Hi! I know how to play...you need to clear the cards away one at a time by clicking on an 'open' card (more on this later) that is one higher or lower than the card showing on the discard pile at the bottom of the screen. For example if a Five is showing, you need a Four or a Six to continue. A Two or a King can go on top of an Ace. In order to click on a card, it has to be 'open'; that is, it can't have any cards on top of its corners. If you run out of time or moves, the game ends!
I like this game; not much KC, but it's very quick!
