About Pasjans (Łamaniec)
Pasjans (Polish for solitaire) is one of the daily games on Łamaniec, run by Ququplay alongside word puzzles such as Literada and Zlepka. It is the classic Klondike: seven tableau columns, four foundations to build up by suit from ace to king, and a stock you turn through.
The site describes it as a new, always solvable deal every day, with hints, undo and a ranking, free and without logging in. A move counter and the number of cards left in the stock (Talia) sit at the top, with Reset, Podpowiedź (hint) and Cofnij (undo) buttons. Earlier deals are kept in a dated archive, and you can change the table background.
It suits solitaire regulars who like knowing that every day's deal can be won, and anyone who wants to compare a result with other players on the same cards.

Tips
- Uncover face-down cards in the longest columns first.
- Only move a king into an empty column when you have one ready to follow.
