4567 Roulette Strategy: How the 20-Number Neighbour System Works
The 4567 roulette strategy puts one chip on each of 20 numbers: four centre numbers on the racetrack, each with the two pockets either side of it on the wheel. It starts on 3, 4, 5 and 6, adds a chip to every number after a miss and takes one off after a hit, moving through five patterns. A hit makes 16 chips and a miss loses 20, so even though 54.05% of spins hit, it still loses 2.70% of everything you bet on average. In our simulation of 100-spin sessions at £1 a number with £500, the progression finished ahead in 35.5% of sessions against 38.4% for flat stakes, and ran out of money in 62.0% against 1.3%.

Quick answer
What Is the 4567 Roulette Strategy?
The 4567 roulette strategy is a 20-number neighbour bet with a +1/−1 progression. You pick four centre numbers and bet each one with the two pockets either side of it on the wheel: one chip a number, 20 chips a spin. A hit pays 35 to 1 on one chip, so you’re 16 chips up; a miss loses all 20. After a miss you add a chip to every number; after a hit you take one off and move to the next pattern. Neither changes the odds of the next spin or the 2.70% house edge.
A hit: 20 of 37 numbers
At £1 a number, the winning chip pays 35 to 1, so £36 comes back from £20.
A miss: 17 of 37 numbers
None of your 20 numbers lands, so every chip loses.
The staking
Add £1 to every number after a miss; take £1 off after a hit, never below £1.

The pattern
How to Place the 4567 Starting Pattern
Pattern A uses the centres 3, 4, 5 and 6. Each centre takes the two pockets either side of it on the wheel, not on the table, so 3 brings in 12, 35, 26 and 0. The four groups don’t overlap, so you have one chip on each of 20 different numbers.
Use the racetrack. Many online tables have a racetrack, an oval showing the wheel order, next to the layout. Clicking a number on it usually bets that number and its neighbours; set the neighbour count to 2 where you can, click the four centres, and check there are 20 chips down before you spin.
The Five 4567 Patterns
After a hit you move to the next pattern. This guide goes from A to E and back to A; some versions stop or restart after E, which doesn’t change the odds.

The maths
4567 Odds, Payouts and Expected Loss
Figures at £1 a number. “Back” is everything returned, including the winning chip; “Result” is that minus the £20 staked.
Why 54% Isn’t a Winning Rate
54.05% is the chance that one spin hits, not the chance that the system makes money. A hit wins 16 chips and a miss loses 20, so the misses cost more than the hits pay, even though they come less often.
(20 × £16 − 17 × £20) ÷ 37 = about −£0.54 a spinOn average, £320 won and £340 lost every 37 spins: a net £20 lost from £740 bet, which is 2.70%, the standard European house edge. The progression changes how much goes on each spin, not that share.
Five patterns, same odds. Every pattern covers 20 of the 37 numbers, so moving from A to B after a hit doesn’t make the next spin more or less likely to hit. The wheel doesn’t remember the last number.

4567 calculator
4567 Roulette Strategy Calculator
Pick a pattern, your starting chip, the level you’re on and a winning number. The calculator shows what comes back, what the next spin should be, and where a hit or a miss would leave you. Level 3 means three times your starting chip on each of the 20 numbers.
- Chip on each number
- £1
- Lost reaching this level
- £0
- Run if this spin hits
- +£16
- Run if this spin misses
- −£20
- Average loss this spin
- 54p
Number 26 is in the 3 group: the £1 chip on it pays 35 to 1, so £36 comes back from £20, a £16 profit. Next spin: pattern B at level 1, £1 a number.
Pattern A groups
Standard payout: 35 to 1 on a straight-up, so the winning chip comes back with 35 more. “Lost reaching this level” and the two run figures assume you got here with straight misses from level 1; with hits along the way, the totals differ. “Average loss” is 2.70% of this spin’s stake; any single spin wins or loses far more. For smaller stakes, our low-stakes roulette guide covers where 10p and 20p chips are accepted.

