250 Solitaire Collection is a set of more than 250 different types of Solitaire games. You may not have known there were so many variations of this game, but apparently there are.
You can read the rules and also watch a demo of each Solitaire game available. Once you start playing, the controls are really intuitive. Usually, you just need to slide your fingertip on the screen to move the cards around.
250 Solitaire Collection is an amazing free card game collection. Plus, the app also features some pretty good graphics; at least as good as you can expect from a Solitaire game.
