  On single-zero tables with the racetrack option, the numbers below are
  shown in wheel order for reference; the named bets are the wagers and
  their chips are placed for you. The amount is the total stake, split
  evenly across the bet's chips.

  bet 10 on voisins       Voisins du Zero: 17 numbers around 0 (9 chips)
  bet 10 on tiers         Tiers du Cylindre: the far third (6 chips)
  bet 10 on orphelins     Orphelins: the two orphan arcs (5 chips)
  bet 10 on zero spiel    Zero Spiel: the numbers nearest 0 (4 chips)
  bet 10 on neighbors 17  Number 17 plus four numbers each side of it
                          on the wheel (9 chips)

  One wager per player per spin; a combination or call bet is still one
  wager.
  Zero and double zero lose all outside bets. Chips are spent first;
  winnings return as credits. Displayed returns include your stake;
  odds above are profit odds.

  Betting opens with the first wager and runs for the full timer, even
  alone. No bets are accepted while the wheel spins. The result shows
  the winning pocket and its real physical neighbors on that wheel.
