Preparation: Before you start the trick place the four Kings on top of the deck.
Tell your spectator(s) that this is a special royal deck and the Kings run it all. Start by making four piles: take about one-fourth the deck from the bottom, and set it on the table. Take another quarter from the bottom, and set it to the right of those. The third quarter goes to the right of the two piles, and the fourth (the rest of the cards) goes to the far right.
From the pile at far LEFT, place the top three cards on the bottom of the pile, then deal one card to each of the other three piles. Repeat this with each pile, moving from left to right.
Ok, now you're all set. Point to each pile and say "King of the Hill." Turn each top card face up, to show that the Kings have magically come to the top.
