I'm in the UK. My sister taught me this as "American Patience" in the 1960's (it is not a straight Solitaire).
Object: To clear the tableaux and move all the cards to the 4 foundation piles, Ace through King, as normal. 1 deck (no jokers), all laid out to tableau face up, in piles of 3, each fanned to show underlying cards.
Initial layout: 16 piles of 3, with last four laid as 2 piles of two.
Only top card of each pile is movable to other piles with two or one in pile. Once the last card in a pile is moved to the foundation, the pile position is lost for further use.
Key rule: Top cards are moved to other piles that match the same value (3 on 3, J on J etc, suit/colour irrelevant). Aces on top of any pile can move to foundation as normal, enabling standard moves to Foundation thereafter. During play, groups of three of same value in a pile tend to build up, stopping the fourth of that value from moving until the foundation builds to that value. Common strategy is to aim for two piles with two of same value to prevent this.
Very rarely get through to foundation completion first go, so get a total of three "tries" - ie when no moves left, the foundation stays, remaining tableau gathered and reshuffled, and laid out again in threes as before, until only 4,5 or 6 cards remain to set into tableau;
- 6 remaining=> 3 piles of two
- 5 remaining=> 2 piles of two, 1 of one
- 4 remaining=> 2 piles of two
Love to know the most common name and get an electronic version on my android tablet.
