THE EUROPEAN ROULETTE WHEEL HAS 37 POCKETS.
A European roulette wheel contains 0 to 36: one green zero, 18 red numbers and 18 black numbers. The wheel places them in a fixed, non-numerical order. The betting layout arranges the same numbers in a grid.
Our Rob Run roulette simulator uses this single-zero wheel. The table’s sideways orientation changes how the felt looks, while the wheel order, colours and payouts stay the same. Use this guide as a placement reference, then practise free at Lenny’s table with $1M virtual cash.
Wheel parts, without the mystery
The outer bowl and ball track surround a rotating rotor. Pockets sit beside the numbered ring, with separators between them. In a physical casino, the dealer spins the ball and rotor in opposite directions, and the pocket where the ball settles determines the result.
In our simulator, RNG selects a result and the animation presents it. The last spin, the ball animation and a streak in the history do not reveal the next number.
- Every pocket has a 1/37 chance: about 2.70% per spin.
- Zero is a full outcome, not a bonus or a void spin.
- The numbers 1-36 sum to 666. Including zero leaves that sum unchanged; it has no predictive meaning.
- The standard non-zero pocket colours alternate around the wheel. Zero sits between black 26 and red 32.
European roulette numbers in clockwise order
Start at 0 and move clockwise. The sequence wraps from 26 back to 0. An anticlockwise list reads the same ring backwards.

Lenny’s note: 17 and 20 touch on the betting grid, but are far apart on the wheel. Zero’s wheel neighbours are 26 and 32, even though 0 sits beside 1, 2 and 3 on the felt. Always ask which map you are reading.
THE ROULETTE BETTING LAYOUT IN ROB RUN.
The main grid has 36 non-zero numbers in 12 streets of three. On an upright layout, 1/2/3 form the first horizontal street and the three columns run down the table. Our horizontal Rob Run-style layout turns that map sideways: 3/6/9 sit along the top, 2/5/8 through the middle and 1/4/7 along the bottom. Labels are upright here so they are easy to read.
Outside bets
Use the labelled boxes for dozens, columns, red/black, even/odd and low/high. These cover more numbers, pay less per winning unit and always exclude zero.
Limits are per spot
Our simulator accepts $1K to $200K on each individual bet. It is not a $200K total-spin cap. Multiple spots may each carry $200K if your virtual balance can cover them.
Available chips are $1K, $5K, $25K, $50K and $100K. Combine chips to make amounts in $1K increments. Check the selected spot before spinning: a chip centred on a number and one centred on the nearby line represent different bets.
INSIDE ROULETTE BETS: PLACEMENT EXAMPLES.
In each diagram, a lime chip marks the exact betting spot and outlined cells show coverage. All examples use a $1,000 stake on one bet. “Net” means profit after accounting for that stake; “return” includes the stake coming back.
Straight-up bet
1 POCKET / 2.70% / 35 TO 1
Place a chip in the centre of 17. It covers only 17, regardless of the numbers next to it. You can make the same straight-up bet on any number, including 0.
$1K example: a hit returns $36,000 including your stake: +$35,000 net. A miss loses $1,000. Win chance: 1/37.
Split bet
2 POCKETS / 5.41% / 17 TO 1
Place the chip on the shared line between 17 and 20. Splits also work between vertical neighbours such as 17/18. A diagonal pair is not a split. At the zero end, the simulator also offers 0/1, 0/2 and 0/3.
$1K example: a hit returns $18,000 including your stake: +$17,000 net. A miss loses $1,000. Win chance: 2/37.
Street bet
3 POCKETS / 8.11% / 11 TO 1
Place a chip on the outside edge below the 16-17-18 group. A street is one complete three-number row on a vertical layout; it appears as a vertical group when the table is turned sideways.
$1K example: a hit returns $12,000 including your stake: +$11,000 net. A miss loses $1,000. Win chance: 3/37.
Corner bet
4 POCKETS / 10.81% / 8 TO 1
Put the chip exactly where 16, 17, 19 and 20 meet. This square of four grid neighbours is also called a carre. The corner bets used in the Romanovsky strategy work the same way.
$1K example: a hit returns $9,000 including your stake: +$8,000 net. A miss loses $1,000. Win chance: 4/37.
Six-line bet
6 POCKETS / 16.22% / 5 TO 1
Place the chip on the outside edge between the 13-14-15 and 16-17-18 streets. It covers both streets, six numbers in total. This is also called a double street or line bet.
$1K example: a hit returns $6,000 including your stake: +$5,000 net. A miss loses $1,000. Win chance: 6/37.
Zero trio bet
3 POCKETS / 8.11% / 11 TO 1
Place the chip at the junction of 0, 2 and 3. The other zero trio is 0/1/2. These special three-number bets pay like a street and are not the same as a split on 0/2.
