Both Singleplayer and Multiplayer are supported.
Select cards on the bottom by tapping them which sum is equal to the card in your hand and then take them.
If you don't know how to play just tap on the Magic Wand on the right. The computer will perform the Magic Move for you and you'll get very soon the idea how to play.
The game is fully 3D but it is very easy to control the cards. Cards on the bottom and in the hand can be drag and drop in order to reorder them.
