Klondike

Klondike solitaire played for money. Your bank starts at $500. Before each deal you see the face-up cards and place a bet, which is charged once for every card in the deck; every card that reaches its suit pile pays five times the bet back, and getting all 52 home pays a large bonus on top. Seven columns hold one to seven cards with the last face up. The deck is dealt one card at a time onto the stack, in a single pass. A column's whole face-up run moves at once onto a card one higher of the other colour, and only a king goes to an empty column. Cards are played home automatically when it is safe. A bank at or below $0 means BROKE and the game ends.

Controls: Use either joystick. Left and right move the cursor over the seven columns and onto the right-hand panel, where up and down choose the piles, deck or stack. The left button deals from the deck, or picks up and puts down cards. The right button sends a card to its pile. Hold both buttons to end the deal.
