not the same as odd: 12 is red and even, while 11 is black and odd. Zero belongs to the green group.
Choose a number or a group
The full layout supports single numbers, splits across two numbers, streets of three, corners of four, and other supported combinations. Outside positions cover colors, odd or even, low or high, dozens, and columns. Each position covers a defined set of numbers and has its own virtual-chip ratio.
Build more than one placement
Choose a chip denomination, then tap the positions you want. You can have a number placement and a color placement active together. Undo removes the most recent chip and Clear empties the current layout. After a spin, Rebet restores the previous selection.
Compare single and double zero
Our European table has one zero and 37 pockets. American Roulette adds a separate double zero for 38 pockets. Neither green pocket belongs to red/black or odd/even. Look at the wheel and table before assuming two roulette versions have identical possible results.
Use history as a record
The recent-spin strip shows what has happened. It does not forecast the next pocket. A long sequence of one color does not make the other color due. Use the history to read the table’s results while remembering that each new spin is selected independently.
