Kavouras Roulette Strategy: The Exact 8-Unit Bet Layout
The common Kavouras roulette bet uses eight units across seven positions on a European single-zero table. Place 1 unit on the First Four 0-1-2-3, 2 units on the six-line 31-36, and 1 unit on each of five split bets: 8/11, 13/14, 15/18, 17/20 and 27/30.
Those seven placements produce a positive result on 20 of 37 pockets, but the result varies from +1 to +10 units and an uncovered pocket loses all 8 units. The pattern does not predict the next number or change the roulette house edge.

The numbered markers show the seven legal betting positions. The coloured coverage areas make all 20 positive-result pockets visible without covering the number labels.
Check inside-bet minimums and repeat controls
The full layout costs eight times your chosen unit, so check the minimum chip value and whether the table offers Repeat or Favourite Bet controls.

Where every Kavouras unit goes
The common base Kavouras bet is one fixed coverage pattern, not eight separate number selections. Build the following seven positions on a single-zero table and keep the relative stakes unchanged.
First Four: 0-1-2-3
Place one unit on the shared zero-area point for 0, 1, 2 and 3. This wager pays 8:1 and returns 9 units gross when any of those four pockets wins.
Six-line: 31 to 36
Place two units on the outside line joining the streets 31-32-33 and 34-35-36. Do not place two units on each number.
Five one-unit splits
Place one unit on each line between these pairs:
- 8/11
- 13/14
- 15/18
- 17/20
- 27/30
First Four is not an ordinary corner bet
The 0-1-2-3 wager covers four pockets and pays the same 8:1 profit as a corner, but it sits in the zero area rather than on a normal two-by-two number intersection. The corner-bet guide explains the distinction.
Practise the map before a timed table
Seven placements are manageable with a Repeat or saved-bet control, but they are easy to misplace under a short betting clock. Build the pattern first on free roulette, then check the controls before trying it on a live roulette table.
Every possible payout and complete spin result
Gross return includes the winning stake coming back. Net result subtracts the full eight-unit layout, including all losing positions on the table.

| Winning position | Stake | Covered pockets | Gross return | Complete net |
|---|---|---|---|---|
| First Four 0-1-2-3 | 1u | 4 | 9u | +1u |
| Six-line 31-36 | 2u | 6 | 12u | +4u |
| Any selected split | 1u | 10 in total | 18u | +10u |
| Uncovered pocket | 8u at risk | 17 | 0u | -8u |
At a 20p unit, the complete layout costs £1.60 per spin. At a 10p unit, it costs 80p. Check the table minimum rather than assuming every inside position starts at £1; the low-stakes roulette guide and 20p roulette guide explain the practical differences.

Choose a chip value and the winning pocket. The calculator identifies the winning wager, gross return and complete net result after all eight units are counted.
Check any European result
The default example uses a £1 unit and pocket 0, which wins the First Four wager.
Pocket 0 wins the First Four 0-1-2-3. The gross return is 9 units and the complete spin result is +1 unit.

