From what I understand the game works as 50% chance to win with a proper house edge (I think 5% is still a lot) and not 1 in 3 chance. You do see three cards on the screen but you do not have 1 in 3 card chance, the game mechanics work as in you get %50 chance of winning (so you have 1.5 cards in 3 cards chance to make it clear) and whatever you choose is a flip toss so if what you select comes than you win and the graphics of the game is just for show, not for real results.

It is at least clears up the bad odds (which I still think is a high house edge but not as bad as we assumed) but it still requires a lot more explaining, many people believed there was a 1 in 3 chance to win on a 50% profit without you explaining it, so you have to make it clearer for everyone that plays.