$1K example: a hit returns $12,000 including your stake: +$11,000 net. A miss loses $1,000. Win chance: 3/37.
First four bet
4 POCKETS / 10.81% / 8 TO 1
Place the chip at the outside corner where the zero box meets the first street. It covers 0, 1, 2 and 3 and is also called the first four, top line or European basket. It is not the American five-number bet.
$1K example: a hit returns $9,000 including your stake: +$8,000 net. A miss loses $1,000. Win chance: 4/37.
On a standard three-column grid there are 57 non-zero splits, 22 corners, 12 streets and 11 six-lines. Our simulator also supports three zero splits, two zero trios and first four. You can inspect the individual spots in the Pattern Calculator. Corner players can then follow the Romanovsky blueprint; six-line players can try the James Bond spread.
OUTSIDE ROULETTE BETS: DOZENS, COLUMNS & EVEN MONEY.
Dozens and columns cover 12 pockets and pay 2 to 1. The six even-money boxes cover 18 pockets and pay 1 to 1. None covers 0, so even-money does not mean a 50% chance on a single-zero wheel.
Dozen bet
12 POCKETS / 32.43% / 2 TO 1
Place a chip in 2nd 12 to cover 13-24. The other boxes are 1st 12 (1-12) and 3rd 12 (25-36). Zero is excluded from all three dozens.
$1K example: a hit returns $3,000 including your stake: +$2,000 net. A miss loses $1,000. Win chance: 12/37.
Column bet
12 POCKETS / 32.43% / 2 TO 1
Place the chip in the middle 2 to 1 box to cover 2, 5, 8, 11, 14, 17, 20, 23, 26, 29, 32 and 35. The first column starts at 1; the third starts at 3. Zero belongs to none of them.
$1K example: a hit returns $3,000 including your stake: +$2,000 net. A miss loses $1,000. Win chance: 12/37.
Red bet
18 POCKETS / 48.65% / 1 TO 1
Place the chip in the red outside box. The 18 red pockets win; black and zero lose. Red is a fixed group, not the same as odd. For example, 12 is red and 11 is black.
$1K example: a hit returns $2,000 including your stake: +$1,000 net. A miss loses $1,000. Win chance: 18/37.
Black bet
18 POCKETS / 48.65% / 1 TO 1
Place the chip in the black outside box. It covers all 18 black numbers. The selected colour still has an 18/37 chance after any run of red or black outcomes.
$1K example: a hit returns $2,000 including your stake: +$1,000 net. A miss loses $1,000. Win chance: 18/37.
Even bet
18 POCKETS / 48.65% / 1 TO 1
Place the chip on Even. The winning group is 2, 4, 6 and every other even number through 36. Although zero is mathematically even, roulette excludes it from the Even bet.
$1K example: a hit returns $2,000 including your stake: +$1,000 net. A miss loses $1,000. Win chance: 18/37.
Odd bet
18 POCKETS / 48.65% / 1 TO 1
Place the chip on Odd to cover 1, 3, 5 and every other odd number through 35. Even results and zero lose. The payout and probability are identical to red/black.
$1K example: a hit returns $2,000 including your stake: +$1,000 net. A miss loses $1,000. Win chance: 18/37.
Low bet: 1-18
18 POCKETS / 48.65% / 1 TO 1
Place the chip in 1-18 to cover the lower half of the non-zero numbers. This is called manque on a French layout. Zero is not part of the low range.
$1K example: a hit returns $2,000 including your stake: +$1,000 net. A miss loses $1,000. Win chance: 18/37.
High bet: 19-36
18 POCKETS / 48.65% / 1 TO 1
Place the chip in 19-36 to cover the upper half of the non-zero numbers, called passe in French. The James Bond spread combines this bet with a six-line and a straight-up zero.
$1K example: a hit returns $2,000 including your stake: +$1,000 net. A miss loses $1,000. Win chance: 18/37.
EUROPEAN ROULETTE ODDS & PAYOUT CHART.
The probability of a standard bet winning is its number of covered pockets divided by 37. Payout odds such as “35 to 1” describe profit, not the total returned. All figures below assume one $1K bet and ordinary single-zero rules.
