How the £150 Strategy Works
- Bet £50 on Dozen 1 (1–12) and £50 on Dozen 2 (13–24).
- Place £5 each on 10 single numbers from the last Dozen (25–36).
- This covers 34 of 37 numbers — leaving only three uncovered plus zero.
- Spin, record the result, and repeat. You can flat bet or use a small progression if desired.
Works best on European roulette with single zero.
Avoid American wheels where the extra 00 reduces hit rate.
Possible Outcomes
- Dozen hits: Break-even (no win or loss)
- Single hits: +£30 profit
- Uncovered number: −£150 loss
Five-Round Example (Base Stake £150)
- Spin 1: Ball hits Dozen 2 → break even.
- Spin 2: Straight-up hit (e.g. 29) → +£30 profit.
- Spin 3: Another straight-up hit → +£60 total.
- Spin 4: Ball hits an uncovered number → −£150. Net = −£90.
- Spin 5: Dozen 1 hits → break even. Final = −£90 overall.
Shows the pattern: many breakeven results, small spikes, but one miss can offset several wins.
Probability & Expected Value (European Wheel)
| Outcome | Pockets | Chance | Result |
|---|---|---|---|
| Dozen hit | 24 | 64.86% | Break even |
| Single-number hit | 10 | 27.03% | +£30 |
| Uncovered (loss) | 3 | 8.11% | −£150 |
EV ≈ −2.70% (same as the house edge). The system only redistributes outcomes into more frequent small wins and rare big losses.
Simulation: 5 Players × 500 Spins Each

| 2 | £1,210 | £650 | £890 | Loss |
| 3 | £1,480 | £600 | £950 | Loss |
| 4 | £1,330 | £580 | £900 | Loss |

Pros & Cons of the £150 Strategy
- High coverage — 91.9% of the table protected
- Simple, visual setup (easy to memorise)
- Frequent wins and breakeven results
- Large total stake per spin (£150 base)
- One uncovered hit wipes several small wins
- Long sessions drift toward the house edge
If you want a smaller-bankroll version, see the 24+8 strategy — it follows the same logic with lower risk.

£150 Strategy — FAQs
Why is it called the £150 strategy?
Because the standard layout uses £150 total per spin — £50 ×2 on two Dozens, plus £5 ×10 on singles. You can scale the unit size lower if you want to test safely.
How many numbers are uncovered?
Three numbers plus zero. Every other number is covered by your bets.
What are the chances of a complete loss?
About 8.1% per spin on a European wheel. That means roughly one in twelve spins could wipe the round.
Is this the same as the 24+8 strategy?
Yes — it’s mathematically identical, just scaled up five times. The £150 tag comes from the larger base stake version used by high-rollers.
Can it work long term?
No. It reshapes variance but doesn’t change the 2.70% house edge. Use it only for short, disciplined sessions.
