A key concept when you want to win in the casino is the idea of ‘expected value’.
This is an idea that that casinos use to take money off you and that you can use to take money off the casino. The expected value is the amount that you can expect to win (or lose) each time you bet a certain amount.
‘Expected value’ is therefore your win rate (or the casino’s win rate) for each game you play.
For example, if bet $1, and your expected value is $2 then you will make $1 every time you play. On the other hand if your expected value is 50 cents, then you expect to lose 50 cents every time you play. This is not the sort of game that you would ever wish to play.
The trick is only to play games where you have an expected value that ensures you win!
