Solitaire

Solitaire is the card game that needs no opponent. You against a shuffled deck, a bit of luck and a lot of planning. The goal is simple yet sneaky: all 52 cards end up in four foundation piles, one per suit, ascending from ace to king. The road there runs through seven tableau columns where you build order descending and in alternating colours.

The rules stick after two rounds. In the tableau you stack cards descending and in alternating colour - a red seven goes on a black eight, a black six on a red seven. Whole sequences can be moved at once. Only a king may go on an empty column. On the foundations it works the other way: same suit, ascending from the ace.

You draw new cards from the stock when nothing moves in the tableau. When a card lands face-up in the waste, you can bring it into play or straight onto a foundation. When the stock is empty you flip it over and start again - so there is always another chance to reach the one card you need right now.

Moves are comfortable drag-and-drop. You grab a card or a whole run, drag it to the target and let go. If the move does not fit, the card springs back with nothing broken. A score and a move counter run along so you can compare rounds and keep an eye on your efficiency.

Solitaire is the ideal pastime for a break: short enough for five minutes, deep enough to lose yourself in. Some deals are solvable, some are not - and that is exactly the appeal. One click reshuffles and the next round waits.
