Does the James Bond roulette strategy work?

How James Bond is played

1. Each spin: 14 units on high (19–36), 5 units on the 13–18 six-line, 1 unit on zero.
2. At a $5 unit that is $100 per spin, covering 25 of 37 pockets.
3. Any of 1–12 loses everything on the table; on the American wheel, so does 00.

What 20,000 sessions show

Sessions that finished ahead were up $215.70 on average; sessions that finished behind were down $943.99. 30.3% of sessions ended because the next stake no longer fit the bankroll or the table limit.

Covering 25 pockets wins often, but the wins are small: +$40 on 19–36, +$50 on 13–18, +$80 on zero, against a $100 loss on 1–12. Every component bet carries the same edge, so the combination does too, just paid out over a larger stake per spin.

The median session lasted 30 spins. The median longest losing run was 2 spins in a row (the worst of 20,000 was 11), and one session in ten put at least $100 on the table in a single spin.

European versus American wheel

The same 20,000 seeds, replayed on a double-zero wheel. The second zero roughly doubles the edge to $5.26 per $100 wagered. Measured return goes from −$2.66 to −$5.18 per $100, and the mean session from −$136 to −$272.

The code that produced these numbers

This Lua is the strategy as Engineer mode runs it, inside the same sandbox and kernel. A test in the repository replays it against the bulk generator on fixed seeds and fails the build if the two ever disagree by a single dollar.

-- James Bond: spread 20 units across high (19–36), the 13–18 six-line, and zero.
-- Session rules shared by every 0xroulette.com/systems page:
-- $5 unit, $500 table max, walk away at +$200, and stop the moment
-- the next stake can't be covered by the bankroll or the table limit.
local UNIT, TABLE_MAX, TARGET = 5, 500, 200

local HIGH_SIX_LINE = { 13, 14, 15, 16, 17, 18 }

local function reset() end
local function settle(result) end

local function place(ctx)
  return {
    { type = "high", amount = UNIT * 14 },
    { type = "six-line", pockets = HIGH_SIX_LINE, amount = UNIT * 5 },
    { type = "straight", pockets = { 0 }, amount = UNIT },
  }
end

strategy = {}
local start, stopped

function strategy.setup(ctx)
  start, stopped = ctx.bankroll, false
  reset()
end

function strategy.bet(ctx)
  if stopped or ctx.bankroll >= start + TARGET then
    stopped = true
    return {}
  end
  local bets, stake = place(ctx), 0
  for _, b in ipairs(bets) do
    if b.amount > TABLE_MAX then stopped = true end
    stake = stake + b.amount
  end
  if stake > ctx.bankroll then stopped = true end
  if stopped then return {} end
  return bets
end

function strategy.on_spin(ctx, result)
  if not stopped then settle(result) end
end

Limitations

One bankroll, one unit size, one table limit, and one walk-away target. A bigger bankroll or a higher limit moves where a progression breaks; it does not change the return per dollar wagered. Spins are fair and independent, as on a correctly functioning wheel or a certified RNG. Physical wheel bias is a separate question, covered on Physics.