On small screens, scroll the table sideways.
| Bet | Coverage | Win chance | Profit odds | Net on $1K | Gross return |
|---|---|---|---|---|---|
| Straight up | 1/37 | 2.70% | 35 to 1 | $35,000 | $36,000 |
| Split | 2/37 | 5.41% | 17 to 1 | $17,000 | $18,000 |
| Street / zero trio | 3/37 | 8.11% | 11 to 1 | $11,000 | $12,000 |
| Corner / first four | 4/37 | 10.81% | 8 to 1 | $8,000 | $9,000 |
| Six-line / double street | 6/37 | 16.22% | 5 to 1 | $5,000 | $6,000 |
| Dozen / column | 12/37 | 32.43% | 2 to 1 | $2,000 | $3,000 |
| Red / black | 18/37 | 48.65% | 1 to 1 | $1,000 | $2,000 |
| Even / odd | 18/37 | 48.65% | 1 to 1 | $1,000 | $2,000 |
| Low / high | 18/37 | 48.65% | 1 to 1 | $1,000 | $2,000 |
A payout is not always a profitable spin. Put $1K on red and $1K on black: a non-zero result returns $2K on the winning side, exactly matching the $2K total stake. Net profit is $0. Zero loses both bets for -$2K. Covering 36 pockets has not created a winning system.
The house edge is 1/37, about 2.70% of total turnover. A $10K total stake therefore has an expected loss of about $270.27 per spin across many repetitions, not a fixed fee on each individual spin. More coverage changes how results are distributed; it does not remove the edge.
Our simulator has no la partage or en prison: zero loses even-money bets in full. Some French-rule tables return half an even-money stake or hold it for another spin, so always read the specific rules. American double-zero roulette has 38 pockets and a 5.26% edge on standard bets. Its five-number 0/00/1/2/3 bet has different odds and is not part of this European layout.
ROULETTE RACETRACK & THE WHEEL SECTORS.
A roulette racetrack is an oval representation of wheel order, also called the neighbour-betting area. It groups pockets by their physical positions around the wheel rather than their numerical positions on the felt. A racetrack bet ultimately becomes ordinary straight-ups, splits, trios or corners.
Voisins du Zéro, Tiers du Cylindre and Orphelins partition the wheel into 17, 12 and 8 pockets: 37 distinct numbers in total. Jeu Zéro is a smaller seven-pocket group inside Voisins. The coloured strips below identify sectors; pocket backgrounds still show the actual red, black and green colours.
Three sectors. One wheel.
Voisins covers 17 pockets, Tiers covers 12 and Orphelins covers the remaining 8. Select a sector to inspect its coverage and $1K-unit cost. Full placement recipes follow below.

Voisins du Zéro
17 POCKETS / 9 UNITS / $9,000 AT $1K PER UNIT
The large zero sector runs from 22 clockwise through 0 to 25. It covers 17 pockets using nine units, because two of its underlying bets carry two units each.
- 2 units on trio 0/2/3
- 1 unit each on splits 4/7, 12/15, 18/21, 19/22 and 32/35
- 2 units on corner 25/26/28/29
Wheel order: 22, 18, 29, 7, 28, 12, 35, 3, 26, 0, 32, 15, 19, 4, 21, 2, 25.
45.95% coverage. On 0, 2 or 3: +15 units net. On another covered number: +9 units. On a miss: -9 units. These are whole-spread results, after subtracting every unit staked.
Tiers du Cylindre
12 POCKETS / 6 UNITS / $6,000 AT $1K PER UNIT
The “third of the wheel” is the 12-pocket arc from 27 clockwise to 33, away from the large zero sector. Six split bets cover it. It is not the same as the 1st, 2nd or 3rd dozen on the felt.
- 1 unit each on splits 5/8, 10/11, 13/16, 23/24, 27/30 and 33/36
Wheel order: 27, 13, 36, 11, 30, 8, 23, 10, 5, 24, 16, 33.
32.43% coverage. Any covered number: +12 units net. A miss: -6 units. These are whole-spread results, after subtracting every unit staked.
Orphelins
8 POCKETS / 5 UNITS / $5,000 AT $1K PER UNIT
The eight “orphans” occupy two wheel segments: 17/34/6 and 1/20/14/31/9. These are the pockets left over after Voisins and Tiers. The standard five-unit recipe covers 17 twice.
- 1 unit straight up on 1
- 1 unit each on splits 6/9, 14/17, 17/20 and 31/34
Wheel order: 17, 34, 6, 1, 20, 14, 31, 9.
21.62% coverage. On 1 or 17: +31 units net. On another covered number: +13 units. On a miss: -5 units. These are whole-spread results, after subtracting every unit staked.
Jeu Zéro / Zero Game
7 POCKETS / 4 UNITS / $4,000 AT $1K PER UNIT
The small zero game covers seven pockets from 12 clockwise through 0 to 15. It is a subset of Voisins, so it overlaps that sector. Do not add its seven pockets to the 17 + 12 + 8 partition.
- 1 unit each on splits 0/3, 12/15 and 32/35
- 1 unit straight up on 26
Wheel order: 12, 35, 3, 26, 0, 32, 15.
