3/2 Betting Strategy for Roulette (UK Guide)
The 3/2 betting strategy places 3 units on a colour (Red/Black) and 2 units on a column (1st/2nd/3rd).
It aims for frequent small wins, with the occasional bigger hit when your colour and column align.

How the 3/2 Strategy Works
- Place 3 units on a colour (e.g., Red) — pays 1:1.
- Place 2 units on a column (e.g., 3rd column) — pays 2:1.
- If both hit: profit +7 units (colour +3, column +4).
- If only one hits: profit +1 unit (win − other bet lost).
- If neither hits (incl. 0/00): loss −5 units.
Quick Math (EU vs US)
European (Single Zero, 37 numbers)
- Colour hit: 18/37 = 48.65%
- Column hit: 12/37 = 32.43%
- Overlap (colour ∩ column): 6/37 = 16.22% (each column has 6 red + 6 black)
| Outcome | Probability | Net Result |
|---|---|---|
| Both hit | 6/37 = 16.22% | +7 |
| Only colour | (18−6)/37 = 12/37 = 32.43% | +1 |
| Only column | (12−6)/37 = 6/37 = 16.22% | +1 |
| Neither (incl. 0) | 13/37 = 35.14% | −5 |
EV per spin (EU): (7×6 − 5×13 + 1×12 + 1×6) / 37 = −0.135 units per spin on 5 staked ≈ −2.70% (matches the house edge).
American (Double Zero, 38 numbers)
- Colour: 18/38 = 47.37%
- Column: 12/38 = 31.58%
- Overlap: 6/38 = 15.79%
Takeaway: The same staking pattern loses faster on US wheels due to the extra 00. Prefer European whenever possible.
Worked Examples (Using £3 on Red + £2 on 3rd Column)
Example A — +£7
Ball: 19 (Red, 3rd column)
- Red wins £3 (1:1)
- Column wins £4 (2:1)
- Net +£7
Example B — +£1
Ball: 1 (Red, 1st column)
- Red wins £3
- Column loses −£2
- Net +£1
Example C — +£1
Ball: 35 (Black, 3rd column)
- Red loses −£3
- Column wins £4
- Net +£1
Example D — −£5
Ball: 0 (Green) or a number in a different column & opposite colour
- Red loses −£3
- Column loses −£2
- Net −£5
How to Choose Your Colour & Column
Simple Approach
- Pick your favourite colour (Red/Black).
- Add a column you find easy to spot (e.g., 3rd column: 3, 6, 9, …, 36).
- Stick with the pair for a full session (30–60 spins) to avoid decision fatigue.
Sector-Friendly Approach
Some players choose the column that contains more of their preferred wheel sector (e.g., high numbers 25–36). It doesn’t change odds but can fit your comfort zone.
Staking & Bankroll Templates (UK Examples)

- Session: 40–60 spins, stop-loss −£40, win-goal +£25
Mid-Stakes (Comfortable)
- Bankroll: £300
- Units: £3 → £9 + £6 = £15/spin
- Session: 50 spins, stop-loss −£120, win-goal +£75
Bonus Play & Wagering Contribution
Many UK casinos give reduced wagering contribution for roulette (e.g., 10–25%) and may exclude columns or even-money bets during bonuses.
- Check terms for table cap, max bet, and excluded bets.
- Consider clearing WR on slots; then return to roulette with real-cash play.

Common Pitfalls & Myths
What to Avoid
- Chasing losses after a −5 hit with larger units.
- Switching colour/column constantly (you’ll leak EV in mistakes).
- Playing US wheels when EU wheels are available.
Reality Check
- House edge persists: Strategy does not beat 2.70% (EU) / 5.26% (US).
- Streaks happen: Expect runs that hit neither colour nor column.
3/2 Strategy — FAQ
Is 3/2 better than Martingale?
It’s safer for many players: smaller swings, frequent +1 results, and no doubling after losses. Martingale risks rapid growth in stakes and table-limit collisions.
Best wheel type?
European (single 0). The maths above is based on EU odds; US (0/00) reduces returns further.
Best session length?
30–60 spins with a defined win-goal and stop-loss. Longer sessions drift toward the house edge.
Which column should I choose?
Any — each column has 12 numbers and an even 6 red/6 black split. Choose one you can track easily.
