I'm at a roulette table. I only bet on red. When I lose I triple my bet, when I win I restart. Is this a roulette strategy?
Ok so here's the rules
I just bet on red every time
I start with 1 dollar
every time I lose, I triple my previous bet
every time I win I restart
I'm going to simulate 10 games
Game 1 - Bet $1 Lose
Game 2 - Bet $3 Lose
Game 3 - Bet $9 Win $18
Game 4 - Bet $1 Lose
Game 5 - Bet $3 Lose
Game 6 - Bet $9 Win $18
Game 7 - Bet $1 Lose
Game 8 - Bet $3 Lose
Game 9 - Bet $9 Lose
Game 10 - Bet $18 Win $36
In this simulation I'm losing at a rate of 70%. In reality the lose rate is closer to 52%. I put in $54 but I'm walking away with $72, basically leaving the building with $18.
Another example. Let's pretend I walk in with $100,000 to bet with. I lose my first 10 games and win the 11th.
1 lose
3 lose
9 lose
27 lose
81 lose
243 lose
729 lose
2187 lose
6561 lose
19683 lose
59049 win $118098
$88573 spent out of pocket, $118098 won
Walk out with roughly $29525.
I get most casinos won't let you be that high but it's a pretty extreme example anyway, the likelyhood of losing 10/11 games on 48% odds is really unlikely.
To make things worse, Vegas now have triple 0 roulette tables. Three zeros in a row. In the same place.
Do not play Roulette if you want to win.
The only bet in a casino isn't to the casinos favor is on Craps and it's called ODDS. But to get to able to play it you have to win against 1.41% house edge first. And it is capped about 10x or 5x of original bet.
If you want to have the best odds against a casino that is hard work and not solid strategy. Counting cards can make money but honestly the amount of work it requires - you are better on the stock market or even in crypto.
Do not gamble against the casino.
The only reason to gambe is to have fun and safe risk with money you decided to spend and to never see again.
