Ko9 Games: Roulette Shapes and Payouts

Count the pockets first

The named wheel has 37 pockets: 1–36 and green zero. Straight-up covers one; split two adjacent numbers on the betting layout; street three; corner four; line six. The outside red/black, odd/even and 1–18/19–36 groups each cover 18 numbered pockets. The different coverage explains why the payout per winning unit is not the same for every selection.

One example: a preset of separate bets

Suppose a preset places one unit on 20, one unit on the 5/6 split, and two units on red. Total stake is 1 + 1 + 2 = 4 units. If the ball lands on red 5, the split and red components win while the straight-up 20 loses. Add the two winning returns and compare them with all four units staked. If green zero appears, none of these three components covers it. The saved arrangement combines separate stakes; it does not change the wheel’s probabilities.

Zero is outside the even-money groups

Zero is not red or black, odd or even, or part of 1–18 or 19–36. It is a separate pocket on the wheel. Thus, even when a recent display shows a run of red results, zero remains possible and neither colour becomes due. A history display reports past outcomes; it cannot alter the next spin.

Use the named paytable

The examples follow the Play’n GO European Roulette Pro format. When reading a different implementation, use its own wheel and paytable: the same bet label can depend on a particular layout. Separate the pockets covered, the component stake and the credited return, then calculate net change from the total stake.
