Classic Solitaire Pro is a timeless card game available on the iPhone platform. The game's objective is to build four stacks of cards, one for each suit, in ascending order from ace to king. Played with a single deck of 52 cards, the game presents 28 cards initially arranged into seven columns. Players aim to strategically move cards between columns and the four Home stacks to win.

Players must strategically start each Home stack with an ace and follow the rule of building columns in descending order from king to ace. Additionally, cards in columns must alternate between red and black, adding an extra layer of challenge. Classic Solitaire Pro also offers scoring based on moves made and time taken, with bonus points awarded for finishing in under 30 seconds.
