Solitaire Classic - a highly addictive Klondike card game for everyone! Solitaire Classic is the perfect card game for every fan of the retro computer game classic and one of the best known and most fun single-player card games of all times. Solitaire is as simple as it is addicting. The goal is simple: you have to move all existing cards onto the four foundation piles. Achieving that is not that simple, however. You have to attach all cards to the piles on the bottom, in a descending order and with alternating colors. Uncover cards from the pile on the upper right, if necessary. You can also adjust the difficulty by choosing to always uncover three cards at once instead of one. On the upper left you have to first place the Aces (which count as 1) of each color. These are the basis of the foundation piles. Here you have to pile up all cards starting with the Aces, but this time in ascending order and of the same color, Ace to King. If all four foundation piles are complete, you have beaten the game.