4567 Progression vs Flat Stakes
The same 20-number patterns, staked two ways: with the +1/−1 progression, or one chip a number every spin. Pick a bankroll, a starting chip and a session length; the simulator plays 30,000 sessions with both on exactly the same spins.
Over 100 spins, the +1/−1 progression finished ahead in 35.5% of sessions against 38.4% for flat stakes, and ran out of money in 62.0% against 1.3%. The average result was −£97.28 against −£54.46, from £3,485.17 and £1,995.17 bet on average.
A simulation of 30,000 sessions with a fixed seed, so the same settings always give the same figures. Both systems play the same spins and change pattern after the same hits; only the chips differ. A session stops when the next stake is more than the money left, and “Ran out of money” counts sessions that had to stop before their last spin. In every setting where either can run out, the progression runs out more often. With 50 or more first-spin stakes (20 chips each, so £1,000 at £1 a number), it finishes ahead more often than flat stakes; with 25 (£500 at £1), it finishes ahead more often over 25 and 50 spins but not over 100 or 200; with fewer, flat stakes finish ahead more often in almost every setting. Because it bets more, the progression’s average loss is bigger in most settings, but both lose about the same share of what they bet: 2.70% on average. Table limits are ignored.
Progression
How the +1/−1 Progression Builds Up
Each miss adds a chip to all 20 numbers, so the stake climbs by 20 chips a spin: £20, £40, £60 and up at £1 a number. Five misses in a row cost £300 and leave you needing £120 for the next spin. A hit only wins 16 chips for each chip a number, so after two or more misses in a row, one hit doesn’t get you back to even.
Over 100 spins: a 39.6% chance of at least one run of six misses in a rowThat takes the next stake to level 7 or higher: £140 or more a spin at £1 a number. The chance of at least one run of eight misses, which leaves you at least £720 down on that run and needing at least £180 a spin, is 9.7%.
It’s a D’Alembert on 20 numbers. Adding a unit after a loss and taking one off after a win is the D’Alembert staking plan. Because you only drop one level after a hit, a run that mixes hits and misses can stay at high stakes for a long time: in our default simulation, the progression’s biggest stake averaged £138.25 a session, against £20.00 for flat stakes.
Wheels
European, French, American and Lightning Tables
The 20-number patterns work as described on a single-zero wheel. French roulette uses the same wheel, so nothing changes: La Partage only covers even-money bets, and the 4567 doesn’t use any. On an American wheel the numbers sit in a different order, so pattern A covers 18 numbers, with 33 and 34 each covered twice, and the house edge rises to 5.26%.
Lightning and multiplier games: in Lightning Roulette, straight-ups usually pay 29 to 1 unless the number is struck by a multiplier, so a plain hit returns 30 chips and you’re 10 up, not 16. Check the paytable before using these figures on any multiplier game.
Compared
4567 vs Other Roulette Systems
Every system here loses, on average, the same 2.70% of what’s bet on a European wheel; what changes is the shape of the results. The 4567 hits more often than a bet on Red, but its misses cost more than its hits pay, and like the D’Alembert it raises the stake while you’re behind. The 36 strategy and Romanovsky cover more numbers at a flat stake.
Verdict
Does the 4567 Roulette Strategy Work?
It works as a set of instructions: the patterns, the 20 numbers and the results are exactly as described. It doesn’t work as a way to win: every spin loses 2.70% of its stake on average, whichever pattern you’re on, and the progression puts more money on the table while you’re behind.
UK rules
Playing the 4567 at a UK Casino
No Gambling Commission rule bans betting systems, but many casino bonuses exclude roulette or count it at a low rate, and bonus terms often restrict staking progressions or bets that cover much of the table. Winnings can be voided, so check the terms before you play with bonus money. These are the rules that shape how you play at a UK-licensed casino.
No autoplay
Autoplay is banned, so you start every spin yourself. The 4567 changes its pattern or its chips after every spin, so expect to place the bets by hand each time.
At least 5 seconds a spin
An online roulette game can’t start a new spin within 5 seconds of the last one starting, so 100 spins take at least eight minutes.
Your spend on screen
Games show your net spend and how long you’ve been playing, so you can see what the progression has really cost.
A limit before you deposit
New customers are asked to set a financial limit, such as a deposit limit, before their first deposit.

