Win-after-up stake system
The Ascot Roulette System: How the Stake Ladder Works
The Ascot roulette system uses a written ladder of stake sizes on one even-money bet. Start in the middle, move one step higher after a win and one step lower after a loss.
Published versions use different ladders. This guide uses 2, 3, 5, 8, 13, 20 and 30 units, starts at 8 units and ends the cycle after a win at 30 units or a loss at 2 units. The method changes stake size only; it does not change the wheel odds.
Worked version: one fixed even-money bet | 2-3-5-8-13-20-30 ladder | start at 8u | win moves up | loss moves down.

The values below are the size of the next stake. They are not roulette numbers. Use one even-money selection, such as Red, and keep that same selection for the complete cycle.
Check the wheel and stake range first
Ascot starts in the middle of the ladder, so the opening stake may already be several times the table minimum.

The exact Ascot rules used here
There is no single universally agreed ladder. The rules below keep every calculation and example on this page consistent.
Use Red/Black, Odd/Even or High/Low. Keep the same selection through the cycle.
The chosen ladder is 2-3-5-8-13-20-30, so the first stake is 8 units.
A win moves one position higher. A loss moves one position lower.
Finish or reset after a win at 30u or a loss at 2u.
Why one win and one loss can still leave a loss
Ascot moves the stake after every result. Because the two stakes are different, an equal number of wins and losses does not mean the money result is even.
Start at 8u, win and move to 13u. Lose the 13u bet and return to 8u.
Start at 8u, lose and move to 5u. Win the 5u bet and return to 8u.
A five-spin example
The running total can move quickly even though the stake always follows the written ladder.
| Spin | Stake and result | Running total | Next stake |
|---|---|---|---|
| 1 | 8u win | +8u | 13u |
| 2 | 13u win | +21u | 20u |
| 3 | 20u loss | +1u | 13u |
| 4 | 13u win | +14u | 20u |
| 5 | 20u loss | −6u | 13u |
Try the Ascot ladder
Set the cash value of one unit, then press Win or Loss after each test spin. The tool moves the next stake and keeps a running result. It starts at the 8-unit middle position.
Win/Loss sequence tester
Keep the unit value fixed for the cycle. Press Reset to start again at 8 units.
Start with 8 units. A win moves the next stake to 13 units; a loss moves it to 5 units.

The top stake does not cap the total loss
A written ladder limits the size of one wager, but the player can move between the same positions repeatedly. Cumulative losses can therefore keep growing even when no single stake exceeds 30 units.
What the ladder costs in cash
This table converts the fixed values into cash. It is not a bankroll recommendation.
| One unit | First stake: 8u | Lowest: 2u | Highest: 30u |
|---|---|---|---|
| £0.10 | £0.80 | £0.20 | £3.00 |
| £0.20 | £1.60 | £0.40 | £6.00 |
| £0.50 | £4.00 | £1.00 | £15.00 |
| £1.00 | £8.00 | £2.00 | £30.00 |
On standard European roulette, the theoretical average loss is 2.70% of whatever is staked. An 8-unit bet therefore has an expected loss of about 0.216 units, while a 30-unit bet has an expected loss of about 0.811 units. The percentage is unchanged; only the amount exposed is different.
European, French or American roulette?
Ascot is normally used on an even-money roulette bet. The wheel and zero rule therefore matter more than the name of the progression.
| Wheel | Win chance | When zero lands | House edge |
|---|---|---|---|
| European | 18/37 48.65% | Full stake loses | 2.70% |
| French with La Partage | 18/37 48.65% | Half of a qualifying even-money stake is returned | 1.35% |
| American | 18/38 47.37% | 0 and 00 both lose | 5.26% |

La Partage only helps when the displayed table rule applies to the chosen even-money wager. The stake ladder itself does not reduce the edge.
How Ascot differs from other progressions
Ascot is closest to other systems that increase after a win. It should not be described as automatically safer simply because it reduces the stake after a loss.
Uses a chosen ladder. Move one position higher after a win and one lower after a loss.
Usually increases by one unit after a win and decreases by one after a loss, rather than using a custom ladder.
Doubles after a loss and resets after a win. Its stake pressure rises during losing runs instead of winning runs.
Ascot avoids unrestricted doubling, but that does not make it safe or profitable. The order of wins and losses, the chosen ladder and the cash value of one unit all affect the session result. The underlying roulette odds stay the same.

Ascot roulette system FAQs
What is the Ascot roulette system?
It is a stake-ladder system for one even-money bet. The player starts in the middle of a written sequence, moves one step higher after a win and one step lower after a loss.
Where do I start in the Ascot sequence?
Start at the middle value. In the 2-3-5-8-13-20-30 example used here, the first stake is 8 units.
Are 2, 3, 5, 8, 13, 20 and 30 roulette numbers?
No. They are stake sizes. Place the current amount on one even-money selection such as Red, Black, Odd, Even, High or Low.
What happens at the top and bottom of the ladder?
This guide ends the cycle after a win at 30 units or a loss at 2 units. You can then stop or reset to the 8-unit middle stake.
Does one win and one loss break even?
Not necessarily. Starting at 8 units, a win followed by a 13-unit loss leaves a 5-unit loss. A loss followed by a 5-unit win leaves a 3-unit loss.
Does Ascot beat the house edge or make roulette safe?
No. It changes the stake path but not the odds or payouts. Standard European roulette retains a 2.70% house edge on even-money bets. Ascot avoids loss-side doubling, but cumulative losses can still grow.
Use the ladder as a record, not a reason to chase
Choose the cash value of one unit before starting and check what the 30-unit top stake means in real money. Do not increase the unit value during a cycle to recover losses. The clearest way to learn the movement is to use the tester above or practise on a free roulette game first.
