Use two standard 52-card decks
Deal 10 tableau piles: 4 piles with 6 cards and 6 piles with 5 cards
Turn only the top card of each pile face up
Keep the remaining cards as the stock
Build descending sequences in the same suit
Move cards or groups of cards only if they form a valid descending sequence
Place a card on another card that is one rank higher
Use any suit for moves in easier versions, but same-suit sequences are required to complete a run
When a tableau pile is empty, any card or valid sequence can be placed there
If a tableau pile has a complete sequence from King down to Ace in one suit, remove it from play
When no more moves are available, deal one card face up to each tableau pile from the stock
Do not deal from the stock if any tableau pile is empty
Continue building sequences and dealing new rows until the stock is gone
Win by removing all complete King-to-Ace sequences from the tableau
Use fewer suits for easier play and more suits for harder play
