iSolitaire is a native version of Klondike Solitaire (same as XP Solitaire game) for the iPhone.

It’s in its early stages but the current features are:
– plays Klondike version of Solitaire
– double tap table for options screen where you can deal new cards, change the draw number (1 or 3) or show time/score
– nice surprise once you win (hint: see iSnake or Bounce for an idea what might happen)
– theme support. Add your own theme and easily switch via options screen. Included are default and leopard (thanks to sunsurfin) themes. I’m also looking for a real cool theme that changes the cards as well to be included in the core package
