Lucky number method:
This method can work on any type of European roulette table (online/offline) but would probably work best on a live table instead of a computer generated one.
We know that the odds of getting a single number is 37-1 but with with a payout of 36 times your bet (the house edge)
Well this method isn't so much a cheat or a way to swing odds in your favour but more of a basic strategy of play.
Lets say you have about £40-50 SPARE cash to burn using this method.
There's 2 ways to play. Observe the last 20 or so spins (you can do less if you wish but no less than 10) and then;
A) CHoose a number that hasn't shown and bet every spin until it hits your number as statistically it should be due
B) Choose one of the hot numbers that have shown 2-3 times in the last ~20 spins as there may be a bias.
The idea is based on your odds, within every 37 spins (in theory) a number should come up at least once. We say in theory because we know this doesn't always happen.
If on your 36th-37th SPin your number comes up, you will have made all your initial bets back and you can either start again or retire for the night.
I recommend if your win comes early, i.e. within the first 10 spins, pocket it and that's it, don't get too overambitious.
Same goes for a losing streak, cut your losses maybe give yourself a few more spins over the recommended 37 which is why I recommended a budget of £40-50 @ at £1 per bet.
If you can afford to do £10 per bet then your payouts will be nice enough for you not to worry about continuing play but be aware you will be risking at around £400 if it goes wrong!
