£150 Roulette Strategy: How the 34-Number Layout Works

The £150 Roulette Strategy places £50 on two dozens and £5 on ten numbers in the remaining dozen. On a standard European table, 24 pockets return the full £150 stake, ten produce a £30 profit, and three lose the complete layout.

It covers 34 of 37 pockets, but the often-quoted 91.89% figure is not a profit rate. Most covered results simply break even, and the standard 2.70% European house edge remains.

How to Place the £150 Roulette Strategy

The layout uses 30 equal units. With a £5 unit, ten units go on each of two dozen bets and one unit goes on each of ten straight-up numbers in the remaining dozen.

1. Stake £50 on 1st 12

This covers numbers 1 to 12 with one ten-unit dozen bet.

2. Stake £50 on 2nd 12

This covers numbers 13 to 24 with the second ten-unit dozen bet.

3. Stake £5 on ten numbers

The example uses 25 to 34, leaving 0, 35 and 36 uncovered.

The diagram uses 25 to 34 for the ten straight-up bets. Choosing different ten numbers from the third dozen changes which two numbers are uncovered, but it does not improve the probability.

The number choice is not predictive. Numbers 25 to 34 are used because they are easy to display. Any selection of ten distinct numbers from the remaining dozen produces the same one-spin probabilities.

Check a Standard European Roulette Table

Before placing twelve separate wagers, confirm that the game uses one zero, pays 35:1 on a normal straight-up bet, accepts the required chip value, and allows the full £150 layout within its table limits.

Open the roulette lobby and check the current chip values, game rules and table limits before staking.

£150 Strategy Odds, Returns and Net Results

The result depends on which type of pocket lands. The gross return includes the winning stake being returned. The net result compares that return with the full £150 placed across all twelve bets.

Swipe sideways to compare the full table.

Pocket type Pockets Probability Gross return Net result
1 to 24 24 64.86% £150 £0, break even
Selected 25 to 34 10 27.03% £180 +£30 profit
0, 35 or 36 3 8.11% £0 -£150 loss

Why 91.89% is not the win rate

The 34 covered pockets combine two very different results. Ten pockets make £30, while 24 merely return the amount staked. The chance of making a profit is therefore 10 in 37, or 27.03%. The 91.89% figure is only the chance of avoiding a net loss on one spin.

Expected result = ((24 x £0) + (10 x £30) + (3 x -£150)) / 37 = -£4.05 per £150 spin

That expected loss is 2.70% of the total stake, matching the standard European roulette house edge. Covering more pockets changes the distribution of results, not the long-run value of the bets.

One selected straight-up result adds £30. One uncovered result loses £150, so five £30 profit results are required to offset one full loss. They do not need to occur consecutively, and break-even results leave the running balance unchanged.

Scale the Strategy to a Different Chip Value

The £150 name comes from using a £5 unit. The same layout can be written as 30 units: ten units on each dozen and one unit on each of ten straight-up numbers.

Each dozen receives 10 units. The ten straight-up bets use another 10 units in total.

One selected straight-up number £180.00 +£30.00 27.03%
An uncovered pocket £0.00 -£150.00 8.11%

Formula: total stake = 30 x unit. Selected-number profit = 6 x unit. Expected loss = total stake / 37.

Common lower-stake versions

These examples only work when the table accepts the stated chip value on every individual straight-up bet.

50p£5£5 total£15
£1£10£10 total£30
£5£50£50 total£150

The same 30-unit layout is sometimes called the $150 roulette strategy when a $5 unit is used. The currency changes, but the probabilities do not.

What Happens Over Repeated Spins?

An 8.11% full-loss probability can look small in isolation. Repeating the layout gives that result more opportunities to appear. The table below shows the chance of encountering at least one uncovered result within a fixed number of spins.

Spins At least one full loss Theoretical average loss
1057.07%-£40.54
2081.57%-£81.08
5098.54%-£202.70
10099.98%-£405.41

The first percentage is calculated as 1 – (34/37)spins. It is not the probability that the complete session finishes behind. The average-loss column is expected value, not a prediction of the result of one session.

Two full-loss results on two specified consecutive spins have a probability of 0.66%, calculated as (3/37) x (3/37). Across a longer run, however, there are many possible pairs of consecutive spins.

What a bankroll figure actually tells you

A larger balance does not change the wheel probabilities. It only funds more complete £150 layouts before any returns are considered.

Available amount Complete £150 layouts
£3002
£6004
£7505
£1,50010

There is no mathematically correct bankroll recommendation for this system. The practical question is whether the full per-spin stake is an amount you are prepared to lose.

