Cards Game in Javascript



In the previous lesson of game development we made a multiplayer snake game in html5 and in this lesson we will make a cards game using javascript and html5 drag and drop functionality. Drag and drop a card with smaller number on the card with greater number and complete the cards pattern from 7 to 1 to make a king in the empty boxes below. Fill all the empty boxes with kings to win the game.
