  Place any number of wagers on any combination of symbols. Repeated bets
  on the same symbol are allowed; each bet must meet the table limits.
  With one active player, betting has no deadline: type spin when ready.
  With two or more active players, betting opens for 25 ticks. The wheel
  spins automatically when that window ends, even if nobody bet. Spin
  cannot shorten a shared window. No new bets during a spin or respin.

  DOUBLE         1       automatic double and respin (not a betting target)

  Every one of the 51 spaces is equally likely on each spin. On DOUBLE,
  every live bet doubles and stays on its original symbol, then the wheel
  spins again automatically. This can repeat indefinitely: x2, x4, x8,
  x16, and beyond. No extra money is debited, and nothing is cashed out
  between spins. A different symbol finally settles all bets: matching
  bets return the enlarged stake plus its profit; other bets lose.

  Example: 10 on $1, then DOUBLE twice, then $1 returns 80 credits
  (40 enlarged stake + 40 profit). Your original cost was only 10.
  Receipts report the original cost and final net, not a new debit for
  each DOUBLE. Chips are spent first; payouts return as credits.

  Inspired by the Draft Kings dollar wheel, with adjusted counts and odds.
  Every target has exactly 48/49 = 97.95918367% theoretical RTP, including
  all DOUBLE respins. If E is expected return per original credit:
  E = 48/51 + (2/51) E. House edge is 1/49 = 2.04081633%.
  These integer payouts need no credit rounding, even for one-credit bets.

  The scrolling wheel slows with variable steps and pauses. The final
  display shows the winning space and four actual neighbors on each side.
  Animation does not change the odds or allow bets after a spin starts.
  Disconnecting during a spin forfeits committed wagers; before a spin,
  outstanding stakes are refunded. Shutdown recovery refunds original
  pending stakes, not unbanked DOUBLE increases. The DOUBLE chain itself
  has no cap; payouts beyond the economy's integer balance capacity are
  reported as pending recovery, never truncated or paid as a wrapped value.
