This is the ultra-mega-hard version of Vegas Solitaire
Not only you can browse the Stock pile only once, but the cards are drawn in groups of three. Only the card on the right can be used. If you manage to move this card to the Tableau/Foundation piles, then the card on the left is activated for use.
The basic Vegas Solitaire game is hard to win. The Vegas Solitaire Turn-Three game is nearly impossible to beat.
The standard Solitaire rules are available on the main page. The additional rules are available on the pages of the particular games
