Welcome to WoV, just to let you know, there is a, "No profanity," rule on this forum. I'm not an Administrator, but I figured one of them would give you a soft warning for this anyway.

Romacircus, welcome to the forum.

Here's your soft warning about the no-profanity rule from an administrator.

Watch your language, please. This is a classy establishment, most of the time.

for sure though my maths is right?

Actually, no. If you bet a single number 24 times, there is only a 48% chance you will win. You need to bet it 37 times in order to have a 64% chance of a win.

And before you start thinking, "If I have a 48% chance of winning a bet that pays 35-1 and I would only lose 24 if all 24 bets lose, then I should come out ahead, right?", remember that if you win on the 24th bet, you only end up "winning" 12; the 35 you won on the 24th bet minus the 23 you lost on the first 23 bets combined.

ThatDonGuy,
Thank you. However, I have to say that I find your maths and explanation a little hard to follow. So, Romacircus might struggle too.

how would he have any more of a chance then .027 because every roll is independent? hes betting one unit at a time on one number and all of those tries together mean nothing i thought?

Yes, every roll is independent and has a 1/37 chance of happening, but where you say "all of those tries together mean nothing" you are only partly correct (see below).

"You are correct": In that the number of tries mean nothing to the house edge of the game, this will always be the same (assuming an unbiased wheel).
",,, incorrect": The greater the number of tries you make/spins you bet on, the greater the overall chance you have of hitting on at least one of those bets***.

***: It doesn't matter if you bet on 24 spins in a row on the same number, or change the number you bet on after each spin for 24 bets, or even if you bet once a year for 24 years on any single number, it will still be ~52% chance of not hitting (~48% chance of hitting at least once) .
