I want to know how the game providers are work and in which aspects they are involved...

Is this game providers involve in player wining and losses matter

If as a player I won huge amount if the casino was not worthy to pay that amount then game providers will handle this...

Hello, if I understand correctly, you think that game providers affect your winnings directly. Therefore they should pay you in case you win and the casino doesn't want to pay, am I right?

Yes..

What makes you think such a thing, please?

Hi, take a look at this article and especially the video: http://www.kpvfaw.com/how-slot-machines-work-math

When you play in a casino, all the spins and results are sent to game providers servers. So the decision whether you win or lose is done on the provider's server.

Then the information about the result of your spin is sent to the casino where you play. The casino either deducts funds from your casino account (in case you lose) or they add funds (in case they receive information about your winnings).
