Napoleon at St Helena
2-deck patience or solitaire card game

Napoleon at St Helena is a 2-deck patience or solitaire card game for one player. It is quite difficult to win, and luck-of-the-draw is a significant factor. The emperor Napoleon often played patience during his final exile to the island of St Helena, and this is said to be the version he probably played. Along with its variants, it is one of the most popular two-deck patiences or solitaires. The winning chances have been estimated as 1 in 10 games, with success typically dependent on the player's ability to clear one or more columns. The game is the progenitor of a large family of similar games, mostly with variations designed to make it easier to win, or "get out"
Alternative names include Le Cadran ('The Dial') and, in the US, Forty Thieves, Big Forty and Roosevelt at San Juan.

Why this record matters
The subject matters to the general reference register because the source frames it as 2-deck patience or solitaire card game. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Jun 4, 2026. The linked authority identifier is Q5472990. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1870.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
