Example:
In the above example you will see that there is a space behind the Five of Hearts, only the Six of Hearts can go into this space. Likewise only the King of Hearts can go into the space after the Queen of Hearts. Any Two can go into the open slot at the beginning of the second row. No cards can go after the Kings as they are the end of the line so to speak.
Once all your spaces are after kings, you must redeal. Below you will see that all spaces are behind Kings making further plays impossible.
At this point you must redeal, but you get to keep anything you have in place, in sequence from the beginning. The following shows a sample second deal. Notice the Two's remained, if they had been followed by other cards, all cards in sequence and suit would have remained.
That pretty much covers the gameplay. The rules are simple, but the game is hard.
