top card from the wastepile. You may only go through the stock once. The object of the game is to move all the cards to the foundations to form families built up from ace to king. Variants Napoleon at St Helena forms the basis for several variant games, most of which make it easier to win. Common variations are: dealing the aces to the foundations at the start of the game, building the tableau down by alternating colour rather than by suit, and allowing cards built down on top of a tableau to be moved, as a sequence, together.
