Understand and test the Romanovsky roulette strategy with our free calculator. Explore the bet layout, calculate your stake and payouts, and see how covered numbers and danger numbers affect your results.

Choose European or American roulette, set your unit value, and inspect what each possible number returns. You can also simulate a session using play money or compare Romanovsky with other roulette betting systems.

01

How the Romanovsky roulette system works

The Romanovsky roulette system combines two dozen bets with two corner bets to cover 32 numbers. In the 3-3-1-1 preset shown here, you place three units on each dozen and one unit on each corner, staking eight units in total.

The two dozens cover 24 numbers. The two corners cover another eight numbers in the remaining dozen, without overlapping the selected dozens or each other.

On a European wheel, that leaves five of the 37 pockets uncovered.

When a covered number lands, one of the four bets returns nine units, including its winning stake. Because the complete layout cost eight units, the net result is a gain of one unit.

When an uncovered number lands, none of the bets wins. The net result is a loss of eight units.

3+3+1+1= 8 units

Coverage, not prediction

Romanovsky changes how your money is distributed across the betting layout. It does not predict the next number or change the probability of any pocket being selected on a fair wheel.

The same is true after a sequence of wins or losses. An uncovered result does not make a covered number due on the next spin.

You may also see the strategy called the Romanosky roulette system. This page uses Romanovsky and identifies the exact preset behind its calculations.

How to use the calculator

  1. Select European or American roulette.
  2. Set the value of one betting unit.
  3. Inspect the four bets and total stake.
  4. Select a number to examine its payout, or test a random spin.
  5. Track the net result across the entire layout.

The calculator shows the result of a defined bet arrangement. The simulator extends that calculation across a sequence of play-money spins.

02

Romanovsky Strategy bet layout: where to place your chips

The preset used on this page places two larger bets on dozens and two smaller bets on corners.

A dozen bet covers 12 numbers and pays 2:1. A corner covers four adjacent numbers on the betting table and pays 8:1.

The 3-3-1-1 preset

BetPlacementStake
First dozenThe 1st 12 box, covering 1 to 123 units
Second dozenThe 2nd 12 box, covering 13 to 243 units
Corner AThe intersection of 25, 26, 28 and 291 unit
Corner BThe intersection of 32, 33, 35 and 361 unit
TotalFour separate bets covering 32 numbers8 units

The different stake sizes are important. The dozen bets pay less per unit than the corners, so they receive three units each. With these proportions, every covered outcome produces the same nine-unit total return.

Two 3-unit dozen bets, a 1-unit corner on 25, 26, 28, 29 and a 1-unit corner on 32, 33, 35, 36
Exactly four bets. Dozens pay 2:1; corners pay 8:1. The highlighted boxes and chip markers show placement, not pocket colour.

Which numbers are not covered?

On the European preset shown here, the uncovered numbers are:

0, 27, 30, 31 and 34.

If any of these numbers lands, all four bets lose.

On American roulette, 00 is an additional uncovered result.

These are the danger numbers for this particular layout. Choosing different dozens or corners can change the uncovered-number list.

Can you use a different layout?

Different placements can preserve the same general two-dozen and two-corner structure.

However, the corners must add eight distinct numbers outside the selected dozens to maintain this preset's 32-number coverage and uniform +1/-8 result pattern.

If bets overlap or their proportions change, the coverage and net results need to be calculated again. The name of the strategy alone is not enough to determine the payout.

03

Romanovsky payouts and profit examples

The romanovsky roulette strategy explained with examples.

A winning bet's payout is only part of the result. The other bets placed on the same spin must also be included.

Total return versus net profit

Total return is the money returned from winning bets, including their returned stakes.

Net result is the total return minus everything staked on that spin.

For this preset:

9 units returned - 8 units staked = 1 unit net profit.

An uncovered result returns zero:

0 units returned - 8 units staked = 8 units lost.

Example with $1 units

The two dozen bets cost $3 each, and the two corners cost $1 each. The total stake is $8.

Number that landsWinning betTotal returnNet result
17Second dozen$9+$1
25Corner A$9+$1
0None$0-$8

If 17 lands, the $3 dozen bet pays $6 in winnings and returns its $3 stake. The other $5 of bets loses. The complete spin still finishes at +$1.

If 25 lands, the $1 corner bet pays $8 in winnings and returns its $1 stake. The remaining $7 loses, again leaving +$1 overall.

