Klondike Solitaire is a free card game app that is based on the most popular solo card game in the world. This version is so popular because it was released on the Windows 95 operating system under the name Solitaire, and even though the game is technically called Klondike, most people would instantly associate Klondike with generic solitaire. Just like in the older Windows version, the object of the game is to sort the deck of shuffled playing cards through the game board so they eventually create four suited stacks.

The graphics for this version of the game are exceptionally beautiful, and the level of detail in the backgrounds and cards themselves is quite impressive. In the settings menu, you can select the attrition option to give the impression that you're playing the game during a mild summer evening.

There are other customizations you can make through the settings menu. The score calculation method can be changed at any time, and you can turn the sound effects on and off. You can even set the game to operate for left-handed people. The settings also allow you to control what sort of undo option you'll be able to use in the game.
