Masse Égale Roulette Strategy: How Flat Betting Works
Masse Égale is flat betting: the stake stays the same after a win or a loss. It prevents the previous result from automatically changing the next wager, but it does not alter the probability of the next spin or Roulette’s house edge.
The strict version repeats both the same stake and the same selection. Keeping a £2 stake but moving it to a different number is still flat staking, although it is not the strict same-selection form described on this page.
Masse Égale in One Four-Spin Example
The diagram uses a split bet on 17 and 20. The chip remains on the same dividing line and the stake remains £2 on all four spins. Only the result and running session balance change.
| Spin | Winning number | Stake | Spin result | Running result |
|---|---|---|---|---|
| 1 | 8 | £2 on 17/20 | −£2 | −£2 |
| 2 | 31 | £2 on 17/20 | −£2 | −£4 |
| 3 | 20 | £2 on 17/20 | +£34 | +£30 |
| 4 | 12 | £2 on 17/20 | −£2 | +£28 |
Profit and return are different: a winning £2 split pays £34 profit and returns £36 in total because the original £2 stake is also returned. Across all four spins, £8 was staked, £36 came back and the final net result was +£28.

What Masse Égale Actually Means
Masse Égale, often typed as Masse Egale without the accent, is the conventional name for a fixed-stake Roulette method. The frequent spelling “Masse Égalé” is incorrect. The method is simple, but two versions are often mixed together:
Strict Masse Égale
Choose one selection and one stake, then repeat both after every result. For example, place £2 on the 17/20 split on every spin.
General flat staking
Keep the stake amount fixed but allow the selection to change. For example, stake £2 on red, then £2 on odd, then £2 on a dozen. The stake is flat, but the selection is not fixed.
Neither version predicts the next number. The distinction is only about how the bet is organised. For the wider context, see the main Roulette strategy guide.
Prefer a single-zero European or French table over an American double-zero wheel.
Use an inside or outside bet whose placement and payout you understand.
Use the same amount after a win, loss or zero. Do not add a recovery progression.
Track total turnover, gross return and the final net result, not only winning spins.
A stop point is not part of the maths: a spending or time limit can control how long the session lasts, but a stop-win or stop-loss does not improve the expected return of the next spin.
Why One Straight-Up Win in 37 Spins Can Still Lose
A straight-up bet pays 35:1. That means a winning £2 spin makes £70 profit and returns £72 in total. It does not mean one winner automatically covers 37 separate £2 bets.
The distinction matters because isolated winning-spin profit and complete-session profit are not the same figure. In this example, the winning spin makes £70, but the other 36 stakes have also been placed.
Long-run check: £74 of standard European Roulette turnover has a theoretical expected loss of £2 because £74 × 2.70% is £2. The actual 37-spin result can be much higher or lower. The figure is an average over repeated play, not a forecast for one session.
The probability of receiving no straight-up hit at all across 37 spins is about 36.29%. Use the Roulette odds calculator and payout guide for broader single-spin and multi-spin probabilities.
Masse Égale Session Calculator
Enter the wheel, fixed bet, stake, number of spins and actual wins. The calculator shows total turnover, gross amount returned, the complete session result, expected hits, no-hit probability, theoretical expected loss and the number of wins required to break even.
It models one standard non-overlapping bet on every spin. It deliberately keeps winning-spin profit separate from the final result so that a large payout is not mistaken for a profitable session.

