The aim of Perseverance Solitaire is to build all four suits up from ace to king using a standard 52-card deck.
To start all four aces are taken out and placed on the foundations while the rest of the deck is shuffled and dealt into 12 piles, four cards in each pile.
On the tableau (piles), cards are played in descending order by suit.
An empty pile can never be filled with any card.
On the foundations, cards are build up by suit.
The top card of a pile or a sequence of cards of same suit can be played to a pile.
Only the top card of a pile can be played to a foundation.
When all possible moves are made, the piles are picked up in reverse order and redistributed (by clicking on "Redistribute Tableau Cards" button) to tableau in piles of four as the remaining cards allow.
This is done until the game is won or becomes blocked with no possible move.
The game is won when all cards end up in the foundations.
