Some consider betting strategies such as martingale
Martingale is a strategy to lose!
I remember that there was a guy arguing with a casino a few years back wondering how it's possible for red to come up 12 times in a row, well, tough luck the record is 32 times in a row, so if you would have started with $1 by the last number you would have needed to bet 2,147,483,648. yup that's 2 trillions! Both Martingale and Paroli are a bullet proof way to lose your money!
Do you use one of these for you to take an advantage of the game or you still believe that it is a game of chance and luck?
If we talk about gambling, there is no beating the "system".
I don't play in casinos, so no slots, dice, roulette, I only bet on horses and on what horses and jockeys /stables I know!
There is no bullet proof way of winning, you can lose with a 1.0002 favorite, you could lose 8 times in a row with a favorite (happened Friday) you only make money with a strategy in which you start from the beginning knowing that your going to lose some but you will make up by hedging you bets as much as possible!
You will probably never going to get a 6000:1 odds ticket and if you do get one it will probably because you already slot 8000 of them.
So, the most important thing is betting only on tings you know!
You have a horse that is 11111 (five victories in a row) but that were on polytrack not on grass over different distances and he's back after a 8 months break? You simple stay out of it!
Now if we talk dice or slots or roulette, there is no winning strategy, there are no tips there is nothing, is pure gambling as much as coin tossing while blindfolded.
