Roulette staking system
Hollandish Roulette Strategy: How the 3-Spin Block System Works
The common Hollandish roulette strategy groups even-money bets into blocks of three spins. Keep the same stake for all three spins, move through 1, 3, 5, 7 after a negative block, and return to 1 unit after a positive block.
RouletteUK calculates the common block-reset version. A positive block does not always recover earlier blocks, and other published versions continue until the complete cycle is back in profit.
Three Hollandish blocks, calculated properly
The example below uses a 1-unit base. The third block wins, but the complete sequence remains 5 units down.
Check Roulette Tables and Minimum Stakes
Before choosing a base unit, open the roulette lobby and check the current table minimum, maximum and wheel type.

The exact block-reset rules used on this page
Use one standard Red/Black, Odd/Even or High/Low wager. A European single-zero table keeps the standard edge lower than an American wheel, but the staking system itself does not improve the odds.
-
1
Choose one base unit. One unit is a stake size, not a roulette number. A small table minimum makes the progression easier to cap, which is why the low-stakes roulette guide is useful before playing.
-
2
Place the same stake for three spins. Do not change the amount after spin one or spin two. The block is judged only after the third result.
-
3
Two or three wins make a positive block. The common version resets the next block to the 1-unit base.
-
4
Zero or one win makes a negative block. Move to the next odd-number stake: 1 to 3, 3 to 5, 5 to 7, and so on.
-
5
Choose a maximum level before starting. The ladder has no natural ceiling, so table limits and available money eventually stop it.
The order inside one block does not change its net result because all three wagers use the same stake. For example, W-L-L and L-W-L both finish one stake down.
Why the 1-3-5 ladder does not guarantee recovery
The odd-number ladder can repair some earlier blocks, but not every possible pattern. This is the part that many short explanations miss.

| Block | Stake per spin | Results | Block result | Running result | Common next stake |
|---|---|---|---|---|---|
| 1 | 1u | W, L, L | -1u | -1u | 3u |
| 2 | 3u | L, L, L | -9u | -10u | 5u |
| 3 | 5u | W, W, L | +5u | -5u | Reset to 1u |
Stake cost and worst-case exposure
The ladder rises by two units per negative block. The figures below assume every spin loses, which is the maximum possible loss at each level. A one-win block loses only one stake, not the full three-spin turnover.
The two useful formulas
At a £1 base, reaching block eight means betting £15 on each of its three spins. If every earlier spin and all three block-eight spins lose, the cumulative loss is £192.
The fact that progression is slower than Martingale does not make it low risk. It simply creates a different pattern of stake growth.

| Block | Stake per spin | 3-spin turnover | Maximum block loss | Maximum cumulative loss |
|---|---|---|---|---|
| 1 | 1u | 3u | 3u | 3u |
| 2 | 3u | 9u | 9u | 12u |
| 3 | 5u | 15u | 15u | 27u |
| 4 | 7u | 21u | 21u | 48u |
| 5 | 9u | 27u | 27u | 75u |
| 6 | 11u | 33u | 33u | 108u |
| 7 | 13u | 39u | 39u | 147u |
| 8 | 15u | 45u | 45u | 192u |
Plan the stop before the first block
Do not choose a base unit from a fixed percentage rule. First decide the highest block you are willing and able to reach, then calculate the exposure at that cap. A larger bankroll changes how long the ladder can continue, not the probability of the next spin.
Hollandish block calculator and result tracker
Record each win or loss. The tool keeps all three spins in the same block, then resets to one unit after a positive block or moves up two units after a negative block. It uses the common block-reset rules explained above.
Track a live or practice sequence
Set the cash value of one unit before entering the first result. Use Loss when zero lands on a standard European even-money bet.
Start at 1 unit per spin. Record three results to complete the first block.
Recent results: No results yet.
The tracker does not model La Partage half-losses or the alternative recovery-ledger versions. Practise the sequence first on free roulette rather than using the buttons as a prediction tool.
Three-spin block probabilities
On standard European roulette, an even-money wager wins on 18 pockets and loses on 19 pockets, including zero. That makes a negative Hollandish block slightly more likely than a positive one.
European block outcomes
| Three-spin outcome | Probability | Block result |
|---|---|---|
| 3 wins | 11.51% | +3 stakes |
| 2 wins, 1 loss | 36.46% | +1 stake |
| 1 win, 2 losses | 38.49% | -1 stake |
| 3 losses | 13.54% | -3 stakes |
| Positive block total | 47.97% | Reset to 1u |
| Negative block total | 52.03% | Move up 2u |
Chance of reaching a later block
| Level reached | Stake per spin | Fixed-cycle chance |
|---|---|---|
| Block 2 | 3u | 52.03% |
| Block 3 | 5u | 27.07% |
| Block 4 | 7u | 14.08% |
| Block 5 | 9u | 7.33% |
| Block 6 | 11u | 3.81% |
| Block 7 | 13u | 1.98% |
These are probabilities from one fixed cycle start. They are not the chance of seeing a level somewhere during an unlimited session. See the full roulette odds guide for pocket and bet probabilities.
Why Hollandish rules differ between guides
Hollandish, also called the Dutch roulette strategy, is not described identically everywhere. The three versions below share an odd-number progression, but they do not use the same reset test.
1. Block-reset version
Judge each group of three spins. Two or three wins reset the next block to 1 unit. Zero or one win moves the stake up by two units.
This is the version used in this page, image, tables, FAQs and calculator.
2. Overall-recovery version
A positive block is not enough on its own. Continue the odd-number ladder until the complete sequence returns to profit, then reset.
In the worked example, this version continues from 5 units to 7 units because the sequence remains 5 units down.
3. Recovery-ledger version
Track outstanding losses at each stake level and remain at a higher level until a specified number of recoveries has been completed.
This is more complex than the simple three-spin block system and is not modelled by the calculator.
European, American and La Partage treatment
For a standard European roulette game, zero is a full loss on Red/Black, Odd/Even and High/Low. The positive-block probability is 47.97%, while the negative-block probability is 52.03%.
On American roulette, 0 and 00 both lose. A positive block falls to 46.06% and a negative block rises to 53.94%. More importantly, the standard house edge rises from 2.70% to 5.26%.
When comparing live roulette tables, check the wheel type and minimum stake before applying any progression. The same check matters on automated and real-money roulette tables.
Hollandish compared with other roulette systems
Hollandish delays stake changes until a block ends. Other systems react after each spin, flat bet throughout, or use a different trigger.

