I just ran across a note I had when I was playing Blackjack about 40 years ago.
It was regarding gambler's ruin.
I had calculated that I had about a 1% advantage counting cards and playing a bet spread of 1-5 units.
A friend who was into math a little, said that in order to have a 99.5% chance of not losing my total bankroll, I needed 1,000 units.
Remember, that's with a 1% advantage over the casino. I don't know what is needed if you're playing a single zero roulette wheel, but I'm sure it's substantially more.
Bankroll is king.
Remember, "He who has enough money is a Lion!"

A player having 1% advantage can in a game as blackjack play 10000 hands before he can see any result of it. The variance in some games are large, and it takes time to be on a safer side. So a decent bankroll is needed.
We can lose for month and still be plus at the end.
All players who can get a slight advantages, try to keep the variance as low as possible.
If a solo player play against a roulette table, the table can lose a lot due to variance even if they have a 1.3 to 2.7% advantages.
The roulette table keeps the variance down if the table has many players, and may be most bets are placed.
At roulette it is not possible to get a mathematical advantage as in some card games. A large bankroll put the ruin in the future, if we are lucky we die before ::) I've always wondered why so many shoots himself in Monaco after an unsuccessful martingale, they could die richer if they did it before the game. ::)
The only way is die when a head or stop the game forever when we had won. At least play less after a large win.
We should anyhow not use any money in a game we can not effort to lose, that make the question of bankroll difficult.
We can win more in the longer run if we use cents, a way to extend the bankroll units, and effort to risk it. 100 Euro can be 10000 units.
Old Christiaan Huygens did some work on this matter(Exercitationum mathematicarum.)
i understand that we need a bigger bankroll to play the game.
but how big is this big? is there a formula for it?
suppose we are flat betting on a 9 numbers per spin and you will hit on an average of 5 spins and the largest DD encountered is 20 spins.
does it mean that my expected BR is 9x20 = 180u?
Good question, Marvin. How long is a rope? How big is a bankroll?
sam, your one of the oldies but goodies here any idea how big s big? :girl_to:
Vin Diesel is big!
