Forty Thieves

• The tableau builds down in suit, not in alternating colours. A black Nine only ever accepts the Eight of its own suit — a quarter as many options as Klondike.
• There is one pass through the stock. Cards you skip are gone.
• Eight foundations need 104 cards, and the tableau starts with only 40 of them on the table.
• Empty columns are the only staging area, and every card you park there is a card not doing anything else.

It is the reason the game has a reputation. If you want the same two-deck scale with far more movement, play spider solitaire instead.

Classically, no — one card at a time, and any 'sequence move' is really several single moves using empty columns as scratch space. The board here does the bookkeeping for you: a suited descending run can be dragged as a unit, but only up to empty columns + 1 cards, which is exactly what you could have achieved by hand. With no empty column you move one card, with two empty columns you move three.

• Empty a column early and defend it. It is your only flexibility, and it is worth more than any single card.
• Do not bury an Ace. With eight foundations to feed, an Ace stuck under three cards in a one-pass game is often fatal.
• Work the stock slowly. Every card you turn must find a home immediately or it sits on the waste blocking the next one.
• Prefer a move that unblocks a low card over one that builds a pretty sequence.

The forty cards of the opening tableau — ten columns of four — are the 'thieves'. The game is also recorded as Napoleon at St Helena, from the story that Napoleon played it during his exile, and as Big Forty or Roosevelt at San Juan. It has been in English patience books since at least the 1890s.