| System | Stake trigger | Stake movement | What a win does |
|---|---|---|---|
| Hollandish | After a negative 3-spin block | 1, 3, 5, 7… | Positive block resets in common version, but may leave a sequence loss |
| Masse Égale | No progression | Flat stake | Wins one stake; previous losses remain |
| D’Alembert | After every result | Up 1 after loss, down 1 after win | Reduces the next stake; does not guarantee recovery |
| Fisher | After four consecutive losses | 1, 3, 9, 27… | Any win resets to 1u; complete sequence can remain negative |
| Martingale | After every loss | 1, 2, 4, 8… | A funded win recovers the chain and adds one base unit |
For more progression patterns, compare the Fibonacci system, Labouchere and Contra D’Alembert. None changes the wheel probabilities.
Calculation method and practical limits
What the page calculates
- One fixed even-money selection for all recorded spins.
- Standard full win or full loss settlement.
- Three spins at the same stake in every block.
- A reset to one unit after two or three wins.
- A two-unit increase after zero or one win.
- Running result net of every winning and losing stake.
What it does not calculate
- La Partage half-loss or En Prison continuation.
- The recovery-ledger interpretation.
- Wheel prediction, hot numbers or a change in next-spin probability.
- A guaranteed bankroll requirement, because the odd-number ladder has no final level.
- Casino-specific limits, which must be checked in the current lobby.
Hollandish roulette questions
What is the Hollandish roulette strategy?
It is an even-money staking progression built around three-spin blocks. In the common version, bet the same stake for three spins, reset to one unit after two or three wins, and move from 1 to 3 to 5 to 7 units after zero or one win.
Is Hollandish the same as the Dutch roulette strategy?
The names are commonly used for the same family of odd-number progressions. Rules still vary between block-reset, overall-recovery and ledger-based versions, so the exact reset test matters more than the name.
What does the 1-3-5-7 sequence mean?
Each number is the stake per spin for one complete block. A 5-unit level means three separate 5-unit wagers and 15 units of total block turnover.
What makes a Hollandish block positive or negative?
Two or three wins make the block positive. Zero or one win makes it negative. With ordinary full win and full loss settlement, there is no draw because the block contains three spins.
Does a positive block recover every earlier loss?
No. In the worked example, the first two blocks lose 10 units and the third block wins 5 units. The latest block is positive, but the complete sequence remains 5 units down.
What happens when zero lands?
On standard European roulette, zero is a full loss for Red/Black, Odd/Even and High/Low. Record it as Loss in the calculator. La Partage returns half a qualifying stake and needs a separate rule for any neutral block.
Which Hollandish version does the calculator use?
It uses the common block-reset version: two or three wins reset the next block to one unit, while zero or one win moves the next block up by two units.
Can the Hollandish system beat the roulette house edge?
No. It changes stake timing, not pocket probabilities or payout rules. A standard European even-money stake still carries a 2.70% house edge, and an American one carries 5.26%.
Play limits come before the progression
Hollandish has no natural final stake. Decide a time limit, spending limit and maximum block before beginning, and stop when any one of them is reached. Do not add money to keep an unfinished sequence alive. 18+.
