Casino
Play the thirds. Bet e.g. 5 quid on two of the three thirds (1-12, 13-24,25-36). You get 2-1 plus winning stake back. Therefore, you have a 2/3 chance of going from 10 pounds to 15 pounds.

I trained as a croupier, which means lots of taking turns playing roulette while others dealt, and I found this the only GUARANTEED* winner.

Much simpler to play red or black
50% chance of doubleing your money, and if a roll doesn't come in simply double your bet on the next roll to cover the losses. You literally can't lose.

Hey you two, don't encourage the gullible
Rememer kids, you *will* lose in the long term if you use either of these systems.

Actually it is closer to 49%
there is a bet(0) reserved for the house

a 2/3 chance of going from 10 pounds to 15 pounds
and a 1/3 chance of losing 10 pounds = on average you'll break even (as with every other bet in roulette).

But because you also lose on a 0 (and a 00 if they have them), in the long run you'll lose.

It's better than that for the casino.
You may break even on average, but then you'll hit that run where the ball lands in the third you're not betting on 10's of times in a row, and you lose the lot.

A trained croupier who doesn't understand why there are zeros on a roulette wheel?
You fucking idiot.

I was thinking the same thing
the Zero is specifically there to give the House the edge over everything.

Ive still got 50p chips at home which i won on roullette. All their tables were a minumum £1 bet. (£5 around the edges) meaning it was impossible to use... the house always wins.

the trick is to make a few big bets rather than a lot of small ones
after a lot of repetitions, the average of your results will be very close to the true odds. But on the initial few repetitions, there is a lot of what statisticians call "noise" where the average odds can vary a lot.
For example flip a coin 5 times and it would not be strange to to get one head and 4 tails, or vice versa. Flip a coin 10000 times and it would astronomically strange to get 2000 heads and 8000 tails. The more times you bet, the more your average results will reflect the true odds.
So: bet 3 times on number 12, then walk out win or lose.