£150 Strategy Versus the 24+8 System

The £150 layout is best understood as a 30-unit version of a modified 24+8 system. Two dozens cover 24 numbers, and ten straight-up bets extend the coverage to 34 pockets. That makes it a 24+10 layout in literal terms.

The original 24+8 version covers only eight numbers in the remaining dozen. With ten units on each dozen and one unit on each selected number, it stakes 28 units rather than 30.

Swipe sideways to compare both layouts.

Feature £150 strategy / 24+10 Original 24+8
Straight-up numbers108
Total units3028
Covered pockets3432
Dozen result£0 net+2 units
Selected-number result+6 units+8 units
Full-loss pockets35

Neither version changes the underlying house edge on a standard single-zero wheel. They simply arrange the stake and result sizes differently. See the separate 24+8 roulette strategy guide for the original layout.

Which Roulette Games Preserve These Payouts?

  • Standard European Roulette One zero and normal 2:1 dozen and 35:1 straight-up payouts produce the exact £0, +£30 and -£150 results shown above.
  • Standard French Roulette The same single-zero maths applies when the normal paytable is used. La Partage does not protect dozen or straight-up bets because it applies to qualifying even-money wagers.
  • Standard American Roulette The extra 00 creates four uncovered pockets in this example: 0, 00, 35 and 36. The full-loss probability rises to 10.53%, and the house edge is 5.26%.
  • Lightning and multiplier variants Do not reuse the fixed return table without checking the game rules. Altered straight-up payouts and random multipliers can change the result when a selected number lands.

For the cleanest comparison, use a normal European Roulette paytable. Read the American Roulette guide before applying the layout to a double-zero wheel.

Practical Limits Before You Place the Layout

Twelve positions take time

The system uses two dozen bets and ten individual number bets. On a live table, place them before the betting timer closes. A repeat-bet control can help on later spins, but it is not available in every game.

Check the minimum on each position

A table displaying a low overall minimum may still require a larger chip on each straight-up number. Confirm the individual minimum before assuming that a £3, £15 or £30 version is possible.

Check total and inside-bet limits

The complete layout must fit beneath the table’s total maximum and any separate inside-bet cap. A progression is not part of the strategy, so the stake should remain flat unless you deliberately choose a different unit before a spin.

Ignore unrelated bonus headlines

Table play may be excluded from a casino bonus or contribute little or nothing towards wagering. Choose a table by its rules, limits and usability, not by a slot-led promotion.

Calculation Method

The figures on this page use exact roulette probabilities rather than a random simulation.

  • Wheel: standard European Roulette with 37 pockets, numbers 1 to 36 plus 0.
  • Payouts: 2:1 on each dozen and 35:1 on each straight-up bet.
  • Unit: £5 in the main worked example.
  • Layout: ten units on 1st 12, ten units on 2nd 12, and one unit on each of ten numbers from 25 to 34.
  • Total stake: 30 units, equal to £150.
  • Uncovered pockets in the example: 0, 35 and 36.
  • Expected value: total European stake multiplied by 1/37, giving an average theoretical loss of £4.05 per £150 spin.

The calculation does not claim that the next spin can be predicted, that a loss is due after a run of covered outcomes, or that a larger bankroll changes the house edge. Learn more in the main roulette odds and payouts guide.

£150 Roulette Strategy FAQs

Why is it called the £150 Roulette Strategy?

The name comes from using a £5 unit across a 30-unit layout. Two dozen bets cost £50 each, while ten £5 straight-up bets cost another £50. A smaller unit creates the same pattern at a lower total stake.

Is 91.89% the strategy’s win rate?

No. It is the combined probability of either making £30 or breaking even on one European spin. Only 10 of 37 pockets, or 27.03%, produce a profit. Another 24 pockets return the full stake without profit.

Which ten numbers should I choose?

Any ten distinct numbers from the dozen not covered by the two outside bets have the same probability. Choosing recent, overdue, hot or cold numbers does not improve the layout.

Can I play a £15 or £30 version?

Yes, if the table accepts the required individual chip values. A 50p unit produces a £15 total stake, while a £1 unit produces a £30 total. Check the per-position minimum before placing the bets.

Is the £150 strategy the same as 24+8?

It is closer to a modified 24+10 layout. Two dozens cover 24 numbers and ten straight-up bets cover another ten. The original 24+8 version uses only eight singles and covers 32 pockets.

Does the strategy work on Lightning Roulette?

The chip pattern can be placed if the table allows it, but the fixed £180 straight-up return may not apply. Multiplier games can alter ordinary straight-up payouts, so check the exact paytable before using this outcome table.

Does covering 34 pockets reduce the house edge?

No. On a standard European wheel, the combined layout still has a 2.70% house edge. It creates frequent break-even outcomes and occasional larger losses, but it does not improve the expected value.
