How fast are you at solitaire on steroids?!
Just tap or click the side of the screen where the next card is one higher, or one lower than the bottom card. So if the bottom card is a 3 of Clubs and there is a 2 of Diamonds on the left, you tap on the left. And that's it!
Sounds easy? Think again!
Because the cards are continuously dropping down the screen, so you need to be as fast as possible.