Which Fixed Bet Should You Use?
Masse Égale can be applied to inside or outside bets. Changing the bet type changes coverage, hit frequency, payout and normal session swings. On the same standard European wheel, it does not change the usual 2.70% house edge.
| Fixed bet | Pockets covered | Payout | European hit chance | Profit on one £2 win | Expected hits in 37 spins | Wins needed to break even | Typical swings |
|---|---|---|---|---|---|---|---|
| Straight-up | 1 | 35:1 | 2.70% | £70 | 1 | 2 | Highest |
| Split | 2 | 17:1 | 5.41% | £34 | 2 | 3 | Very high |
| Street | 3 | 11:1 | 8.11% | £22 | 3 | 4 | High |
| Corner | 4 | 8:1 | 10.81% | £16 | 4 | 5 | High |
| Six-line | 6 | 5:1 | 16.22% | £10 | 6 | 7 | Medium to high |
| Dozen or column | 12 | 2:1 | 32.43% | £4 | 12 | 13 | Medium |
| Even-money | 18 | 1:1 | 48.65% | £2 | 18 | 19 | Lower |
Expected hits are not promised hits. They are the average count produced by the probability over many equivalent samples. One 37-spin session can contain no straight-up win, several straight-up wins or anything in between.
Higher hit frequency is not better value: an even-money bet lands more often than a straight-up number, but it pays less. Standard inside and outside bets on the same European wheel normally retain the same house edge.
Masse Égale Versus Progression Systems
The clearest benefit of flat staking is measurable: the next stake does not increase because the previous bet lost. That prevents progression-related stake growth, but it does not prevent ordinary Roulette losses.
| System with £2 base | After a loss | After a win | Five-loss stake sequence | Total exposed after five losses | Next stake |
|---|---|---|---|---|---|
| Masse Égale | Stay at £2 | Stay at £2 | £2, £2, £2, £2, £2 | £10 | £2 |
| Martingale | Double | Reset | £2, £4, £8, £16, £32 | £62 | £64 |
| D’Alembert | Add one £2 unit | Remove one £2 unit | £2, £4, £6, £8, £10 | £30 | £12 |
| Paroli or Reverse Martingale | Reset to £2 | Increase | £2, £2, £2, £2, £2 | £10 | £2 after losses |
Paroli looks flat in a five-loss example because it increases after wins rather than losses. Its table-limit pressure appears during a winning progression. Masse Égale has no progression-related table-limit pressure as long as the chosen fixed stake already fits within the table range.
Fixed exposure still carries loss risk: five £2 losses cost £10, twenty-five cost £50 and fifty cost £100. The stake does not grow, but total turnover and cumulative losses can still grow with the number of spins.
European, French or American Roulette?
The staking rule works on any wheel, but the wheel changes the underlying probability and expected return. The Roulette wheel and table guide shows the pocket and betting-layout differences.
| Wheel | Pockets | Zeros | Standard house edge | Flat-staking note |
|---|---|---|---|---|
| European Roulette | 37 | 0 | 2.70% | Lower standard edge than American Roulette. |
| French Roulette | 37 | 0 | 2.70% normally | La Partage can reduce the edge to 1.35% on qualifying even-money bets. |
| American Roulette | 38 | 0 and 00 | 5.26% | The extra 00 lowers the hit probability of every ordinary fixed bet. |
French-rule point: La Partage applies only to qualifying even-money wagers when zero lands. It does not improve a fixed straight-up, split, street, corner, six-line, dozen or column bet.
What Masse Égale Does and Does Not Do
What it does
- Keeps the amount exposed on each spin predictable.
- Removes loss-driven stake escalation.
- Requires no progression sequence or recovery calculation.
- Works with inside or outside bets.
- Makes turnover straightforward to calculate.
What it does not do
- Change the house edge or RTP.
- Predict the next result or make a number due.
- Recover earlier losses automatically.
- Prevent a long sequence of losing spins.
- Make a larger session budget mathematically safer.
Masse Égale is best understood as a clear staking format, not a winning system. It is easier to audit than a progression because the stake is fixed, yet the final outcome still depends on random results and the chosen wheel’s house edge.
How This Guide Was Checked
Placement and payout checks
The 17/20 diagram was built against a standard European betting layout. A £2 split win pays £34 profit and returns £36 in total. The four-spin ledger was then checked from the complete £8 turnover.
Probability and calculator checks
European calculations use 37 pockets and American calculations use 38. Hit probability is covered pockets divided by total pockets. Expected loss uses 2.70% for European or standard French Roulette and 5.26% for American Roulette.
The calculator assumes one ordinary, non-overlapping fixed bet on each spin. It separates gross return from net result and does not model En Prison or La Partage settlements.

Responsible Gambling and UK Support
A fixed stake prevents automatic escalation, but it does not prevent losses or make a longer session safe. Set a spending and time limit before playing, and do not increase the stake to recover an earlier result.

Masse Égale Roulette FAQs
What is the Masse Égale Roulette strategy?
Masse Égale is a flat-staking method. The player chooses a fixed stake and repeats it after every win and loss. In the strict version, the same selection is repeated as well.
Is Masse Égale the same as flat betting?
Masse Égale is the clearest named form of flat betting. General flat staking requires only the amount to remain fixed, while strict Masse Égale normally keeps both the amount and selection unchanged.
Is it spelled Masse Egale, Masse Égale or Masse Égalé?
Masse Égale is the correct accented spelling. Masse Egale is the normal unaccented search and keyboard version. Masse Égalé is a common misspelling.
Must I repeat the same number or only the same stake?
For strict Masse Égale, repeat the same stake on the same selection. Moving the fixed stake to another number remains flat betting, but it is not the strict same-selection version.
Can Masse Égale be used on red or black?
Yes. It can be used on red, black, odd, even, low or high by repeating the same fixed amount. On standard European Roulette, the selected even-money bet wins on 18 of 37 pockets and loses when zero or the opposite result lands.
Does flat betting change the Roulette house edge?
No. It changes stake behaviour, not the probability or payout of the bet. Standard European inside and outside bets normally retain a 2.70% edge, while standard American bets normally retain 5.26%.
Why can one straight-up win in 37 spins still leave a loss?
Thirty-seven £2 bets cost £74. One straight-up winner returns £72 in total, including the winning £2 stake. If the other 36 spins lose, the complete result is therefore −£2.
What is the difference between Masse Égale and Martingale?
Masse Égale leaves the next stake unchanged. Martingale doubles after a loss. With a £2 base, five losses expose £10 under Masse Égale and £62 under Martingale, with £64 required for the next Martingale stake.
Does a stop-win improve Masse Égale?
No. A stop-win can end a session at a chosen point, but it does not change the expected return or make the next spin more favourable. A spending or time limit is still useful for controlling the scope of play.
Which Roulette wheel is better for flat betting?
A single-zero European wheel has a lower standard house edge than an American double-zero wheel. French Roulette can be lower again on qualifying even-money bets when La Partage applies.
