At last check there were a couple of dozen solitaire game versions for Windows Phone 7.  Jake Poznanski's Solitaire is one such version for your Windows Phone. The game follows the traditional solitaire game with a straight forward layout where you move your cards by touch.

Solitaire is a free game over at the Marketplace and to see if it's worth a download, skip on past the break.

The main screen of Solitaire has buttons to start a new game, access gaming options, and to view game instructions. The Main Screen also displays your gaming statistics that includes games won, games played, high scores and winning percentages.

Game options are minimal to include your draw mode (one or three cards) and your scoring methods (standard, Vegas, or no scoring).

The game screen has your hand layed out nicely with the deck in the upper left corner. Moving down the left edge of the screen you have a button to access the Main Menu, your score/time display, and an undo button. Along the upper right corner you'll find your home cells or stacks.

Game play can be done one of two ways. You can double tap on a card and it will move automatically to the most convenient position (not necessarily the best) or you can tap/hold and drag the card into position.

Solitaire by Jake Poznanski is a free, ad driven game. A banner ad appearing at the bottom center of the screen. It's not in the way but I wouldn't mind seeing a $.99 version of this game without the banner and larger cards. The game ran smoothly with no bugs, glitches or crashes experienced.

It may not have many bells and whistles but if you're looking for a free solitaire game for your Windows Phone, Poznanski's version is worth checking out.

You can download your free copy of Solitaire here (opens Zune) at the Marketplace.
