Orphelins is the third of the three standard bets used to divide a single-zero roulette wheel into named sections. crypto.games/roulette/bitcoin claims 17 numbers around zero, and the third du cylinder claims 12 numbers opposite zero. Those two sections together cover 29 pockets. The remaining eight numbers are: 1, 6, 9, 14, 17, 20, 31, and 34. They are not connected in any way. They occupy two short separate segments on either side of the wheel, positioned between the outer edges of the voisins and tiers arcs.
Which numbers fall into orphelins and why?
The eight orphelins numbers are not consecutive and do not share a single wheel region. One group sits near the single-digit section of the wheel close to zero’s boundary with voisins. The other group sits in the mid-to-high number range where tiers end and the gap before voisins begins on the other side. Grouping them under one bet name is a practical decision: rather than leaving two short, unlabelled gaps, both residual segments are combined into orphelins. This fragmented structure means orphelins cannot be placed as a clean series of identical chips, the way tiers are. Tiers uses six splits across one continuous arc. Orphelins requires a combination of bet types to cover numbers sitting in two separate wheel locations with minimum chip usage.
How many chips cover all eight numbers?
Orphelins uses five chips across five placements. One chip goes on number 1 as a straight up. The four remaining chips are placed as splits.
- Straight up on 1.
- Split covering 6 and 9.
- Split covering 14 and 17.
- Split covering 17 and 20.
- Split covering 31 and 34.
Number 17 is included in two split placements, the 14-17 split and the 17-20 split. When 17 is spun, both chips win simultaneously. No other number in the section is covered by more than one chip, so a single chip pays out for all results except 17.
What does each winning result return to the player?
Payout differs across the section because two bet types are in use. Number 1 is a straight-up paying 35 to 1. On a five-chip bet, four chips are removed as losses, and one winning chip returns 35 units plus the stake, producing a net gain of 31 units. Numbers 6, 9, 14, 20, 31, and 34 are each covered by one split chip paying 17 to 1. Net gain when any of these hits is 17 minus four losing chips, equalling 13 units from the five-chip outlay.
Number 17 is the exception. Both the 14-17 and 17-20 chips win at the same time, returning 17 to 1 on each. Combined payout from the two winning chips is 34 units plus both stakes returned. Three chips are removed as losses. Net gain is 31 units, identical to a hit on number 1 despite using splits rather than a straight up.
Win probability across the full 37-pocket wheel is 8 in 37, approximately 21.62 per cent per spin. Orphelins produces a winning result less often than tiers at 32.43 per cent and substantially less often than voisins at 45.95 per cent. House edge per chip is 2.70 per cent, the same as every other bet type on a properly structured single-zero wheel.
