Colours Solitaire uses one deck (52 cards). It is a variation of Lady Betty. You have 6 tableau piles and four foundations. Four base cards (a two, a three, a four and a five of alternating colors) are moved to the foundations as they become available.
The object of the game
To build the foundations up in color to (black on black, red on red), wrapping from King to Ace, until each pile contains 13 cards.
You can move cards from the stock to the foundations and tableau piles. There are no restrictions on placing cards from the stock pile onto the tableau piles. Only the top card of each pile is available for play on the foundations. You cannot move cards from pile to pile.
There is no redeal. The skill in this game is to decide which tableau pile to put each card on. You shouldn't block lower cards by higher ones of the same color.