| Outcome group | Pockets | Gross at selected unit | Net at selected unit |
|---|---|---|---|
| First Four | 0, 1, 2, 3 | £9.00 | +£1.00 |
| Six-line | 31 to 36 | £12.00 | +£4.00 |
| Selected splits | 8, 11, 13, 14, 15, 17, 18, 20, 27, 30 | £18.00 | +£10.00 |
| Miss | Any other pocket | £0.00 | -£8.00 |
The calculator is not a prediction tool
Changing the selected pocket only shows the accounting for that result. It does not imply that a covered or uncovered number is more likely on the next spin. Use online roulette or free play to check the placement, not to search for a hidden pattern.
Why a 54.05% positive-result rate still loses in expectation
More than half of the pockets produce a positive spin, but the 17 uncovered pockets each lose eight units. The size of the outcomes matters as much as the frequency.
Swipe sideways to compare
| Outcome group | Pocket count | Net each | Combined result |
|---|---|---|---|
| First Four | 4 | +1u | +4u |
| Six-line | 6 | +4u | +24u |
| Five splits | 10 | +10u | +100u |
| Uncovered | 17 | -8u | -136u |
| All 37 pockets | 37 | 296u turnover | -8u |
The same result appears from the normal European edge: 8 units staked per spin multiplied by 2.70% gives an expected loss of about 0.216 units per spin. Over 50 spins at a £1 unit, turnover is £400 and the long-run expected loss is about £10.81. That is an average across many repetitions, not a forecast for one session.
The broader roulette odds guide explains why changing the arrangement of standard European bets changes the distribution of results but not the underlying 2.70% edge.
Wheel choice, progressions and common variations
Use the base layout on European roulette
The map is built around the European zero area and its First Four wager. Do not copy it directly to American roulette, where 00 changes the layout and the special zero-area wager is different. The American house edge is also 5.26% on standard bets.
French La Partage does not reduce the edge on this mixed inside-bet layout because the rule applies only to qualifying even-money wagers.
The common Kavouras bet is fixed
RouletteUK calculates the eight-unit base layout shown above. Repeat the same relative stakes if you continue playing. You may see versions online that remove a position or add a staking progression, but those are variations rather than one universally agreed part of the base bet.
That makes Kavouras closer to flat betting than to a loss progression. A larger chip value increases cash exposure, not the probability of a covered pocket.
How Kavouras differs from other roulette systems
Kavouras is primarily a fixed inside-bet layout. It is more useful to compare its structure and stake movement than to assign vague labels such as low, medium or extreme risk.
Swipe sideways to compare
| System | Main type | Base stake structure | What changes after a loss? | Main practical issue |
|---|---|---|---|---|
| Kavouras | Fixed inside layout | 8u across 7 positions | Nothing in the base version | Seven accurate placements every spin |
| 3/2 strategy | Fixed outside coverage | Dozens and column bets | Nothing in the base version | Different returns depending on which area wins |
| Romanovsky | Multi-bet coverage layout | Version-specific positions | Depends on the stated version | The exact map must be defined before calculating it |
| Masse Égale | Flat even-money betting | One equal stake | Nothing | Simple result, lower total turnover per spin |
| Martingale | Even-money progression | One starting stake | Stake doubles | Rapid bankroll and table-limit pressure |
Best practical use
Kavouras is useful as a study example of how several inside bets combine into one result profile. It is much easier to place on a digital table with Repeat or Favourite Bet controls than manually on a fast live table. The main roulette strategies library separates fixed layouts from staking progressions so the maths is not mixed together.
Kavouras roulette FAQs
What is the exact Kavouras roulette bet?
Stake 1 unit on First Four 0-1-2-3, 2 units on the six-line 31-36, and 1 unit on each split: 8/11, 13/14, 15/18, 17/20 and 27/30. The total cost is 8 units across 7 betting positions.
Does Kavouras use 8 chips or cover 20 numbers?
Both descriptions refer to different things. The base layout costs 8 units and uses 7 betting positions. Those positions collectively cover 20 unique European pockets.
Is 0-1-2-3 a corner bet?
It has the same four-pocket coverage and 8:1 profit payout as a corner, but its formal table position is the First Four wager in the zero area.
What are the complete Kavouras net results?
A First Four hit leaves +1 unit, a six-line hit leaves +4 units, a selected split leaves +10 units, and any of the 17 uncovered pockets leaves -8 units.
Why does covering 20 pockets not beat roulette?
The positive outcomes are smaller than the complete eight-unit loss on an uncovered pocket. Across all 37 European outcomes, the layout loses 8 units from 296 units of total turnover, which is the normal 2.70% house edge.
Is there an official Kavouras progression?
The common public base bet is a fixed eight-unit layout. Some guides add variations or staking ideas, but there is no single progression that should be assumed unless its rules are stated separately.
Can I use Kavouras on American roulette?
The exact European map should not be copied to an American table because the 00 area changes the zero bets, and standard American roulette carries a 5.26% house edge.
How much cash does the layout cost?
Multiply the chip value by eight. A £1 unit costs £8 per spin, a 20p unit costs £1.60, and a 10p unit costs 80p. Confirm the minimum allowed on every inside position before building the layout.
Play the layout within a fixed limit
Kavouras does not become safer because it covers more pockets. Each repeated spin creates another eight units of turnover, and 17 pockets still lose the full layout. Set the cash value and stopping point before starting, and use only money you can afford to lose.
