Solitaire Pro is a digital version of the classic card game, also known as Klondike. The object of the game is to build four stacks of cards, one for each suit, in ascending order, from ace to king. The game is played with a single deck of 52 cards, and the player starts with 28 cards arranged into seven columns, with the top card in each column face up and the rest face down.

To win, each Home stack must start with an ace, and the player can move cards between columns to uncover them. However, columns must be built in descending order, from king to ace, and cards in columns must also alternate red and black. The player can move single cards or sequentially organized runs of cards between columns. If the player runs out of moves, they can draw more cards from the deck.

Solitaire Pro offers a modern twist to the classic game with its user-friendly interface and customizable settings. It is available for free on Android 9.0 and provides a fun and challenging experience for players of all ages.
