Solitaire 1826 Turkish shawl

In the collection of card games of 1826, a description of solitaire The Turkish shawl begins like this:
"Among the very few layouts in one deck, this occupies not the last place with its entertainment, giving the case to the decomposer to use some attention to unraveling the predicament of the cards, and to get out of it through special foresight".
Contemporaries of the poet A. S. Pushkin and Emperor Nicholas the First, and maybe they themselves, were puzzling over this solitaire.

The playing cards are the lower closing cards of the columns, you can shoot pairs of cards of the same value (two queens, two threes). Solitaire has converged if all cards are removed from all rows in pairs.

Depending on the sequence of moves, you can create a situation that there are no more available pairs. It is necessary to calculate possible combinations for several moves ahead.

Management: clicking on the bottom card in the column will show options for pairs to it, clicking on the second card will remove this pair.
You can zoom in and move the camera with a wheel and hold the mouse or pinch and swipe on the phone screen.

The more difficult the level and the more successful the analysis of solitaire, the more coins you can get for the game. Coins can be spent on abilities that facilitate the analysis of complex layouts:
* Cancel turn - will roll back a turn;
* Swap - change the order of two vertically adjacent cards in a column.
