I know someone who does 1-2-3-4-5-6 on some lotteries here as well. Sometimes that is a good way to make some money if you are lucky enough and if you are not lucky enough then you will not be making any profit at all.
I cannot say that there is anything you should do this is why I have to say that there is a good chance we could test this out for a longer term and you may end up with a lot of profit or you may end up with nothing at all and you will be able to tell us if it really works. After all 600x is not really a bad return at all, depending on how many takes you had to do that is a very good return if you ask me.
Plus, if it is that much important for some people to test this out, they could do 600 bets and there is a good chance you could get at least one, it is not about not getting any at all, if you want to then there is a quite easy way to do it, have a few thousand bets and it is "almost" guaranteed to hit at least once.
The 600x are not the only multiplier.
With this pattern you have 5x, 20x, 270x, 600x and 900x as possible hits.
Compared to other games, however, you can also make more all-time wager well here without making much loss.
Which in turn is good for your own bonuses.
But you should always remember that it is gambling and in the end the bank always wins anyway.
And that's because after a win, people usually don't stop playing.
