1 deck. Average. No redeal.
Whitehead Solitaire uses one deck (52 cards). You have 7 tableau piles with the number of cards per pile increasing from one to seven from left to right. All cards are face up. You have 4 foundations.
Aces are moved to the foundations as they become available.
The top cards of tableau piles and the waste pile are available to play. You may build tableau piles down by color (red on red, black on black, regardless of suit.). Groups of cards in sequence in the same suit can be moved as a unit from pile to pile. Empty tableaus may be filled by any available card or build.
When you have made all the moves initially available, begin turning over cards from the stock pile. You can move cards from stock pile to the tableau piles and to the foundations according to the rules mentioned above.
There is no redeal.
