ok this is potentially foolproof, if you have the money to back you up, its to do with the game of roulette. you start with a bet of $1. you bet Red or black. if you win you start over again at $1. you bet what ever colour you bet last time, stick to that colour! if you lose you double your bet, so now you bet $2. and choose the same colour you picked. if you lose your bet is doubled so you make up the money. the only problem is if you dont have enough money, because when the bet is doubled everytime the money can get to some high stakes, but potentially with enough money this is a foolproof way, unless you are super unlucky and you bet red 15 times and everytime it comes up black. haha.
well if you have enough money to keep going il do a table of it doubling, 1 1 2 2 4 3 8 4 16 5 32 6 64 7 128 8 256 9 512 10 1024 11 2048 12 4096 13 8192 14 16384 15 32768 16 65536 17 131072 18 262144 19 i guess we stop at a quarter of a million pounds so dont fail 19 times
Fail, known method for many years, why do you think all of the roulette have LIMITS on them bets... Its foolproof but casino's and online casino's arent fools lol.
