    The Hollandish Betting system is an example of a negative progression system like the Martingale or D’Alembert, which means you increase your bets size after you make a loss.

    This method is an example of a negative progression system like the Martingale or D’Alembert, which means you increase your bets size after you make a loss. However, there are lots of differences, too.

    How to use the Hollandish Betting System


    The first thing you need to know about this intriguing system is that the progression it uses depends on how big your initial bet is. Assuming you bet £1 to start with it looks as follows: 1,3,5,7,9

    For larger initial bets, simply double it. A starting bet of £2 would give you 2,6,10,14,18

    Like other negative progression systems, when you make a profitable bet you simply go back to the beginning again, so you won’t be gambling with large amounts of your winnings. 

    This is how other negative progression system do work, but the big difference here is that you play each stage of the Hollandish system three times.


    To determine whether you’re ahead or not at any stage you’ll look at the outcomes of those three wagers and if two or three of them were wins then it’s classed as an overall win and you go back to the proverbial Square One and the beginning of the progression.

    This has the advantage of preventing your bets rapidly escalating – a common criticism of other negative progression systems, especially the Martingale which can rapidly spiral out of control and result in you losing your entire bankroll or breaking the casino’s betting limits.

    The Hollandish is best explained by illustration:

    1. Suppose you start with a bankroll of £20 and bet £1 as your initial wager
    2. You’ll therefore be working with the 1,3,5,7,9 progression.
    3. You lose, and therefore bet £1 again
    4. You lose again: That 2 out of 3 lost
    5. You now win again, so your bankroll totals £19
    6. You’ve therefore lost the majority of your round of three bets and have to move up a notch:
    7. You now bet £3 and win, taking your bankroll to £22
    8. You bet again and win again, taking you up to £25
    9. You bet the final £3 and lose, taking you down to £22
    10. With two out of three wins it’s time to go back to the beginning with £2 in profit.

    Like the Martingale, D’Alembert, Fibonacciand Labouchere systems this idea works with even bets, otherwise known as outside bets. These are 50/50 propositions like red or black, odd or even etc. 

    Whilst other negative progression system can be adapted to accommodate dozen bets and other relatively low odds inside bets, the Hollandish cannot as you’ll find it too difficult to win each three-spin stage and will consequently find yourself betting more and more each time with no chance of taking any profit and starting again.

    Why the Hollandish Works


    One huge advantage of this system is that you don’t need more wins than losses to make a profit in one round. However, like any system you may find yourself in a position that requires you to make several wins in a row to get you back to your starting bankroll level, which you may find difficult to achieve.

    If you want to make you bankroll last, then you will find this system works pretty well; it’s also fairly risk-averse, so if you’re a fairly conservative player it should suit you. 

    Budgeting with the Hollandish


    Like any betting system, it’s advisable to set limits for yourself: A recommended, intuitively sensible approach is to stop when you find that you’ve lost 50% of your bankroll, and also stop when you’ve won 50%. 

    That way, you’re guaranteed to walk away from the table without having your pockets emptied completely, and with this system it’s likely that even with a run of bad luck you’ll get planet of spins in so you can enjoy a good session even if things don’t ultimately go your way.

    As with any system you can amend the Hollandish System to suit your own preferences if you wish: For example, if you want to make each stage a best of five rather than a best of three then you’re more than entitled to do so. 


    As with any system you’re advised to find a casino that’ll let you play in demo mode, so you’ll have some idea of what you’re letting yourself in for before you actually start placing bets for real.
