Solitaire 64

Klondike solitaire: twenty-eight cards are dealt into seven piles, the last card of each face up, and the rest stay in the deck. On the piles, a card goes on one a rank higher of the other colour, a face-up card carries its whole run with it, and only a king can fill an empty pile. At the top, build the four suits up from ace to king. In Regular play the deck turns three cards at a time with unlimited passes. In Las Vegas play it turns one card at a time for a single pass: the deck costs $50 and each card sent up pays $5, so you finish with a profit or a loss. When the deck is used up and every card is face up, the game finishes itself and you win.

Controls: The stick moves the cursor between cards (up from the piles reaches the deck and the ace piles). The left button turns the deck, picks up a card or run and puts it down; the right button sends a card straight up to its ace pile or puts back the cards in hand. Press both buttons to concede. Either controller works.