Example with $5 units

Increasing the unit value scales every amount:

ResultAmount
Each dozen bet$15
Each corner bet$5
Total stake$40
Total return on a covered number$45
Net gain on a covered number+$5
Net loss on an uncovered number-$40

The probabilities do not change when the unit value increases. The amounts won and lost do.

How one loss offsets eight wins

Eight covered-number wins produce a total gain of eight units. One uncovered-number loss costs eight units.

The following shorter example shows why counting wins can be misleading:

SpinNet resultRunning result
1: covered number+1 unit+1 unit
2: covered number+1 unit+2 units
3: covered number+1 unit+3 units
4: covered number+1 unit+4 units
5: covered number+1 unit+5 units
6: uncovered number-8 units-3 units

Five wins and one loss still produce a negative session result.

THE SIX-SPIN EXAMPLE

Still finish behind.

Five covered hits add +5 units. One uncovered number takes 8 units back.

THE EUROPEAN 3-3-1-1 EXAMPLE

The selected European layout covers 32 of 37 equally likely pockets.

Its covered-number probability is:86.49%32 ÷ 37 = 86.49%.+1 unit net on a covered hit
Its uncovered-number probability is:13.51%5 ÷ 37 = 13.51%.-8 units net on an uncovered hit

These percentages describe each spin. They do not guarantee that a particular session will contain exactly that proportion of covered results.

Winning a spin versus winning a session

One spin

In this preset, every covered number produces a positive net result on that spin. Its profitable-spin probability is therefore also 86.49% on European roulette.

The whole session

Finishing a session ahead is a different question.

The session result depends on how many +1-unit gains and -8-unit losses occur. Frequent small gains can be outweighed by fewer larger losses.

For a fixed sequence of completed spins:

THE WHOLE-SESSION EQUATION

Net result in units = covered hits - 8 × uncovered hits.

The simulator shows how those individual results combine.

Why the house edge remains

Consider all 37 possible European outcomes:

  • 32 outcomes return a net gain of one unit.
  • Five outcomes return a net loss of eight units.

The average net result is:

EXPECTED NET / SPIN-8/37 units

(32 × 1 - 5 × 8) ÷ 37 = -8/37 units per spin.

That is approximately -0.216 units per spin.

Because eight units are staked, the expected loss is approximately 2.70% of the amount wagered. The high coverage has not removed the standard house edge for these bets.

What expected loss means

With $1 units, the layout stakes $8 per spin.

Across 100 completed spins at that fixed stake:

Total amount wagered$800
Expected net result-$21.62approximately, over 100 completed spins

This is an average across hypothetical repetitions. One session may finish ahead or lose considerably more.

It also assumes all 100 bets are completed. A finite bankroll or stopping condition can end a simulation earlier.

05

Simulate a Romanovsky roulette session

Use the session simulator to explore how the layout affects a bankroll over repeated spins.

Choose a starting bankroll, unit value, roulette type and planned number of spins. Optional stop conditions let you examine what happens when the session ends at a loss threshold or profit target.

The simulation uses play money. It does not place bets or predict real roulette results.

Optional session limits
Blank means no stop-loss.
Blank means no profit target.
Blank means no table limit.

Funds and total-spin table limit are checked before each complete bet. Stop-loss and profit target are checked after settlement; a loss may cross your threshold.

Understanding your results

Ending bankrollThe balance remaining when the session stops
Net profit or lossEnding bankroll minus starting bankroll
Completed spinsHow many bets were actually placed
Total wageredThe sum of all stakes placed
Covered resultsSpins producing a gain in this preset
Uncovered resultsSpins losing the full layout stake
Maximum drawdownThe largest decline from a previous bankroll peak
Stop reasonWhy the simulation ended

One successful run is one possible outcome, not proof that the strategy has a positive expectation.

Look at the losses, amount wagered and stopping conditions as well as the final balance.

Why a session can end with money remaining

The next complete Romanovsky bet requires eight units.

If the remaining balance is smaller than that amount, the simulator cannot place the full preset. It can therefore stop with a positive balance.

That is different from losing every unit in the bankroll.

06

Romanovsky vs other roulette systems

Romanovsky mainly determines which numbers your bets cover. Martingale, Fibonacci, D'Alembert and Parlay mainly determine how stake size changes between spins.

These approaches affect different parts of the betting process. A useful comparison must specify both the bet selection and the staking rules.

