1 deck. Average. No redeal.
Russian 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. The top card is face up. Then 4 additional cards are dealt, face up, onto each of the six piles on the right. You have 4 foundation piles.
Aces are moved to the foundations as they become available.
The object of the game
To build the foundations up in suit to kings.
You may build tableau piles down in suit. Groups of cards can be moved regardless of any sequence. Any face up card in the tableaus can be moved to further a build. All the cards covering it are moved together as a unit. Empty tableaus may be filled with a King or group of cards headed by a King.
Wins are rare.
