The aim of Congress Solitaire is to build all four suits up from ace to king using two decks of 52 playing cards each.
Player is dealt 8 cards into two piles forming the tableau, 4 cards in each pile.
Remaining cards are set aside to form the stock pile.
Cards from the stock pile is dealt one at a time to the waste pile with no re-deal.
Cards on the tableau can be built down regardless of suit and any gap is filled by any top card from the waste pile.
Foundations are built up by suit from Ace to King.
When the player gets stuck he can click on the stock file. This will deal one card at a time onto the waste pile. The player may move the top card from the waste pile into the tableau or to the foundations to continue.