4567 Roulette Strategy FAQs
What is the 4567 roulette strategy?
It’s a racetrack system: four centre numbers, each bet with the two pockets either side of it on the wheel, so you have one chip on each of 20 numbers. It starts on 3, 4, 5 and 6, adds a chip to every number after a miss, and takes one off and moves to the next pattern after a hit. A hit makes 16 chips and a miss loses 20.
Which 20 numbers does the 3-4-5-6 pattern cover?
On a European wheel: 0, 2, 3, 4, 5, 6, 10, 12, 13, 15, 16, 17, 19, 21, 23, 24, 26, 27, 34 and 35. The groups are 12, 35, 3, 26, 0 (centre 3), 15, 19, 4, 21, 2 (centre 4), 23, 10, 5, 24, 16 (centre 5) and 17, 34, 6, 27, 13 (centre 6).
Why is it called the 4567 strategy?
We couldn’t find a reliable source that explains the name or shows where the system started, and guides describe slightly different rules. This page uses the version most of them share.
What happens after a miss?
Stay on the same pattern and add one chip to every number. At £1 a number, the stake goes from £20 to £40, then £60, and so on: 20 chips more for every miss.
What happens after a hit?
Take one chip off every number, never going below one, and move to the next pattern. This guide goes A, B, C, D, E and back to A.
Is 54% the win rate?
It’s the chance that one spin hits: 20 of 37 numbers, or 54.05%. But a hit wins 16 chips and a miss loses 20, so on average you lose about 54p a spin at £1 a number, the standard 2.70% house edge.
Does one hit win back earlier misses?
Only after a single miss. At £1 a number, one miss costs £20 and a level 2 hit wins £32, so you’re £12 up. After two misses (£60), a level 3 hit wins £48 and leaves you £12 down, and the gap grows with every extra miss.
How much money do I need for the 4567?
No bankroll makes it work; a bigger one just pays for more spins. At £1 a number, eight misses in a row cost £720 and the ninth spin would need £180. In our simulation with £500 at £1 a number, the progression ran out of money in 62.0% of 100-spin sessions.
Can I use the 4567 on American roulette?
You can, but the numbers are in a different order on an American wheel, so pattern A covers 18 numbers instead of 20, with 33 and 34 covered twice. A hit on 33 or 34 makes 52 chips, any other hit 16, and a miss still loses 20. The house edge is 5.26%.
Does changing pattern change the odds?
No. Every pattern covers 20 of 37 numbers, so each has the same 54.05% chance of a hit. Changing pattern changes which numbers you’re on, not the odds of the next spin.
Is the progression better than flat stakes?
Neither beats the house edge. In our simulation of 100 spins at £1 a number with £500, the progression finished ahead in 35.5% of sessions against 38.4% for one chip a number, ran out of money in 62.0% against 1.3%, and lost £97.28 on average against £54.46, because it bet more.
Can I use autoplay for the 4567?
Not at a UK-licensed online casino. Autoplay has been banned since January 2025, so you start every spin yourself. Because the pattern or the chips change after every spin, you’ll place the bets again each time.
Our method
How We Checked This Guide
What we checked
The odds and returns on this page come from exact roulette maths: 37 pockets on a European or French wheel and 38 on an American one, with the standard 35 to 1 payout on a straight-up. Neighbours follow the standard wheel order, two pockets either side of each centre, and we checked that every European pattern covers 20 different numbers. Descriptions of the 4567 differ and we found no reliable original source, so we use the most common version: one chip a number at level 1, one more on the same pattern after a miss, and one fewer (never below one) on the next pattern after a hit, going back to A after E. The simulator figures come from a seeded simulation of 30,000 sessions per setting. The UK rules come from the Gambling Commission, checked on 7 October 2026. We haven’t checked table limits at every casino, so check each table’s straight-up maximum.