18.92% coverage. On 26: +32 units net. On another covered number: +14 units. On a miss: -4 units. These are whole-spread results, after subtracting every unit staked.
Building these bets at Lenny’s table: our simulator has the underlying betting spots, but no one-click racetrack control. Place the recipe manually in the Pattern Calculator or simulator. This reference explains traditional European sector bets; it does not claim dedicated racetrack controls exist in the Steam game.
One “unit” means the base amount on each listed component. In Voisins, a $1K unit still means $2K on the trio and $2K on the corner. Scaling that recipe to a $100K unit reaches the $200K per-spot cap on both doubled components and costs $900K in total. The combined payout depends on which pocket wins, not just which sector is selected.
FIND A NUMBER’S ROULETTE WHEEL NEIGHBOURS.
A neighbour bet normally places equal straight-up stakes on a centre pocket and a chosen number of adjacent pockets on each side. “Two neighbours” means two on the left and two on the right, plus the selected number: five bets in total.
Pick a pocket. Follow the ring.
0 + two neighbours on each side, in clockwise order:
- 3
- 26
- 0
- 32
- 15
Five $1K straight-up bets cost $5,000. Coverage: 5/37 (13.51%). Any hit returns $36,000 gross: +$31,000 net for the whole spread. A miss loses $5,000.
For example, 17 with two neighbours each side is 2, 25, 17, 34 and 6. These numbers are scattered across the rectangular grid. A neighbour bet does not increase any pocket’s probability or predict the landing area of independent RNG spins.
RED, BLACK, DOZENS & COLUMNS AT A GLANCE.
The 18 red numbers
1, 3, 5, 7, 9, 12, 14, 16, 18, 19, 21, 23, 25, 27, 30, 32, 34, 36.
The 18 black numbers
2, 4, 6, 8, 10, 11, 13, 15, 17, 20, 22, 24, 26, 28, 29, 31, 33, 35.
Three dozens
1st 12: 1-12.
2nd 12: 13-24.
3rd 12: 25-36.
Three columns
Column 1: 1, 4, 7, 10, 13, 16, 19, 22, 25, 28, 31, 34.
Column 2: 2, 5, 8, 11, 14, 17, 20, 23, 26, 29, 32, 35.
Column 3: 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36.
Finales are another traditional announced grouping: numbers sharing a last digit. “Final six”, for example, means straight-up bets on 6, 16, 26 and 36. It is a four-bet pattern, not a special four-number payout. At $1K each it costs $4K, returns $36K on a hit and makes $32K net; it misses 33 of 37 pockets. Named combinations do not create new odds.

ROULETTE WHEEL & LAYOUT FAQ.
What is the European roulette wheel number order?
Clockwise from zero: 0, 32, 15, 19, 4, 21, 2, 25, 17, 34, 6, 27, 13, 36, 11, 30, 8, 23, 10, 5, 24, 16, 33, 1, 20, 14, 31, 9, 22, 18, 29, 7, 28, 12, 35, 3, 26. Reading anticlockwise reverses the sequence. Rotating the wheel diagram does not change which pockets are neighbours.
What numbers are next to 0 on a European roulette wheel?
The immediate neighbours of zero are 26 and 32. With two neighbours on each side, the five-number group is 3, 26, 0, 32 and 15.
Is roulette zero red, black, odd or even?
Zero is green. It is excluded from all outside bets: red/black, even/odd, low/high, dozens and columns. It can win a straight-up, zero split, trio or first-four bet that includes it.
What is the difference between a roulette racetrack and the betting grid?
The racetrack follows the wheel’s non-numerical pocket order. The rectangular grid puts 1-36 in numerical order so that chips can cover singles, splits, streets, corners and other bets. Both refer to the same 37 possible outcomes.
Are roulette sector bets available in the Rob Run simulator?
The simulator has the individual straight-up, split, trio, corner and outside spots needed to build these recipes manually. It does not currently provide a one-click racetrack. This guide is not a claim that the Steam game offers dedicated racetrack controls.
Does a neighbour bet predict where the ball will land?
No. A neighbour bet groups wheel-adjacent pockets. With independent, uniform RNG, each pocket still has a 1/37 chance on every spin. A five-number neighbour bet covers 5/37, about 13.51%.
What does 35 to 1 mean on a single number?
It means 35 units of profit plus the one unit staked is returned. A winning $1K straight-up bet therefore returns $36K gross for $35K net profit when it is your only bet.
Is Lenny’s Roulette Cheat Sheet free?
Yes. The four-page PDF is free to download without an account or email address. It contains the European wheel order, betting layout, chip placement diagrams, odds, payouts and racetrack recipes. All Rob Run examples use virtual cash.
