Avoid American where possible.
What This System Tries To Do
- Win small frequently on High (19–36) or Dozen 1.
- Survive zero with a small loss (−£20).
- Accept rare but heavy losses on 13–18 (−£200) as the cost of coverage.
it just spreads it differently.
Outcomes on European Wheels (Single-Zero)
| Outcome | Probability | Payout returned | Net per spin | Notes |
|---|---|---|---|---|
| Zero (0) | 1/37 = 2.70% | £350 (35:1 on £10) + £10 stake | −£20 | All other bets lose (£370) |
| Dozen 1 (1–12) | 12/37 = 32.43% | £260 (2:1 on £130) + £130 stake | +£10 | High & Six-Line & Zero lose (£250) |
| Six-Line (13–18) | 6/37 = 16.22% | £150 (5:1 on £30) + £30 stake | −£200 | Weak point of the system |
| High (19–36) | 18/37 = 48.65% | £210 (1:1 on £210) + £210 stake | +£40 | Small, frequent wins |
Expected value (EV) per spin ≈ −£10.27:
(−20×0.0270) + (10×0.3243) + (−200×0.1622) + (40×0.4865).
Five-Spin Illustration (EU wheel)
- Spin 1 → 4 (Dozen 1): +£10 • Running total: +£10
- Spin 2 → 32 (High): +£40 • Running total: +£50
- Spin 3 → 27 (High): +£40 • Running total: +£90
- Spin 4 → 17 (Six-Line 13–18): −£200 • Running total: −£110
- Spin 5 → 30 (High): +£40 • Running total: −£70
Short bursts can show profit; longer samples revert toward the negative EV.
Bankroll & Speed
- Cost per spin: £380 at the quoted stakes. Consider scaling all amounts by ½ (or less) to test.
- Live play: placing multiple chips before “No more bets” can be frantic on Speed tables. Practise on free roulette first.
- Wheel choice: EU or French. La Partage only helps outside bets, not your six-line or 0, but it softens zero on Red/High variants if you experiment.
Why the Six-Line Sinks It
With £30 on 13–18 you’re under-weighting six numbers that still appear 16.22% of the time. Every hit costs −£200. Those losses outpace the small +£10 and +£40 results over time.

36 Strategy — FAQs
Is the 36 strategy profitable long-term?
On European wheels the EV is about −£10.27 per spin at the quoted stakes. Over time, the −£200 six-line hits outweigh the frequent small wins.
Can I scale the amounts?
Yes — the system is linear. Halve/double every amount to match your bankroll. Outcomes scale proportionally (e.g., +£40 becomes +£20 if you halve stakes).
Does La Partage help?
It halves losses on even-money when zero hits. Your six-line and dozen bets aren’t helped directly, so the overall system remains negative EV.
Is American roulette OK for this?
We don’t recommend it. The extra 00 worsens results (edge 5.26%). Prefer European or French.
What’s a safer approach?
Consider higher-hit blends such as the 3/2 strategy or coverage systems like Romanovsky, and use strict stop-loss/stop-win rules.
