How to calculate double bet chance game probability?

Hi again

I'm having trouble figuring out how to calculate slot games with double bet chance games. for example, Fruit Cocktail game has a feature, that after each win, you have the option to start double bet game. 5 cards appear where only the first one is open. Then you have to choose from 4 closed cards and if the one you pick up beats the first one, then your win is doubled and so on until you stop or lose (all the win, line + double bet).

Ok enough theory, now my problem. Even if I come up with double bet game pay probability, I still don't know how many times the user will start double bet chance game, because it's optional and therefore can't calculate total pay probability for a game. Anyone had similar issue? any hint, direction, advice would be greatly appreciated.

Many thanks in advance.

Always make double up games with a 50/50 chance of winning. This way, it does not affect the return of the game; it only increases the volatility.

As for not knowing how far a player will go, you should enforce a limit which will reduce your exposure. The limit could be that you may only double up until you reach a certain number of credits, or you can limit the number of double ups.

Thanks CrystalMath. Even if I make double up games 50/50 chance of winning, in case the user loses, he's also losing the credits won in line play, so this does affect the return of the game..? or it doesn't? :)))
I'm really sorry for so much probably obvious questions, this is my first slot game development trial :)

Thank you again very much
I really appreciate your help

EDIT: I think I get it. Once he loses X amount of credits, next he wins X amount of credits and win/loss cancels each other out? That's the idea right?
