This is crap. If you play Roulette or something similar, you will lose in the very long run as the edge is with the house.
I agree with you! No gaming machine or casino will work at a loss. In any case, the player will lose money. If it were not so then there were not so many casinos.
A player can be lucky and win against the casino, but if he plays long enough his streak will also end with a loss.
this is the pattern of the gaming business,the casino can never lose, it's naive people can only think that they can get rich playing roulette or blackjack, although some may be able to get a big prize---but such cases happen unfortunately very rarely
the casino never loses.
and the casino makes a profit from those players who lose.
but some win more than lose.
