As also stated on Wikipedia's roulette page, numbers covered by this system are called Orphelins (or Orphans) because they don't belong in either of the two main roulette systems, Voisins du Zero and Tiers du Cylindre. This French Bet  bet was traditionally referred to as 'Call Bet' or 'Announced Bet', as it was  too specialist to be featured on the main tables, and players had to call out when they wanted to play it.

Orphelins Roulette table

Orphelins (sometimes called "Orphelins à Cheval") is a 5 chips call bet, covering 8 numbers - exactly the 22% of the roulette table. It covers split bets (à Cheval) on the numbers 6/9 - 14/17 - 17/20 - 31/34 and one chip on the number 1 (En Plein).

Orphelins - how to place your bets

We obviously have only 1 out of 37 chance (2.7%) of winning with the 1. In case of 1 we have 31 chips net profit - 35 chips for the win, minus the four chips lost on the other combinations. The four two-number combinations would each give you a net profit of only 13 chips (17 chips for the win, minus the four losing chips) and pay out 5.4% of the time. Summing up, we have a total win rate of 24.3%.

Let's take a look to the math behind the Orphelins system. We consider 100 roulette spins (a 500 chips investment). On average, we have the following winnings:

  • Number 1: 35 chips x 2.7%= 94.5 chips
  • Number 6: 17 chips x 2.7%= 45.9 chips
  • Number 9: 17 chips x 2.7%= 45.9 chips
  • Number 14 :17 chips x 2.7%= 45.9 chips
  • Number 17: 34 chips x 2.7%= 91.8 chips (we have 2 chips on 17)
  • Number 20: 17 chips x 2.7%= 45.9 chips
  • Number 31 :17 chips x 2.7%= 45.9 chips
  • Number 34 :17 chips x 2.7%= 45.9 chips

Furthermore, you win, you wil get your chipsback plus and so we have to add 24.3 chips more.

So, for every 500 chips staked, you will average a 486 chips return. The house edge for the Orphelins system is 2.7%. The same as the standard house edge for every roulette game. Mathematically, this system gives you no more chance of success than a standard red/black play.

Of course, for this sysem to work, you have to get lucky quickly. In fact, "winning quickly" is the best roulette strategy. In a game with a house edge, the results deviate less from the theoretical edge the longer the game goes. The best way to skew the results is to get lucky early and walk away while you're ahead.
