The Hollandish Roulette Strategy: UK Master Guide
The Hollandish Strategy is a highly structured, low-volatility betting progression designed to tame the chaos of the roulette wheel. Instead of wildly increasing your bets after every single loss, this system groups your spins into “Blocks of Three.” You only adjust your stake after a block is completed. Perfect for European roulette even-money bets, this expert UK guide breaks down the sequence, the math, and the bankroll requirements.

How to Execute the Hollandish System
The magic of the Hollandish system lies in its pacing. Instead of evaluating your profit or loss after every single spin of the wheel, you evaluate your progress in predefined 3-spin blocks. This flattens out the agonizing variance of standard roulette gameplay.
The Core Betting Rules
- The Sequence: Memorize the standard Hollandish progression: 1, 3, 5, 7, 9, 11.
- Start at Block 1: Select a base unit (e.g., £1). You will bet exactly £1 on an Even-Money space for three consecutive spins.
- Evaluate the Block: After the third spin, count your wins. If you won 2 or 3 spins, the block is a Win. If you won 0 or 1 spin, the block is a Loss.
- If the Block Won: You have secured a net profit. Do not progress. Stay at the 1-unit level for your next 3-spin block.
- If the Block Lost: You must move to the next number in the sequence. Your next 3-spin block will be played betting 3 units per spin. Continue stepping up until you win a block.
A Practical Sequence Example (£1 Base)
- Block 1 (£1 Stakes): You spin 3 times. You get 1 Win and 2 Losses. The block is a Net Loss (-£1). Move to the next sequence step.
- Block 2 (£3 Stakes): You spin 3 times. You get 0 Wins and 3 Losses. The block is a Net Loss (-£9). Move to the next sequence step.
- Block 3 (£5 Stakes): You spin 3 times. You get 2 Wins and 1 Loss. The block is a Net Win (+£5). The sequence is broken, reset your next block back to £1 stakes.

The Mathematical Logic Behind the 1-3-5 Sequence
Why does the Hollandish sequence skip numbers? Why not just bet 1, 2, 3, 4? The answer lies in calculating the net loss of a bad 3-spin block at live roulette tables.
The Block Payout Math
Assuming you are betting 1 unit per spin, here are the four possible outcomes of a 3-spin block:
- 3 Wins: Net Profit +3 Units.
- 2 Wins, 1 Loss: Net Profit +1 Unit.
- 1 Win, 2 Losses: Net Loss -1 Unit.
- 0 Wins, 3 Losses: Net Loss -3 Units.
Why You Must Step Up by 2
As you can see, the worst-case scenario in a block is losing 3 consecutive units. If your sequence only stepped up to 2 units for the next block, winning 2 out of 3 spins would only net you +2 profit, which is not enough to clear the -3 deficit from the previous block. By stepping up to 3 units, a moderate win in the second block will seamlessly clear the deficit of the first block.
Hollandish vs. Other Roulette Systems
How does grouping spins into blocks compare to adjusting your bets after every single spin?
| System Name | When to Escalate Stakes | Progression Aggression | Bankroll Volatility |
|---|---|---|---|
| Hollandish | Only after 3 consecutive spins | Step up by 2 (1, 3, 5, 7) | Low-Medium |
| D’Alembert | Immediately after 1 loss | Step up by 1 (1, 2, 3, 4) | Medium |
| Martingale | Immediately after 1 loss | Double stake (1, 2, 4, 8) | Extreme |
It is absolutely critical to understand that while the Hollandish system makes playing roulette more organized and mathematically interesting, it does not overcome the casino’s house edge. On a single-zero wheel, your Expected Value remains a constant -2.70%. The system slows down your risk exposure, but long streaks of bad blocks will still eventually deplete your bankroll.
