Orphelins: five-chip roulette sector bet

How the five-chip layout works

Net payouts: a worked example

1. 1Stake five one-unit chips using the layout above.
2. 2If 6, 9, 14, 20, 31 or 34 wins, one split returns 18 units including its stake. Subtract all five units wagered: the net result is +13.
3. 3If 1 wins, the straight-up return is 36; if 17 wins, two splits return 18 each. Either outcome gives +31 net.
4. 4Any of the other 29 numbers loses all five units. Do not record a hit as if every chip won.

Cost and risk

• Count the full five-unit cost on every spin, not just the winning component.
• Ten misses cost 50 units. Previous misses do not increase the next hit probability.
• With standard European payouts the expected net result is (6 × 13 + 2 × 31 − 29 × 5) / 37 = −5/37 units per spin.

Common mistakes

• Treating 17 as two different possible outcomes.
• Confusing a gross return with profit after the entire layout cost.
• Moving the same layout to an American wheel without revisiting the rules and probabilities.

What to record

• Check the straight-up chip and all four splits before spinning.
• Keep the five-chip layout unchanged and record total turnover.
• Compare hit frequency, net balance and longest run of misses across several sessions.

Why This Option Is Useful

It completes the sector map and is useful when comparing all racetrack coverage groups.

How To Test It In The Simulator

1. Run it beside Voisins and Tiers.
2. Compare uncovered frequency.
3. Measure variance from the straight-up component.
