Косынка Судоку

Klondike Solitaire is a mix of solitaire and Sudoku. The player opens the cards from the deck and puts them on the 9x9 field. Each card contains a number that must be placed according to the rules of Sudoku: without repetition in a row, column and 3×3 square. The main difficulty is that the player does not choose the number himself. You need to use the card that opened from the deck. This makes every move important and adds a solitaire mechanic: you can flip through the cards, flip the discard, and look for the best course of action. The game has several difficulty levels, highlighting possible moves, canceling an action, and checking the field. The controls are simple: you can drag a card onto the field or select a card and a cell by tapping.
