Shuffle 2 decks of playing cards together. Start by removing the jokers from two decks of cards and shuffling them all together.

Deal out 10 piles of cards in a horizontal line. Place ten face-down cards next to each other in a horizontal line. Deal ten more face-down cards on the original ones, and then repeat until all the piles have 4 cards. Add one more face-down card on the four left-most piles, then, deal another card face-up on each pile. From left to right you will have 4 piles of 6 cards, then 6 piles of 5 cards. Leave extra space on the table below the piles for the runs you'll be making—they'll be 13 cards long.