Overview of the systems

SystemMain approachStake behaviourMain risk
RomanovskyCover 32 numbers using four betsFixed 3-3-1-1 layoutFull-stake losses offset small gains
Flat bettingRepeat the same selected betFixed stakeLosses can accumulate
MartingaleIncrease after lossesDouble after a loss, reset after a winStakes can grow rapidly
FibonacciFollow a staking sequenceAdvance after losses and step back after winsLosing runs increase exposure
D'AlembertAdjust the stake graduallyAdd a unit after a loss, remove one after a winStakes can still become substantial
ParlayReinvest winningsIncrease after winsA loss can remove accumulated gains

Romanovsky vs Martingale

The Romanovsky preset repeats the same total stake each spin. Martingale increases the next stake after a loss, usually by doubling an even-money bet.

For example, a Martingale progression beginning at eight units can require stakes of 8, 16, 32 and 64 units after successive losses.

Romanovsky's exposure comes from placing eight units on its layout each spin. Martingale's exposure can increase rapidly through a losing sequence.

Neither approach changes the underlying roulette probabilities.

Romanovsky vs Fibonacci

Fibonacci uses a sequence such as 1, 1, 2, 3, 5 and 8 to determine stake size.

The comparison preset advances one position after a loss and moves back two positions after a win, with a minimum of the first position.

Romanovsky's fixed preset has no such progression. Its chip distribution and stake remain unchanged unless the unit value is changed.

Romanovsky vs D'Alembert

D'Alembert increases an even-money stake by one base unit after a loss and reduces it by one after a win, subject to a minimum stake.

Its adjustments are smaller than Martingale's doubling steps, but repeated losses can still create substantial exposure.

A more gradual increase does not eliminate the house edge.

Romanovsky vs Parlay

A parlay reinvests winnings instead of increasing stakes after losses.

The comparison here uses a defined three-win preset: it reinvests the full winning return and resets after a loss or three consecutive wins.

That produces a different pattern from Romanovsky's repeated fixed layout. A parlay risks returning accumulated gains, while Romanovsky accepts small covered gains alongside larger uncovered losses.

Compare the systems using the same spins

The default comparison starts the systems with equal initial total exposure.

If Romanovsky uses a $1 unit and stakes $8, the even-money comparison systems begin with an $8 base bet.

That equalises the first stake. It does not keep later stakes or total turnover equal once progressions begin.

Within a comparison run, each system receives the same sequence of roulette outcomes.

Compare:

  • Net result.
  • Ending bankroll.
  • Total amount wagered.
  • Largest stake.
  • Maximum drawdown.
  • Completed spins.
  • Reason stopped.

Read the displayed rules and limits alongside the result. A system that finishes ahead in one run is not automatically the best system for other sequences or settings.

Same spins. Different staking rules.

The Romanovsky stake is eight times its unit value. Each other system starts with that same total stake and bets on red. Zero and double zero lose. First stakes are equal; later exposure and total turnover are not.

Optional session limits
Blank means no stop-loss.
Blank means no profit target.
Blank means no table limit.

Does any roulette betting system beat the house edge?

Under the standard rules modelled here, none of these systems removes the house edge.

They can change the frequency and size of wins, the amount wagered and the way a session ends.

A higher percentage of winning spins is not the same as a higher expected return. Likewise, systems with the same house-edge percentage can have different expected cash losses if they wager different total amounts.

07

Romanovsky danger numbers and risks

The danger numbers are the outcomes not covered by the selected layout.

For the European preset on this page, they are 0, 27, 30, 31 and 34.

An uncovered result loses every chip placed on that spin.

Why frequent wins can feel misleading

A series of +1-unit results can make the layout feel more forgiving than its loss size suggests.

However, a single uncovered result removes eight units. Increasing the unit value magnifies both amounts without improving the probabilities.

Keep the total stake and uncovered loss visible when reviewing a simulation.

Uncovered results can occur close together

On European roulette, the chance of an uncovered result is 5/37 on every independent spin.

There is no schedule requiring losses to be evenly spaced. They can occur consecutively or after a long run of covered numbers.

Across ten planned independent spins, the probability of at least one uncovered result is:

1 - (32/37)^10 = approximately 76.59%.

That is the probability of encountering at least one uncovered result. It is not the probability of losing the entire bankroll or finishing the session behind.

Practical strengths and limitations

The fixed layout is straightforward to inspect once the four bets are understood. Its repeated stake also makes the result of each pocket easy to calculate.

Its limitations are equally clear: gains are small relative to a full-stake loss, several bets must be funded each spin, and the expected value remains negative.

08

Bankroll management, unit size and session limits

Your unit value is the size of one chip unit in the model. It is not the total amount placed on the table.

For this preset:

Total stake per spin = 8 × unit value.

