Solitaire! is a completely free version of the very popular Klondike game, which most people just call "solitaire". The game includes options for one- or three-card draws from the stock. The recycle of the stock is unlimited for both.
Klondike provides convenient features such as smart-dragging, one-click moves, and autoplay that combine to reduce the amount of tedious movement during the play. Other features include the ability to use any image on your Mac as a card back or game background, unlimited undo/redo of moves, statistics, automatic game save/restore, and user-adjustable card spacing in the tableau.
