I've been playing a dozen 'hidden' numbers quite succesfully.
On average every number should hit once every 37 spins but it doesn't ! In fact usually around 12 numbers don't hit at all.
I wait for these 12 numbers what I call the 'hidden dozen' and play them.
You can identify these with pen and paper a spreadsheet (search EkbfjoxQYyY on YouTube) or use my program Roulette Key Gold.
These numbers usually turn up in a few spins I play level stakes and get out as soon as I win or break even.
The fact is the longer you play the more likely you are to lose.
But most times I play I'm ahead fairly early on that's when I quit.
I'm not sure I'd be as trusting at online RNG casinos so I try and play live ones where possible.
I
never, ever accept bonuses if you do you'll find it virtually impossible to take your money out.
Of course its still possible to lose so best stick to small stakes, you can play for 10p stakes at some live casinos online.
Hope this helps, its my first time here apologies if I've broken any rules by mentioning my own program but I'm only trying to earn an honest crust! which isn't easy with all the hype and b*****t out there.