Understand your exposure

With $1 units, one spin risks $8.

If the starting bankroll is $100, that stake represents 8% of the starting balance. With $5 units, the same layout risks $40 per spin.

These are calculations, not recommendations that either percentage is safe.

At least eight units are needed to place one complete layout. Having enough for one bet does not protect against subsequent losses or guarantee a positive session.

What stop-loss and profit targets do

A stop-loss defines a loss threshold at which the session should end. A profit target defines a gain at which it should stop.

They control when betting ends. They do not change the probability or payout of the next spin.

If a simulator checks a stop-loss only after settling a spin, the final loss can exceed the chosen threshold. For example, a full eight-unit loss may take the balance past a smaller remaining allowance.

Read the simulator's stopping-rule explanation before interpreting its results.

Avoid treating larger stakes as a solution

Increasing the unit value after a loss changes the financial exposure.

It does not make a covered number more likely or undo the negative expected value.

Track the complete net result, including earlier losses, instead of judging a recovery attempt by its most recent winning spin.

Use play-money testing to learn the layout

The simulator lets you examine placements, payouts and stopping conditions without placing a real-money wager.

European vs American roulette for Romanovsky

European roulette has 37 pockets: numbers 1 to 36 and a single zero.

American roulette has 38 pockets because it adds double zero.

The same 32-number layout therefore covers a smaller proportion of an American wheel.

MetricEuropeanAmerican
Total pockets3738
Covered numbers3232
Uncovered numbers56
Covered-number probability86.49%84.21%
Full-stake loss probability13.51%15.79%
House edge for this layout2.70%5.26%

The chip ratio does not need to change for this comparison. The additional 00 pocket is simply another outcome on which all four bets lose.

These figures assume standard payouts without special zero-return rules.

Romanovsky roulette FAQ

What is the Romanovsky roulette system?

It is a coverage-based roulette strategy combining multiple bets on the same spin. The 3-3-1-1 preset shown here uses two dozens and two corners to cover 32 numbers with an eight-unit total stake.

Is Romanosky the same as Romanovsky?

Romanosky is a commonly used spelling variant for the strategy discussed here. You may also encounter Romanowski. This page uses Romanovsky and specifies the actual bets rather than relying on the name alone.

Where do I place the chips?

For the displayed preset, place three units on each of the first two dozens, one unit on the 25/26/28/29 corner and one unit on the 32/33/35/36 corner.

Which numbers are not covered?

The European preset leaves 0, 27, 30, 31 and 34 uncovered. American roulette also leaves 00 uncovered. Different placements can change the list.

What is the Romanovsky win rate?

In this European +1/-8 preset, a covered and profitable individual spin has a probability of 32/37, or 86.49%. This is different from the probability of finishing a session ahead.

How much do I win on a covered number?

The complete layout returns nine units from an eight-unit stake, leaving one unit of net profit. With $1 units, that is a $9 total return and +$1 net profit.

What happens if zero lands?

Zero is uncovered in the displayed preset. All four bets lose, producing an eight-unit loss.

Why can I win most spins and still lose money?

A covered win adds one unit, while an uncovered loss removes eight units. The number of wins must be considered alongside the size of the losses.

Can Romanovsky guarantee a profit?

No. The layout does not remove the house edge, and a high covered-number probability does not guarantee a positive session result.

Is Romanovsky better than Martingale?

They create different betting patterns. Romanovsky spreads a fixed stake across its layout, while Martingale increases an even-money stake after losses. Compare defined rules, exposure and limits rather than assuming one is universally better.

How much bankroll do I need?

Eight units are needed to place one full bet in this preset. That is a placement minimum, not a safe bankroll or a guarantee that the session can continue.

Does Romanovsky work on American roulette?

The bets can be placed in the model, but 00 creates another uncovered outcome. Covered probability falls to 84.21%, and the house edge for these bets rises to 5.26%.

Does the calculator predict the next number?

No. It calculates the result of a defined bet arrangement. The simulator generates example sequences to illustrate possible outcomes.

Is the simulator free, and does it use real money?

The simulator is free and uses play money. It does not accept deposits, place wagers or create a gambling account.

How we calculate and review the results

The calculator uses the four bets shown in the layout table, standard dozen and corner payouts, and equally likely independent outcomes on the selected wheel.

Probabilities are calculated from exact outcome counts and rounded for display. Payout examples use the entire stake placed on a spin so that total return and net result remain distinct.

Simulations illustrate possible sequences. They do not predict a casino session or establish that a strategy will be profitable.
