Bavarian Solitaire stretches German patience to ten tableau piles across two decks, and drops the foundations entirely: sort the whole deck into runs right on the tableau.

Thomas Warfield's Bavarian Solitaire is German patience with two extra tableau columns, ten piles instead of eight, still dealt from two decks with no foundations at all. You win by sorting the whole deck into runs on the tableau itself.

Ten tableau piles, one card in each to start, fanned downward. Every card is dealt face-up.
A card can be added to a tableau pile only if it's one rank higher than the pile's current top card, regardless of suit, so the only card that fits on a 5 is a 6, and since the sequence wraps around, you can also play an Ace on a King.
Cards on the tableau that are not covered by another card can be played onto any other tableau pile.
Any card can fill an empty slot in the tableau.
Only one card may be moved at a time, though turning on super moves lets you shift a whole sequence at once whenever there are enough empty tableau columns to do it one card at a time anyway.
There is one waste pile, and the rest of the deck is the stock.
Clicking the stock deals one card to the waste at a time. You get only one pass through the stock.
The top waste card is now available for tableau play.
